One of the stars of the fall garden at JLBG is the little-known Peshman’s Snowdrop, Galanthus peshmanii. This amazing Greek and Turkish species, named after the late Turkish botanist, Hasan Peşmen (1939-1980), was only officially recognized in 1994. It’s closely related to the better-known Galanthus reginae-olgae. Our nine year-old clump has been an absolutely wonderful performer.
We’ve been growing the fall-flowering Farfugium japonicum for nearly 40 years, and despite growing numerous cultivars as well as seedlings, had seen no difference in the standard yellow flower color, until a 2008 visit to the Georgia garden of plantsman Ozzie Johnson. There, I first met the cultivar, ‘Beni’, which in Japanese, means red flowers.
Plantsmen in search of red flower plants all share the same frustration when they find that ‘Beni’ almost always turns out to be orange, to those without horticulture color blindness. Nonetheless, I was thrilled to know that there was a mustard orange flowered selection. Thanks to Ozzie’s generosity, a division returned with us for JLBG.
After growing it for 15 years, we still don’t have enough to share, but have recently divided our original clump, and spread it around the garden to build up stock faster. The photo is it in the garden this week (mid-November). We’re hoping it won’t be too much longer before we can share this amazing selection. Hardiness Zone 6a-9b.
One of the frustrating things about growing and propagating plants is when you find an incredible plant, offer it for sale, and virtually no one buys it. Such is the case with the Texas native, Ageratina havanensis, aka: Havana Mistflower, Eupatorium havanense. This fascinating woody perennial, formerly classified as a eupatorium, forms a 3′ tall x 7′ wide mound of foliage, that’s smothered starting in late October with a dense blanket of white flowers. I can think of little else that gives you this much flower power in the fall sun garden. An array of butterflies and moths are regular visitors. The photo below is from mid-November this year. Located with enough space, there is never any required maintenance. Any idea why we never could get folks to purchase these when they were offered through PDN?
Putting on a show this week in the garden are the Living Stones. No, not Mick, Keith, and Ronnie, but the horticultural Living Stones, Lithops aucampiae. Our oldest patch starts flowering in early to mid November each year, growing beautifully under an overhanging rock.
For all the articles about how difficult they are to grow, and how they won’t take any frost, we’ve found it all to be completely fake gardening news. These were started from seed in 2018, and have now survived 11F in the ground with no ill effects. We have them planted in a soil mix of 50% Permatill gravel, 25% native sandy loam, and 25% compost, with an open exposure to the south.
We added two more species (L. hookeri and L. lesleii) to the garden almost two years ago and they have thrived equally as well. Sounds like the myth about Lithops being difficult to grow and not winter hardy is completely busted.
Another of our favorite fall alliums is the lovely Allium kiiense, which hails from the Honshu Japan penisula by the same name. Last year, we had so many plants that went unpurchased, we planted a mass instead of throwing them out. Below is that mass in full flower this week. Hardiness Zone 5a-9b.
Looking great in the garden in November are our collection of x Amarines. These are a fascinating man-made group of hybrids between two South African genera of bulbs, Amaryllis belladonna and Nerine, first described in 1961. These grow their foliage in winter, which is a problem in climates as cold as ours. If the foliage gets damaged in winter, they rarely have enough energy to flower the next year. We actually weren’t expecting any flowers this fall, since we experienced 11F last winter, so this is a lovely surprise. We find these grow best in open shade to part day sun, as long as the drainage is good.
Below are several selections from our collection of Hemskerk hybrids, introduced in 2012. The top is xAmarine ‘Anastasia’, followed by xAmarine ‘Elvi’, ending with xAmarine ‘Emanuelle’.
Flowering in the crevice garden in early November is the little-known South African bulb, Strumaria discifera ssp. bulbifera. These hail from the winter wet/dry summer region of the Western Cape, and have been right at home in the ground here since 2018. Okay, so it’s not as flashy as a tulip of daffodil, but to quote Abraham Lincoln, “for people who like that kind of thing, I think that is just about the kind of thing they’d like.”
Looking great in our trials in early November is Symphotrichium dumosum ‘HillandSchmidtii’. Also, known as Aster dumosus before its name change, this fascinating 2018 Zac Hill/Jeremy Schmidt collection from Wilkes County, Georgia has proven to be quite a winner, so it will certainly be slated for a future Plant Delights catalog. We initially though this was the plant formerly known as Aster pilosa, before Patrick straightened us out. Evidently, virtually everything in the trade as Aster dumosus is incorrectly named.
In full flower now is Patrick’s selection of the native Helianthus angustifolius from Berkeley County, SC. This widespread wetland, often shaded species can be found from New Jersey to Texas. As is the case for most species, each population varies in one or more traits. Most Helianthus angustifolius usually reaches 5′ in height, but this amazing compact selection matures at only 3′ tall x 7′ wide. Here, we have in growing in slight moist, but un-irrigated sandy loam ammended with compost, in full sun. I have a feeling this one is heading for the propagation shed next year.
We have a number of favorite legumes in the garden, but most flower in the spring or early summer. The star of the fall garden is undoubtedly Dalea bicolor var. argyaea, which starts flowering in mid-October. All summer, we get to enjoy the silver foliage, which thrives in our summers, only to be further rewarded in fall with the floral show. This amazing North American native hails from Texas and New Mexico, where it can be found in alkaline sandy uplands.
Flowering now in the garden is Dan Hinkley’s Mahonia eurybracteata ‘Indianola Silver’. This incredible plant is one of Dan’s collection with pewter foliage, that just glows in the fall garden. Mature size is 4′ tall. I picked this up on a 2006 visit to Heronswood, just before the nursery was shuttered by George Ball. Because this never made the catalog, it’s virtually unknown in most plant circles. Hardiness Zone 7b-9.
Colchicum autumnale ‘The Giant’ is in full flower in our alpine rock garden this week. This widespread Central European species bursts out of the ground for us in mid-late October with a stunning show. The cultivar, ‘The Giant’ has abnormally Y-U-G-E flowers. Hardiness Zone 5a-8b.
Flowering this week is the lovely fall-flowering Allium thunbergii. This specimen is a 1993 Dan Hinkley collection from the Heuksan Islands, well off the coast of South Korea. Many of the plants on the Heuksan Islands have been isolated so long, that they have speciated (evolved into a new species). In this case, this plant sort of keys out to Allium thunbergii, but not exactly. We find this to be a superb, fall-flowering rock garden specimen, and one we hope to get propagated in the future. The first bulbs will go back to Dan for his home garden. Hardiness Zone 6-8.
The beautiful Gaillardia aestivalis var. winkleri ‘Grape Sensation’ is still in full flower as we approach the end of October. This amazing, but quite rare blanket flower is only found in a small area of the East Texas pineywoods region. Although it’s currently listed as a variety of Gaillardia aestivalis, we feel it deserves to be elevated to species status, and am shocked that no taxonomist have tackled this yet. Good drainage and plenty of sun are keys to success. Hardiness Zone 7a-9b.
Gaillardia aestivalis var. winkleri ‘Grape Sensation’
Solidago mexicana ‘Endless Stares’, in flower at JLBG, is a wild, but almost unknown Southeast US native, which ranges in coastal settings from Maryland south into Mexico. This goldenrod is Patrick’s SC native selection, with stunning purple red stems all summer. We love the large size, but this probably freaks out most gardeners.
Through the years, we’ve killed far more than our share of Zauschnerias, California fuchsia, but a combination of building a crevice garden and planting the superb clone, Zauschneria canum var. arizonica ‘Sky Island Orange’, we have a winner. Our clump, which is in full flower in October, has been growing here since 2018. To say that perfect drainage is essential is a grand understatement.
Zauschneria canum var. arizonica ‘Sky Island Orange’
One of the top pollinator plants in the garden this month is this clump of adult ivy. All ivies clump, instead of run, once they gone through horticultural puberty, which usually happens around age 15. English ivy, Hedera helix makes a similar, but larger shrub, that flowers in July. The clump below is our selection of Hedera rhombea, which is a much smaller plant that flowers two months later.
Our selection, Hedera rhombea ‘Cheju’ is an adult selection that I found hiking through the woods on Cheju Island, Korea in 1997. Two cuttings we sent back rooted, and 26 years later has made an incredible, unpruned garden specimen. Pollinators include honeybees, native bumblebees, and an array of wasps and yellow jackets. Our native Carolina anoles perch atop the flower stalks, just waiting for lunch to arrive. The pollinators are so numerous, the plants give off a discernable buzz. As we try to constantly educate people, the insects don’t care where the plant originated.
In 2012, plantsman Hans Hansen and I were botanizing in the Balkans, when we drove up on a patch of flowering Aconitum superbum in a field at 4,200′ elevation, near the town of Kupres, Bosnia. Hans collected seed, since monkshoods fare far better in Michigan than they do in the heat and humidity of Raleigh, NC.
Years later, I was admiring a patch of monkshoods at Walters Gardens in Michigan, when I discovered that these were seed grown from the plants we found in Bosnia. Since they had thrived in Michigan, I returned home with seedlings to try in Raleigh.
Surprisingly, as you can see from the patch below, they have thrived in Raleigh, in both light shade as well as full baking sun, topping out between 4′ and 6′ in height. Interestingly, it doesn’t appear that Aconitum superbum is in cultivation, which is quite surprising. We’ll make sure these are fast-tracked into production now that we know how well they tolerate our summers. Hardiness is Zone 5a-8a, at least.
I can honestly say that no plant perfumes the garden better than the amazing Osmanthus fragrans ‘Conger Yellow’. We currently grow nine cultivars of tea olive, but none can hold a candle to the fragrance of this yellow-flowered clone. Anyone visiting the garden in September/October is dazzled by the fragrance from up to 200′ away…a feat that no other plant can match. Our 20 year old specimen is truly a sight and fragrance to behold.
Hemiboea subacaulis var. jiangxiensis ‘Jiangxi Bells’ is looking great in the garden over the last month. This gem is an amazing new, hardy gesneriad from a joint collection by Scott McMahon (Atlanta Botanic Garden), and Mark Weathington (JCRA). Discovered in Jinggangshan, China, this seems to be a new species to cultivation. The 1′ wide, fuzzy-leaf rosettes, spread via stolons to form a lovely deciduous groundcover. Starting for us in mid-September, the rosettes are each topped with a cluster of tubular pink flowers. Light shade, and slightly moist soil make the best show. Fingers crossed, this should show up in the next Plant Delights catalog. Hardiness is Zone 7b-10.
Hemiboea subacaulis var. jiangxiensis ‘Jiangxi Bells’Hemiboea subacaulis var. jiangxiensis ‘Jiangxi Bells’
Looking lovely this week in the garden is Crinum politifolium, which hails from Tanzania. Not many people think of East Africa as a source of Zone 7b hardy plants, but areas such as the Southern Highland hold a wealth of horticultural potential, especially for geophytes, that hasn’t been well explored.
We just love this surprisingly winter hardy cuphea (cigar plant). Cuphea cyanea, a North American native, looks so delicate, but it’s rock hardy here in Zone 7b. Our original plant came from Asheville gardeners, Peter and Jasmine Gentling, where it survived fine in Zone 6b/7a. Our plant continues to be in full flower in mid-October. As you can see, the native bumblebees are thrilled to have it around.
I posted photos earlier from our lycoris selection back in August, but the season extends through September and into October. Below are some of the later flowering varieties. With a selection of cultivars, you can easily have a lycoris in flower from early July until mid October.
Lycoris ‘Tipping Point’ looks like the common Lycoris radiata, but instead of yellow pollen, it has white, creating interesting anther tips.
Lycoris radiata ‘Tipping Point’
Lycoris x caldwellii ‘Eye Scream’ is a hybrid between two spring-leaf species, Lycoris longituba and Lycoris chinensis.
Our plants of Eysenhardtia texana ‘Uvalde’ are perfuming the air with their sweet fragrance in October. As you can imagine, it’s abuzz with pollinators. This Texas/Mexico native, known as Texas kidneywood, makes a 10′ tall shrub that’s quite heat and drought tolerant. The common name comes from the fact that the genus Eysenhardtia has been used for centuries by the indigenous peoples of Mexico and parts of Central America to treat urinary ailments. We’d killed this species once before due to our cold temperatures, but Patrick’s collection from Uvalde, Texas has proven to be rock hardy for us.
The shaggy blazing star, Liatris pilosa has put on quite a show over the last few weeks. Looking quite different in the garden than it did in the wild, this native from Delaware south to Florida enjoys bright sun and well-drained soils. Our plant is growing in one of our Permatill amended rock gardens. Hardiness is Zone 6-9.
The star of the fall garden this year has been Colchicum tenorii (recently corrected to Colchicum cilicicum), which has been flowering for weeks. Our clump of this Italian native bulb, began as a single bulb in 2000. Once the flowers finish next week, the large, green leaves will emerge and continue to grow through the winter, before finally going dormant in mid spring. This is growing in our full sun rock garden in a soil mix amended with Permatill. (Hardiness is Zone 4-8).
In full flower now at JLBG is the longspike tridens, aka: Tridens stricta ‘Buffalo Feathers’. Athough native from NC west to Texas, the genetics of our clump hails from a Wade Roitsch (Yucca Do) collection in Lee County, Texas, and is superior ornamentally in both form and longevity.
We have found this little-known ornamental grass to be an excellent garden addition, giving a Calamagrostis acutiflora-like presence in hot, humid summer climates where that popular grass fears to tread. Our plants have been in the ground for over three years, and we continue to be impressed.
We have been admiring the amazing Nerine angustifolias in our dryland parking lot berms over the last few weeks, and they are almost at peak bloom. These South African (Mpumalanga province) amaryllids are distant allies to the Southeast Asian genus Lycoris, although they keep their foliage, unlike lycoris.
Typically nerines don’t offer much winter hardiness here in Zone 7b, but this species has thrived in our trials since 2019. It’s our hope to finally have enough to share through Plants Delights in spring.
Here’s a new banana to add to the list of hardy species, Musa haekkinenii. This very new, compact-growing, species was first published in 2013, and named after Finnish Musa expert, Markku Häkkinen. Genetically, it’s a relative of Musa coccinea & Musa exotica, that hails from Phú Thọ Province of Northern Vietnam, where it was discovered in garden cultivation. Although it is reportedly wild further north in Vietnam, it has yet to be re-discovered in situ.
In the garden, it forms a dwarf 7′ tall x 10′ wide, freely offsetting specimen. For us the upright stalks of stunning scarlet red flowers begin in mid-September. So far, it has survived 11 degree F in ground with no protection. In Vietnam, it is referred to as Chuoi rung hoa do, which translates to wild red banana. We’ll do our best to make this available as soon as possible.
Looking lovely in the early fall garden are the xAmarcrinum. These are man-made hybrids between Crinum lilies and the South African Amaryllis belladonna. Despite the later not growing well here, the hybrids are quite amazing with their sweetly-fragranced flowers. All xAmarcrinum are somewhat similar in growth, with greatly reduced foliage from most crinum parents. The cultivar below is xAmarcrinum ‘Summer Maid’. Hardiness is Zone 7b-10.
With September temperatures reaching 100 degrees F in Raleigh, is it any wonder we’re thinking about snow? Looking lovely after a recent rain is the rain lily, Zephyranthes ‘Summer Snow’. We grow a huge number of rain lilies, but none out flower our 2014 introduction of a hybrid between Zephyranthes candida and Zephyranthes citrina. This started its life as 5 original bulbs.
More lycoris continue to open every day. Their flowering season coincides quite close with the hurricane season. These amazing amaryllids pop up almost overnight, sans foliage. If you’re curious to take a deep dive into the genus, check out our lycoris study gallery
Lycoris chinensis is a spring-leaf species from China.
Lycoris chinensis ‘Piedmont Gold’
Lycoris longituba is the tallest species with the largest flower. It is typically white, but can come in yellow and pink. Anything other than white is quite rare.
Lycoris longituba ‘Butterfingers’
Lycoris x incarnata ‘Peppermint’ is a hybrid of Lycoris longituba x Lycoris sprengeri. This is an exceptional plant as you can see below.
Lycoris x incarnata ‘Peppermint’
Lycoris x longitosea is a hybrid of Lycoris x incarnata and Lycoris radiata. This is an extraordinarily rare hybrid.
Lycoris x longitosea ‘Super Streamers’
Lycoris x sprengensis is a group of hybrids between Lycoris sprengeri and Lycoris chinensis, both spring-leaf species. This is an old, but impossible to find hybrid from the late Sam Caldwell.
Lycoris x sprengensis ‘Haysper Gold’
Lycoris ‘Summer Moon’ is a yet to be introduced hybrid from lycoris breeder Phil Adams of the same cross above.
Lycoris x sprengensis ‘Summer Moon’
Lycoris ‘Matsuribune’ is a hybrid from the late Mr. Komoriya of Japan, who crossed Lycoris sanguinea and Lycoris sprengeri. We can’t really grow the orange flowered L. sanguinea due to our summer heat, but this hybrid excels.
Lycoris x sprenguinea ‘Matsuribune’
Lycoris ‘Yoimachi’ is another cross with the same parentage above, also from the late Mr. Komoriya.
Lycoris x sprenguinea ‘Yoimachi’
Lycoris ‘Gennen’ is an exceptional Komoriya hybrid, resulting from a cross of Lycoris radiata x Lycoris chinensis.
Alstroemeria ‘Summer Relieve’ has been a real star in our trials. This patch is now 3 years old, and consists of 9 original plants. Flowering typically starts for us in early May, slows during the worst heat of summer, and picks up again as temperatures cool. Hardiness Zone 5b-8b.
Looking quite lovely atop our crevice garden is Osmanthus heterophyllus ‘Hariyama’. This incredibly heavily-spined seedling of Osmanthus ‘Sasaba’ was brought to the US by plantsman Ted Stephens, who acquired it from Ishiguro Nursery in Japan. Our 15 year old plant has topped 10′ in height. Earlier in the fall, it was adorned with small, fragrant white flowers. Despite the small congested foliage, this is not a small plant, but where an oriental specimen plant is needed, this is very special.
I’ve posted about daphnes a couple of times this year, but can’t help post again now that we’re in December and still have two daphnes in full flower, despite two nights at 25 degrees F.
The top is Daphne collina from Southern Italy, and the bottom is Daphne x napolitana ‘Bramdream’…a hybrid of Daphne collina x Daphne cneorum var. pygmaea. These are growing in our dry crevice garden in a soil mix of 50% Permatill gravel. It seems obvious that the Daphne collina is the source of the continuous bloom. Winter hardiness is Zone 6a-8b (top), and Zone 5-8b (bottom).
Those old enough to remember the incessant Volkswagen commercials of the 1990s probably still can’t get the word Fahrvergnügen out of their brain. We’ve commandeered the term, which means “The Joy of Driving” to Farfugnügen…the joy of growing Farfugium.
We think more people should be growing this amazing genus of plants in the aster family. While most named selection are made for foliage only, with a less than stunning floral show, here is one of our favorite flowering selections, Farfugium ‘Jagged Edge’, that we’ll make available for the first time next year through Plant Delights. These fall-bloomers put on quite a show, which in most climates, ends with the first hard freeze. Hardiness zone 7b to 10b.
We love the fall-flowering show of Camellia sasanqua, that’s underway now at JLBG. Here are a few of our favorites, starting with the amazing Camellia sasanqua ‘Fall Fantasy’. This hybrid from the late Chapel Hill camellia guru, Cliff Parks is unlike anything we’ve seen both in number of flowers as well as the incredible double pink form.
Camellia sasanqua ‘Fall Fantasy’
Camellia sasanqua ‘Ginba’ is Japanese introduction with lovely frosted-tipped leaves. This is also a slower growing selection.
Camellia sasanqua ‘Leslie Ann’ is truly breathtaking. With a much more open habit, this cultivar is truly elegant. In form, it resembles a flowering cherry, far more than a camellia. This is an introduction from Alabama’s Ray Davis in 1960.
I’ll end up with another truly unique selection, also from the late Cliff Parks. Camellia sasanqua ‘William Lanier Hunt’ is the closest to blue flowers we’ve seen. Each pink flower has a blue cast that increases as the flowers age. This selection is named after the late NC plantsman of the same name.
For several years, we’ve been fascinated with the genus, Hemiboea, a collection of 23 species of African Violet relatives, all native to China. We currently grow five of those, and two others that are still to be identified. On a 2020 trip to England, we picked up Hemiboea strigosa, which has been flowering beautifully here at JLBG, starting in early fall. The Latin word “strigosa” means stringy, which certainly describe the mat of stolons which lie right at the soil surface. So far, our plants have been through two winters, where they fared very well. If the good performance continues, we will start propagation soon.
Begonia U-521 is a species we got from a customer in Alabama, which has sailed through our winters at JLBG since 2017. Flowering begins for us in early fall, with clusters of large pure white flowers, which hide just below the leaves. For those unfamiliar with Begonia U-numbers, these are assigned by he American Begonia Society for plants new to cultivation that represent potential new species.
This amazing begonia was purchased by begoniaphiles Charles Jaros and Maxine Zinman from the Bangkok Market in Thailand. For those who haven’t visited this amazing marketplace, it’s a massive venue where local vendors (nurserymen and collectors) sell their wares.
It turns out that this species came from the wild via a collector who lives on the border of Thailand and Cambodia, where no plants should be winter hardy here in Zone 7b. We’re not aware of anyone currently working on naming new begonias from that region, so to offer it, we’ll need to assign a cultivar name, which will remain connected to the plant, once it becomes a published species.
Have you ever been seated by someone who exercised no self control when it came to their application of perfume to the point that they left you gasping for fresh air? Well, there’s a shrub with the same degree of insanely sweet scented flowers, Osmanthus heterophyllus ‘Kaori Hime’.
This fascinating Japanese selection of the Japanese/Korean/Taiwanese native shrub is renown for its tiny foliage as well as the multitude of tiny white flowers with an over-the-top perfume sweet fragrance. Our plant has been flowering for nearly a month…an incredible treat for the fall garden. Our 10 year-old specimens measure 7′ tall x 12′ wide…much larger than most on-line vendors indicate.
Most folks have grown butterfly bushes in the genus buddleia, yet few garden visitors recognize this fascinating species from our 1994 botanizing trip to Northern Mexico. I should add that most buddleias on the market are developed from the Asian species, and virtually none from the less colorful North American species.
Buddleia cordata ssp. tomentella grows in rocky, bone-dry hillsides in the mountains of Northern Mexico near the town of Los Lirios at 7,000′ elevation. I was only able to find a single seed, but fortunately, it sprouted, and 28 years later, this amazing specimen is the result.
One of the cool things about Buddleia cordata ssp. tomentella is the insanely fragrant flowers, which start for us in early fall, and continue all winter…a trait you won’t find in any other temperate shrub of which we’re aware. As you can imagine, it is awash with an array of pollinator insects The flower color is a dusty white, so this will never be a plant that will make it to the shelves of your favorite box store. That said, it’s a plant we wouldn’t be without in our garden.
Flowering now in the garden is the fabulous Fatsia japonica ‘Ripple Effect’. Although this isn’t currently on the market, we’re working diligently on propagation. Thanks to the US National Arboretum for sharing this amazing selection, which we hope to introduce in the next couple of years.
Here’s a garden shot just prior to our expected first freeze of the year. Foreground to back: Muhlenbergia lindheimeri, Salvia darcyi, Juniperus conferta ‘All Gold’, Cuphea micropetala, Salvia ‘Phyllis Fancy’.
Garden just before the first freeze – Foreground to back: Muhlenbergia lindheimeri, Salvia darcyi, Juniperus conferta ‘All Gold’, Cuphea micropetala, Salvia ‘Phyllis Fancy’.
Elliott’s aster (Symphyotrichum elliottii) is the absolute last of our asters to flower at JLBG. It doesn’t begin to flower until the first of November and withstands the mild frosts of October like they didn’t even happen. It is naturally found in tidal freshwater marshes and other moist open sites from the Virginia and Carolina coastal plain south to Florida and west to Louisiana. Though it hails from moist environments it thrives under general garden conditions if the soil isn’t allowed to become too droughty.
Symphyotrichum elliottii
The plant has a lot to recommend it besides the time of flower. It forms stiff stems rising 5-6’ tall crowned with a dense pyramidal arrangement of inflorescences of pale pink with a hint bluish-purple ray flowers and bright yellow disk flowers. The lack of lanky branches allows this tall aster to display its flowers without flopping all over the rest of your garden in the manner typical of asters. It spreads via rhizomes, so you need to be sure to give it space to roam a bit. It provides a dramatic impact when planted at the back of borders. Though it spreads, it doesn’t roam far from the parent plant and can be easily kept in place by yearly thinning of the outer edges of the clumps.
Symphyotrichum elliottii
The most outstanding feature of this beautiful aster to me is the number and diversity of pollinators it supports. I don’t think I’ve ever seen a plant that attracted more. In addition to swarms of honeybees, bumblebees, carpenter, and solitary bees the flowers draw in numerous pollinating flies, halictids, moths and skippers. I love plants that extend the color season and though we all think about early spring, we really should also plant to extend our love affair with color into the leafless season and Elliott’s aster does this is a big way.
Raise your hand if you grow the native October Flower? Polygonella polygama is a little-known, but absolutely amazing wildflower in the Buckwheat family, suited to well-drained, sunny gardens. Although completely non-descript through spring and summer, when people are buying plants, it bursts into flower in October, also when no one is buying plants. Below is our plant strutting it stuff in one of our full sun rock gardens in mid October. Polygonella polygama is native from Virginia southwest to Texas, along the coast. Winter hardiness should be at least Zone 7b and south.
With enough plant diversity, there are all kind of possibilities to target floral interest for certain seasons or even holidays. Since the Halloween season is just past, here are a couple of seasonal favorites.
If there’s ever been a plant designed for the Halloween holidays, Cuphea micropetala has to be near the top of the list. This amazing perennial hails from the subtropical regions of Central and Southwestern Mexico. Below is our plant on Halloween this year. Flowering for us typically starts in early October. Despite its warm origins, it’s a reliable perennial here in Zone 7b.
Cuphea micropetala
The other can’t miss seasonal favorite, is our 2005 introduction of Gladiolus ‘Halloweenie’. This crazy gladiolus from South Africa, skips the typical spring flowering season, and instead, starts flowering the week of Halloween.
Flowering today at JLBG is one of the tiniest of the geophyte aroids, Ambrosina bassii. This tiny gem, which matures at a whopping 1-2″ in height, is native to the Mediterranean region from Southern Italy to Northern Africa, where it grows on woodland slopes over alkaline rocks. There is only a single species in this little-known genus.
Mid-October is flowering time for the widespread (Canada south to Texas) native oblong aster, Aster oblongifolius (aka: Symphyotrichum oblongifolium). This amazing plant forms a large clump to 2′ tall x 8′ wide. This is the clone Aster ‘October Skies’, which is quite similar to the other widely grown clone, Aster ‘Fanny’. Average to dry soils in full sun is the key to success. Hardiness is Zone 4a-9b.
The shrubby North American native salvias including Salvia greggii and Salvia microphylla are spectacular plants in the fall garden. The same goes form the hybrids between the two species, known as Salvia x jamensis. Here is our clump of Salvia x jamensis ‘Blast’ looking absolutely stunning in late October. Flowering is heaviest in spring, slowing in summer, but again equaling it’s spring show in fall. Hardiness is Zone 7a-9b, and possibly a good bit colder.
You’re probably thinking that we’re referring to a branch of the military, but instead we’re writing about a plant by the same name. x Amarine is a man-made amaryllid hybrid, created from a bi-generic (think humans x gorillas) cross between Amaryllis belladonna and Nerine. As a rule, most Amaryllis belladonna are fairly ungrowable in the Southeast US, as are most nerines. In theory, the hybrids should be completely ungrowable, but fortunately, that isn’t the case.
Amaryllis belladona is difficult for us to flower because the foliage, which grows during the winter, gets blasted by cold weather, which in turn prevents it from sending energy to the bulb, resulting in a lack of flowers. The same holds true with the hybrid x amarine. It’s only after a mild winter or two that the bulbs have enough energy to produce flowers. Thank goodness, this is a great year for x amarines to flower. Below are one of our patches of x Amarine ‘Anastasia’, which has been flowering at JLBG for several weeks.
You go straight through to the round of botanical superstars if you recognize this little-known southeast native (SC to Florida), Piriqueta caroliniana. This Patrick McMillan collection from coastal SC has thrived all summer in our full sun rock garden, flowering constantly, with new flowers opening every other day. This oddity is a member of the Turneraceae family, which comprises nine other equally obscure genera. We’ve yet to determine if this will actually make a good garden plant, but evaluation continues. Hardiness north of Zone 8a is unknown.
One of the stars of our late summer/early fall garden has been our selection of Chrysopsis mariana ‘Little Miss Sunshine’. We made this roadside collection of this East Coast native in 2020 in neighboring Orange County, NC, unsure of what we had collected, but loving the purple stems of this clone. This planting in our rock garden has produced an amazing 18″ tall x 2′ wide specimen that glows for months. Dry soils and at least half day sun are the keys to success. We’ll start propagating this showy, clumping native perennial in spring. Winter hardiness is Zone 4-8.
If you think you know mahonias, then check out this little-known species, flowering now at JLBG. Mahonia nitens is endemic to Guizhou and Sichuan, China. This is a form selected by Japanese plant explorer, Mikinori Ogisu. For us, the plant matures our at 4′ tall x 5′ wide, with flowers that appear orange, due to the color of the flower buds. Hardiness is unknown north of Zone 7b.
Looking lovely in the garden today is the fall-flowering geophyte, Sternbergia sicula. This Mediterranean native is found in the wild growing on alkaline hilly sites. Some taxonomists list it as a subspecies of the more common Sternbergia lutea, but it seems consistently smaller. At JLBG, our plant thrives in the crevice garden. Hardiness is Zone 6a-8b.
Looking good in the garden now is Begonia taiwaniana ‘Alishan Angel’, which is our 2008 collection from 6,500′ elevation in Taiwan’s Yushan Province. This specimen has now been in the ground since 2010, and is thriving in a fairly dry woodland location. We introduced this selection in 2020 and will be offering it again in 2023. Hardiness is Zone 7b-9b at least.
Our 2008 introduction of a selection of our native Yucca x gloriosa ‘Lone Star’ has been absolutely splendid in the garden as the fall season begins. Yucca x gloriosa is a natural hybrid of Yucca aloifolia and Yucca filamentosa. We absolutely love that these flower spikes appear at a time when most other plants are past their seasonal prime. Winter hardiness is Zone 7a-9b.
Most folks are familiar with the mysterious Howard Hughes, but we have an equally mysterious “Howard” in horticulture. Flowering well now in the gardens at JLBG is the amazing xHowardara ‘Riley Kate’. This fascinating hybrid was created by Texas bulb guru, Dr. Dave Lehmiller, who crossed a Hippeastrum (amaryllis) and a Sprekelia (Aztec lily), and a Zephyranthes (rain lily). Lehmiller’s cross resulted in five different named cultivars and were subsequently named after the late Texas bulb guru, Dr. Thad Howard.
Creating a trigeneric hybrid is beyond rare, since it isn’t supposed to happen according to the rules of botany. Consequently, the introduction of the first clone sent taxonomists into a frenzy trying to publish new research to re-combine the genera involved into a single genus, so as not to have their rules violated. xHowardara’s occasionally flower for us in mid-summer, but peak flowering is always in September and October in our climate. Hardiness is Zone 7b – 9b, at least.
We’ve had Salvia ‘Rockin’ Deep Purple’ on trial since 2018, and it’s now headed for our January Plant Delights catalog. Although we love the Argentinian Salvia guaranitica, it spreads far too fast to be useful in many of our garden beds. We have been trialing a number of hybrids with Salvia guaranitica and an array of different clumping species to find one that has winter hardiness, but doesn’t take over the garden.
Salvia ‘Rockin’ Deep Purple’ from California’s Brent Barnes, has lived up to all of our expectations, as long as you have enough space. For us, a single clump measures 5′ tall x 10′ wide…a far cry from the 3.5′ tall x 2.5′ wide size that’s often marketed on-line. Below is an image of the flower power it’s still showing in early October. The bumblebees love it as much as we do.
Just like the rock group of the same name, these fascinating living stones also look quite old and wrinkled. The genus Lithops are tiny succulent plants native to the deserts of South Africa. Despite virtually all references on-line, they make great garden plants…as long as you have a crevice garden, and grow them when they will not receive any rain in the winter months. These are 4 1/2 years old from seed.
Our plants of Lithops aucampiae have just started their flowering season last week, having sailed through winter temperatures of 16 F last winter, and seemingly enjoyed our hot, humid summers. We’re hoping for single digits F this winter, so we can really put them to the hardiness test. In the meantime, we’ll enjoy the fall flowering season.
How many folks are growing Hypericum hypericoides (St. Andrew’s cross)? The name translates to hypericum that looks like a hypericum….duuuh. We love this native shrub which hails from New Jersey southwest to Texas. St. Andrew’s cross typically matures at 2.5′ tall x 5′ wide and adorned from May through September with small, light yellow flowers, which form an “x”, hence the common name.
In the wild, Hypericum hypericoides is usually found in slightly acidic to slightly alkaline sandy soils, often in pine savannas, but in cultivation, they seem quite adaptable to an array of garden conditions from sun to part sun. In form, it resembles a Helleri holly with yellow flowers. The photo below is a 2 1/2. year old plant at JLBG. Winter hardiness should be Zone 6a-8b at least.
We love the genus Hydrangea, but are really fascinated by those at the far end of the family tree. While most hydrangeas flower in late spring, we actually have a couple flowering now we’d like to share.
The first is Hydrangea involucrata, a native to both Japan and Taiwan. The word “involucrata” indicates it has some serious involucres (the bracts surrounding the inflorescence). The first image shows the plant in bud, the second in full flower, and the third image is after the flower color has faded. All three stages are on display at once in the garden this week. They typically reach 6′ in height and width. Winter hardiness is Zone 6a-8b.
Hydrangea involucrata in budHydrangea involucrataHydrangea involucrata
Hydrangea amamiohshimensis (below), from Japan’s southern Ryuku Islands, was once considered a hydrangea cousin, until a 23andMe test confirmed it was actually a true hydrangea. Prior to the test, it belonged to the genus Cardiandra, which was effectively a perennial hydrangea, dying back to the ground each fall like most perennials. It too is in full flower in the woodland garden this week. Perhaps now that it has a recognizable name, more folks will be willing to grow it. This is the only one of the four former cardiandra species that has survived in our climate.
Raise your hand if you grow the woodland perennial, Collinsonia? These mostly fall-flowering, clumping perennials in the mint family (Lamiaceae) are wonderful elements for the woodland garden at a time when little else is flowering. Named by Linnaeus to honor English botanist Peter Collinson (1694–1768), the genus Collinsonia contains 11 species of which 4 are native to North America. Five species are native to China, 1 to Taiwan, and 1 to Japan. Pictured below in flower this week is Collinsonia punctata, which hails from South Carolina west to Louisiana. Winter hardiness is unknown, but we guess Zone 7a-9b, at least.
Now that fall has arrived, we’re all enjoying peak plume season for many of our favorite ornamental grasses. Unfortunately, there are a few significant mix-ups in the trade. The top photo is our native Eragrostis spectabilis, known as purple love grass. I’ve long admired this beautiful, but short-lived native, but have declined to offer it because of its propensity to seed around much too vigorously in the garden. In prairie restorations or less-tended gardens, it can be a spectacular addition. Hardiness is Zone 5-9.
Eragrostis spectabilis
Because most nurserymen aren’t plant taxonomists, you can perform a Google images search and find several on-line vendors who pretend to offer Eragrostis spectabilis, but show photos of the grass below, known as Muhlenbergia capillaris. Who knows which of the two they are actually selling.
If that’s not confusing enough, the plant below is known in the trade as Muhlenbergia capillaris or Gulf Coast muhly grass/pink muhly grass. The only problem is that this is actually a different muhlenbergia species. All of us have taken this name for granted, but as our Director or Horticulture/Gardens, Patrick McMillan taught us, all commercial plants labeled as such are actually Muhlenbergia sericea. We are updating our records and this name change will be implemented in the near future.
The misidentification originated with a Florida taxonomist, who mistakenly lumped three muhlenbergias together…a problem that can occur when you only study dead/smashed plants in a plant herbarium. As it turns out, the two plants, Muhlenbergia capillaris and Muhlenbergia sericea (also formerly known as Muhlenbergia filipes) are nothing alike.
Muhlenbergia sericea (sold as M. capillaris)
The true Muhlenbergia capillaris is a rather homely plant that few folks would want in their garden. Muhlenbergia sericea, on the other hand, is a stunning ornamental plant, commonly known as sweet grass, and used for making those amazing hand-woven baskets that you find for sale in towns like Charleston, SC.
Such nomenclatural faux pas take decades, at least, for nurseries to get the names corrected since the public knows and purchases plants under the wrong name. This problem is far too common. The shrub, Ternstroemeria gymnanthera, was originally mistakenly identified as Cleyera japonica, and that mistake still persists over five decades later. Most gardeners despise name changes, often not realizing that many instances like these aren’t changes, but instead corrections of an earlier identification mistake.
You can learn more details about the mix up by reading Patrick’s article about pink muhly grass.
In our hot, humid climate, we really struggle with keeping most cultivars of Caryopteris x clandonensis alive for very long. A lovely exception in our trials has been Caryopteris ‘Gold Crest’, a recent introduction from the plant breeders at Ball Hort. Here is our three year old clump in the garden this week. The foliage is deliciously fragrant…more so than any other caryopteris we’ve ever grown, and the native bees find it incredibly attractive. We’ll be adding this to the new Plant Delights catalog in January. Winter hardiness is Zone 6a-9b.
I’d grown quite a few eryngiums…49 different ones, in fact, before Patrick shared Eryngium ravenelii with us in 2015. Who knew we were missing one of the best eryngiums in the entire genus! Today, Eryngium ravenelii holds several places of honor in our garden, where we can watch the myriad of pollinators who regularly stop by for a nectar snack during flowering season (mid-August to late September).
Eryngium ravenelii was named for American botanist, Henry William Ravenel (1814-1887). In the wild, Eryngium ravenelii grows in standing water in flooded ditches, alongside sarracenias (see bottom photo). We’ve now seen them in the wild in both North Florida and South Carolina, where they grow in calcareous-formed soils. In the garden, they thrive in an array of slightly acidic soils as long as the soil is reasonably moist.
We love fall not just because of the weather, the colorful foliage, the fall bloomers, but also for the fall fungus. It seems like some of the most incredible fungus of the year happens in fall. When we go outside to take plant photos, it’s hard to resist the amazing fungi as well. Like sand castles at the beach, fungi are quite ephemeral, so our only memories are through captured images. Here are few shots from the last week.
In flower this week is the amazing ginger lily, Hedychium ‘Flaming Torch’…our 1999 introduction, with its’ fragrant peachy flowers is still looking great! This is another of those plants that never sold particularly well, so we haven’t offered it since 2016. Winter hardiness is Zone 7b and warmer.
Flowering this week at JLBG is the amazing Miscanthus transmorrisonensis. Many gardeners, who blindly believe everything they read/hear think the genus miscanthus is the horticultural version of the devil itself. Like everything in life, it’s all about those pesky details, which so many people simply don’t want to be bothered with.
Most miscanthus in the horticultural trade are selections of the species Miscanthus sinensis. Some selections of that species reseed badly and should be avoided in gardens. Others are sterile or nearly so, and unquestionably still deserve a place in American landscapes.
If we make good/bad evaluations at the species level, what would happen if visitors to the earth had their first encounter with a Homo sapiens that was a less than ideal representative of the species at large. They could easily assume that the entire species was a problem and should be eliminated. It’s fascinating that such species based prejudices are acceptable with ornamental plants, but not with people.
Then there are species, which have proven themselves to be complete without seed in our climate, such as Miscanthus transmorrisonensis. All plants in cultivation all appear to be derived from a 1979 Ferris Miller (Chollipo Arboretum)/ Paul Meyer (Morris Arboretum) collection at 9,500′ elevation on Taiwan’s Mt. Daxue. We have grown this for 30 years in rather good conditions, and have yet to see a single seedling. The beauty of this species is that it flowers continuously from summer into fall. I guess it’s too much to ask for environmental fundamentalists to actually pay attention to facts.
Our 12 year-old stone oak, Lithocarpus glaber is looking fabulous this month, as it has come into full flower in early September. We love the stone oaks, which contrast to regular oaks in the genus, Quercus, by having upright insect-pollinated flowers, compared to wind-pollinated, drooping flowers in the genus Quercus, and by having exclusively evergreen foliage. Lithocarpus glaber is native to China, Japan, and Taiwan.
Flowering today at JLBG is Liriope gigantea ‘Lynn Lowrey’. This selection is named after the late Texas plantsman, and is the largest form of the largest species of monkey grass. This tight clump former can reach 3.5′ tall, when happy. The flowers don’t emerge until early September, making it one of the latest liriope species to flower. We offered this a couple of times, but so few people purchased it, we dumped out most of the crop and planted the rest around the garden. We think it’s pretty darn cool. Winter hardiness is at least Zone 7a-9b.
Just finished flowering in our crevice garden is the amazing member of the Amaryllis family, Acis ionicum. This little-known Albanian snowbell hails from small areas of Coastal Albania and Western Greece, as well as a few of the adjacent islands. The flowers of this species are quite huge, compared to the better known A. autumnalis. In the wild, Acis ionicum grows in rocky, calcareous hillsides, so it feels right at home in our recycled concrete crevice garden. Hardiness is probably Zone 7b and warmer…at least.

The amazing Hedychium deceptum from India, has recently burst into flower here at JLBG. This species is fairly new to commerce, but has proven to be an amazing, compact-growing specimen that thrives even in our full sun. The dark cinnamon calyces really make the scarlet flowers stand out. We rate this as hardy to Zone 8a, but that’s because we simply don’t have enough data yet, but we’ll be very surprised if it’s not fine in Zone 7b.

The genus rhodophiala is in a state of flux. Some taxonomists believe the genus actually doesn’t exist and should be merged with rain lilies, while others consider it a perfectly valid genus with 27 species. Oh, the joys of taxonomy. To most gardeners, the genus rhodophiala are simply dwarf hippeastrum (horticultural amaryllis), the most commonly grown of which is the South American Rhodophiala bifida, which ranges natively from Southern Brazil into adjacent Argentina.
Rhodophiala bifida starts flowering for us in mid-August, alongside the emerging foliage. Most Rhodophiala on the market are the clonal Rhodophiala bifida ‘Hill Country Red’, brought to the US by German born Texan botanist, Peter Henry Oberwetter circa 1890. This clone is virtually sterile when grown alone, but will produce viable seed when grown adjacent to another clone.
Below is the clone ‘Hill Country Red’, followed by some of our selected seedlings, all photographed here at JLBG over the last couple of weeks. The best conditions are full sun to light filtered shade, and average moisture to dry soil.
Rhodophiala bifida ‘Hill Country Red’
Rhodophiala bifida ‘Harry Hay’ seems to be the only named clonal selection grown in the UK. We imported this during our 2020 UK trip.
Below are two fascinating plants from our breeding. The first is a cross of Rhodophiala bifida x Lycoris longituba. In theory, this bi-generic cross shouldn’t work, but the flower arrangement sure resembles a lycoris more than a rhodophiala.
Rhodophiala bifida x Lycoris longituba
This cross is of Rhodophiala bifida x Sprekelia formosissima is another impossible bi-generic cross. Notice the three petals are one size, and the other three petals are larger. We’ve never heard of this happening in rhodophiala, so perhaps we’re on to something.
Rhodophiala bifida x Sprekelia formosissima
The only other Rhodophiala species, which we’ve had any luck with is the Chilean Rhodophiala chilense. Below are two forms, both of which flowered this spring.
We’ve just enjoyed peak surprise lily week at JLBG. The lycoris season starts for us in early July and continues into early October, but the last two weeks of August is peak bloom. Below are a few samples from the last few weeks.
The first two image are our field trials, where lycoris are studied, photographed, and evaluated for possible introduction.
Lycoris field trials @ JLBGLycoris field trials @ JLBG
There are only 6 lycoris species (despite what you read on-line). Four of these have foliage produced in spring, and two have foliage that emerges in fall.
Lycoris longituba is a spring-leafed species with flowers that range from white to pink, to yellow/orange.
Lycoris chinensis is a spring-leafed species with bright gold/orange-gold flowers. There is little variability in the color of this species.
Lycoris chinensis ‘Piedmont Gold’
Lycoris sprengeri, whose foliage emerges in spring, is the only pink flowered species, almost always with a blue petal tip.
Lycoris sprengeri ‘Soft Cloud’
Lycoris sanguinea is the fourth spring-leafed species, but one that performs quite poorly in our climate, and consequently rarely flowers for us.
Lycoris radiata is one of only two fall-leaved species. Lycoris radiata var. pumila is the fertile form, while Lycoriis radiata var. radiata is sterile and consequently never sets seed. There is little variability with regard to color, but there is great variability with regard to bloom time. Lycoris radiata is the earliest lycoris to flower in July and the last lycoris to flower in October.
Lycoris radiata ‘Fourth of July’Lycoris radiata with white pollen
Lycoris aurea is the only other fall-leaved species. In appearance, it is indistinguishable from the spring-leafed Lycoris chinensis, except that the foliage emerges six months earler.
Lycoris aurea ‘Landing Pad’
Lycoris traubii is a hotly debated plant in taxonomic circles. Occurring only in Taiwan, some taxonomists insist on it being its own species, while other simply find it a form of the mainland Chinese Lycoris aurea…similar to the debate about Taiwan’s political status. Until we see other evidence, we view it as a form of Lycoris aurea.
Lycoris aurea var. traubii
All other lycoris are hybrids. Sadly, botanists continue to name new lycoris species, but after having grown each, we have yet to find any that are anything more than a previously named naturally occurring hybrid. Below are a few of the validly named hybrids.
Lycoris x albiflora is a group of naturally occurring crosses between the two fall-leafed species, Lycoris aurea and Lycoris radiata. Most emerge yellow and age to pink-blushed. If these hybrids cross back to the Lycoris radiata parent, the hybrids take on lovely orange shades.
Lycoris x albiflora ‘Yellow Cream’
Lycoris x caldwellii, named after the late Lycoris breeder, Sam Caldwell, is a hybrid between the spring-leafed species, Lycoris longituba and Lycoris chinensis.
Lycoris x caldwellii ‘Gold Crown’
Crosses between the fall-foliaged Lycoris radiata and the spring-leafed Lycoris sprengeri have been made more than any other interspecific lycoris cross. We currently grow over 200 clones of this hybrid, with flower colors that range from solid pink to bright red, and everything in between. Backcrosses onto one parent or the other influence the flower color expression.
Lycoris x rosea ‘August Red’Lycoris x rosea ‘August Rose’Lycoris x rosea ‘Berry Awesome’Lycoris x rosea ‘Cherry Crush’Lycoris x rosea ‘Cotton Candy’Lycoris x rosea ‘Magenta Magic’Lycoris x rosea ‘Mini Me’Lycoris x rosea ‘Natsu no Odoriko’
Lycoris x rosensis is a hybrid between the fall-leafed hybrid above, Lycoris x rosea and the spring-leafed Lycoris chinensis.
Lycoris x rosensis ‘Colorama’Lycoris x rosensis ‘Three Towers Mirroring the Moon’
Lycoris x sprengensis is a cross between the spring-leafed Lycoris sprengeri and the spring-leafed Lycoris chinensis. The flower buds almost all show a blue tip, whose color disappears as the flowers age.
Lycoris x sprengensis ‘Lemon Cheescake’
Lycoris x straminea is very similar in appearance to Lycoris x albiflora. The only difference between the two is that one parent of Lycoris x straminea is the spring-leafed Lycoris chinensis instead of the fall-leafed Lycoris aurea. Interestingly, Lycoris x straminea is fertile, while Lycoris x albiflora is not. Because Lycoris x straminea is fertile, it can be crossed back onto its Lycoris radiata parent, created some stunning orange-hued flowers
Lycoris x straminea ‘Caldwell’s Original’Lycoris x straminea ‘Gennen’Lycoris x straminea ‘Peach Chiffon’
Most Lycoris x straminea clones open pure yellow, and acquire a reddish-orange blush as they age, from the Lycoris radiata parent. You can see an example below with two images taken 2 days apart.
Lycoris x straminea ‘Peach Taffy’Lycoris x straminea ‘Peach Taffy’Lycoris x straminea ‘Strawberry Lemonade’
Lycoris ‘Peppermint’ is an old passalong hybrid of two spring-flowered species, known and sold as Lycoris x incarnata…a cross of Lycoris longituba and Lycoris sprengeri. Our studies, however have shown that this plant could not have arisen from such a cross. In hybrids between a spring and fall-leafed species, the offspring always has foliage that emerges in early fall (September, October). The foliage on this emerges in late November, and the only way this could happen if the hybrid included 2 spring species and 1 fall species.
The only species that could provide the red color is the fall-foliage Lycoris radiata and the only species which could contribute the white color is Lycoris longituba. The other parent must be a spring-foliage species, so the only option is Lycoris sprengeri. We now feel confident that this hybrid could only have occurred with a cross of Lycoris sprengeri x radiata x longituba. We call these hybrids, Lycoris x longitosea (longituba x rosea).
Lycoris ‘Peppermint’
To determine which lycoris will thrive in your hardiness zone, simply look at when the foliage emerges. The fall-foliage species/hybrid are best from Zone 7b and south, although some will grow in Zone 7a. The spring-foliaged species/hybrids should be fine in Zone 5, and possibly as far north as Zone 3.
While lycoris will grow and flower in sun, they perform far better in filtered deciduous shade, where the foliage will have some protection from the ravages of winter. The amount of light they receive in summer when they have no foliage isn’t really relevant to their performance.
It’s always exciting for us when the summer flowering surprise lilies begin to bloom, which usually happens here around mid-July. Lycoris are members of the Amaryllidaceae family, and are cousins of better-know bulbs like hippeastrum (amaryllis), zephyranthes (rain lilies), and narcissus (buttercups).
Since we grow over 700 different lycoris varieties, the flowering season goes all the way from now into October. Below are are few of the early varieties from the start of the flowering season.
Lycoris longituba ‘Buttercup’Lycoris sprengeri ‘Julyza’Lycoris x sprengensis ‘Magic Rainbow’Lycoris x sprenguinea ‘Matsuribune’
In our cold frames, some plants will occasionally flower out of season, and that’s the case this week when one of our Orostachys ‘Crazy Eddie’ plants decided to flower out of season…fall is it’s normal time. The offseason timing won’t adversely affect the plant, and it did give us an unexpected photo moment. Because of the form of the flower, orostachys gained the common name, dunce caps, named after the pointed caps that poorly performing students were forced to wear. Of course, you’re probably showing your age if you knew what dunce caps were.
