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.
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.
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.
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’.

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.
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 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.
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.
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.
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.
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.
Acis ionicum in the crevice gardenClose up of Acis ionicum
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.

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.
It’s hard to imagine a plant more obscure that the Southeast coastal native Houstonia procumbens. You may recognize the name houstonia as belonging to one of the many more common bluets. Instead, this is a creeping white-et. We’ve had this in our alpine rock garden for a couple of decades, but barely notice it until November, when the flowering picks up as other plants around it are going dormant. In the wild, Houstonia procumbens can be found in moist pine savannahs as well as nearby disturbed habitats. We’re unsure if this is showy enough for anyone to actually purchase.
Most gardeners in mild winter climates are familiar with Liriope (monkey grass), and Ophiopogon (mondo grass), but almost no one is familiar with the third cousin, reineckea (false lilyturf). Like both better known cousins, reineckea is an evergreen groundcover, but unlike the others, here is our clump of Reineckea ‘Little Giant’ in full flower for Thanksgiving. Depending on your taxonomist, there is between 1-3 species in the genus. We’re certain of three and think there may be more. We have assembled a collection of nearly 30 wild collections and will be working with other researchers to sort out the taxonomy of this group.
The splendid, giant-growing Salvia madrensis ‘Redneck Girl’ is a JLBG introduction and has been at peak the last few weeks. This is so superb for climates where you can avoid an early fall frost.
In flower now in our parking lot beds is our amazing 2005 introduction, Gladiolus ‘Halloweenie’…a fall-flowering, seasonally colored selection that we just adore.
One of our favorite fall woodland plants is a member of the Aster family, belonging to the genus farfugium. Farfugiums have long had a bit of an identity crisis, as they were originally named in 1767 by Linnaeus as Tussilago japonicum. In 1768, the same plant was also published as Arnica tussilaginea. Then, in 1784, it was moved to the genus, senecio, and became Senecio japonicus.
Later in 1891, it was renamed again, this time as Seneciotussilagineus. It remained in the genus senecio until 1904, when it moved to the genus Ligularia, and became Ligulariatussilaginea. Here it remained until 1939, when it became Farfugiumtussilagineum, but corrected the same year to match Linnaeus’s original epithet, resulting in Farfugium japonicum, which it remains today.
Below is our plant of the typical species, Farfugium japonicum in flower at JLBG this week. Through the decades, we have been collecting an array of other forms. Light open shade or a tiny bit of morning sun and average to slightly moist soils produce the best results.
Farfugium japonicum
Farfugium ‘Roundabout Fall’ is our selection of a hybrid with our Taiwanese collection Farfugium japonicum var. formosanum and the typical form. We like the smaller, thick, rounded leaf shape.
Farfugium japonicum ‘Roundabout Fall’
Farfugium ‘Jagged Edge’ is another upcoming JLBG/PDN introduction, scheduled for a 2023 release. It forms one of the larger clumps of any farfugium cultivars we’ve grown.
Farfugium japonicum ‘Jagged Edge’
Farfugium ‘Bashi Ogi’ is the only cultivar we know of Farfugium japoncium var. luchuense. This rare variety hails from Japan’s southern Ryuku Islands of Okinawa and Kagoshima. It differs in appearance by being a much smaller plant with leaves which are wider than tall. Here is our plant flowering now here at JLBG.
Farfugium japonicum ‘Bashi Ogi’
For 2022, Plant Delights will introduce JLBG’s first selection of Farfugium japonicum var. luchuense, that we’ve named Farfugium ‘Sweet Spot’. It’s a miniature seed selection from the above Farfugium ‘Bashi Ogi’, that only gets a few inches tall, so will make a great house plant, where it isn’t winter hardy.
We’ve been experimenting to see how many species of asclepias will survive in our climate, and one that has been quite fascinating is Asclepias subulata. This odd species from the southwest deserts of the US has evergreen glaucous stems, and not much in the way of leaves. It will be quite interesting to see what the butterfly larvae actually consume. It did flower for us this fall for the first time. This will be our first winter, so fingers crossed it can take our cold and wet temperatures. We sited this on a slope in one of our crevice gardens, so it wouldn’t drown in our summer rains.
Salvia regla ‘Jame’ (pronounced Haam-hey) is looking so wonderful this time of year. This amazing North American native (US/Mexico) was originally shared back in 2000, by the late Salvia guru, Rich Dufresne. It has adorned our gardens every year since with these amazing fall shows. Hardiness is Zone 7b and warmer.
There are few plants that put on a better fall show than the amazing Eupatorium havanense, now known as Ageratina havanensis. This oustanding Texas native is flowering now, having burst into flower in early November, providing nectar for a wide variety of insects, and great floristic enjoyment for a wide variety of gardeners. Plant Delights offered this for a number of years, but sadly, few people could be enticed to purchase one. Hardiness is Zone 7b and warmer.
Looking particularly good this week is one of the Southeast US (NC to Texas) native water orchids, Habenaria repens. This gem flowers through most of the growing season, and hasn’t slowed down as we enter November. Water spider orchid can grow both as a marginal or as a true aquatic. Our plant is growing in one of our crevice garden seeps. We’re working to get this really cool native propagated and available in the future.
About the same time that America’s Captain Kirk blasted off into space recently, we were enjoying his namesake here in the gardens at JLBG. Crinum kirkii is a fantastic dwarf crinum lily to only 18″ tall, that is sadly almost never seen in commerce. Full disclosure…Crinum kirkii was actually named for botanist Sir John Kirk, who found and sent this previously undescribed species from his outpost in Zanzibar to Kew Gardens in 1879.
Crinum kirkii has thrived for us here in Zone 7b since 2012. Our plants of this African species are from Tanzania. Perhaps one day, we can produce enough of these to share.
Flowering this week is the amazing Southeast native subshrub, Clinopodium georgianum. The leaves have a wonderful fragrance of strong peppermint, and the flower show isn’t bad either. This is Zac/Jeremy’s collection from Henry County, Alabama.

A carpenter bee working nearby stopped in for a floral snack.
Looking lovely in the garden is week is Gossypium thurberi ‘Mt. Lemmon’…our introduction of one of the progenitors of modern day cotton. On a 2005 botanical expedition, we discovered this North American native perennial hibiscus relative, known as Desert Cotton, growing in the mountains of Arizona. In the garden, it’s a superb flowering machine for late summer and early fall. Winter hardiness is probably Zone 8a and warmer.
Here is a future introduction for Plant Delights, a 2018 Wilkes County, Georgia collection of a dwarf, compact form of our native frost aster, Aster pilosus (Symphyotrichum pilosum), collected by our research staff, Zac Hill and Jeremy Schmidt. It’s looking rather impressive in the trial garden this week, 30″ tall x 5′ wide.
We’ve really enjoyed the show of the native rigid golden rod this fall, aka: Solidago virgata ‘Golden Voice’. Our plant is growing in our pitcher plant bog.
Aster oblongifolius ‘Fanny’ (Symphyotrichum oblongifolium) has put on its normal superb show this fall. Keep in mind that this gets quite large. This is a 2 year old plant from a quart pot, which has already reached its mature size of 8′ wide.
Lespedeza ‘Little Volcano’ puts on quite a show each fall. Here it is in the garden this fall in full bloom. This amazing dieback perennial reaches an amazing 7′ tall x 15′ wide in good soils and full sun. Our friend Ted Stephens is responsible for bringing this gem from Japan to US gardeners.
To most folks, especially car collectors and gearheads, Hemi’s refer to hemispherical combustion engines, but to those of us hortheads, Hemi’s refer to a group of gesneriads (African violet relatives) in the genus Hemiboea. We started growing the fall-flowering hemiboeas in the early 1990s, thanks to Atlanta gardeners, Ozzie Johnson and Don Jacobs, both of which were horticulturally way ahead of their time.
Our hemiboea collections are now up to six species that have survived in or climate, including two new gems that are flowering now. Hemiboea subacaulis var. jiangxiensis came from a joint JC Raulston Arboretum/Atlanta Botanical Garden Chinese expedition.

Hemiboea strigosa is a gem we picked up on a UK nursery trip in 2020 that’s also performed very well here at JLBG. All hemiboeas prefer light shade and average to moist soils. Winter hardiness is still to be determines, although some members of the genus have thrived as far north as Zone 6.
Our favorite fall-flowering legume is looking fabulous now. While most daleas (baptisia cousins) flower in spring and summer, only one that we’ve grown waits until fall to produce its amazing floral show. Dalea bicolor var. argyraea is an easy-to-grow species, found in the dry alkaline sandy soils of Texas and New Mexico. Here at JLBG, it has thrived everywhere it’s been planted…all dry, un-irrigated beds. Native pollinators love it also.
Some new plants are flashes in the proverbial pan, while others become long term industry standards. Here is our patch of Solidago rugosa ‘Fireworks’ in the garden this morning. This 1993 introduction from the NC Botanical Garden and Niche Garden has still not been topped 28 years later…one of the most stunning and best performing perennials we’ve ever grown.
