We thought we’d share a photo taken this week of the original plant of Illicium parviflorum ‘Florida Sunshine’ from our garden. All plants sold worldwide originated with cuttings taken from our specimen. The original plant has now been in the ground here for 22 years and measures 8′ tall x 8′ wide. The foliage becomes brightest in the cool temperatures of winter. Who says Southeast US native plants look ugly? Hardiness zones 6a to 9b.
Our 13 year old clump of the evergreen Japanese Asarum asperum is looking superb in the garden this week. Looks like it’s about time to divide this for the first time and start to build up stock so we can share in the future. Winter hardiness is Zone 6-9.
We hope everyone has had a chance to check out the new 2023 Plant Delights catalog, now online. Our greenhouse are fully stocked with plants we hope will appeal to the gardeners in our audience….see photos below taken this week.
Our market has always been a bit different that other mainstream mail order nurseries, first because we grow and produce virtually all of our own offerings. That allows us better control over quality, trueness to name, and availability. Our on-line offerings are currently just over 1000 items, of which over 300 are Plant Delights/Juniper Level Botanic Garden introductions or exclusives.
A first cousin to the better known aroid, arisaema is the lesser known aroid, arisarum. While arisaema has a distribution that is primarily North American and Asian, arisarum is primarily European. We planted our first arisarums back in 1994, and since then have tried quite a few and killed quite a few. The best species for our climate is Arisarum vulgare, a Mediterranean native, found naturally in the countries of Albania, Algeria, Baleares, Corsica, Crete, Cyprus, East Aegean Islands, France, Greece, Italy, Lebanon-Syria, Morocco, Palestine, Sardinia, Sicily, Sinai, Spain, Transcaucasus, Turkey, and the former Yugoslavia.
With such a wide range of occurrence, some forms are naturally going to be more adaptable to our Zone 7b climate than others. The star in our trials has been a 2010 Crete collection of Arisarum vulgare from near the town of Lakki. From a tiny rhizome piece, it has spread to a 3′ wide patch. Like its’ other cousin, arum, arisarum goes summer dormant, re-emerging in fall. All of the previous forms of Arisarum vulgare we’ve grown have flowered only in early spring, but this amazing form flowers quite well every fall, in addition to being incredibly vigorous. We’ve just dug some of our patch today, and will work on propagating them for a future PDN catalog under the name Arisarum vulgare ‘Lady Lakki’. Hardiness is Zone 7b and warmer.
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.
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.
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.
Our 2016 century plant hybrid is looking quite lovely in the garden this month. This plant, which we named Agave x victorifolia ‘Prince of Whales’, is a hybrid of the Whale’s tongue century plant, Agave ovatifolia (male parent), and the Queen Victoria century plant, Agave victoriae-reginae (female parent).
Since both parents are non-offsetting, this means that the offspring will grow to maturity, flower, then die. Consequently, in order to be able to propagate and share, we will have to drill out the central core of the plant to trick in to offset. While this ruins the appearance of the original, it’s the only way for this to ever be shared and preserved. This plant has been in the ground since 2018, so we expect to have another eight years (guessing) prior to flowering. Consequently, so we’ll probably gamble on waiting a few more years before performing surgery. Winter hardiness is Zone 7b-10b.
Below is a photo of both parents.
Carex ‘Willow the Wisp’ is one of Zac Hill’s amazing collections from nearby Willow Springs, NC. This is a widespread native, naturally ranging from Michigan south to Florida and west to Texas. We love the appearance of a head of green hair…minus the head. In the wild, this selection of Carex leptalea var. harperi thrives in wet mucky swamps, like the story of Will-o’-the Wisp. We planted this in similar conditions in a seep at JLBG, where it has made this stunning specimen. Any plant that looks this good in October is undoubtedly destined for a future catalog.
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.
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 ‘Harry Hay’ seems to be the only named clonal selection grown in the UK. We imported this during our 2020 UK trip.
Rhodophiala bifida ‘Carmencita’ is our first named introduction, released in 2017.
Rhodophiala ‘Red Waves’ is our 2nd named selection, not yet introduced
The rest of the clones below are our selected seedlings still under evaluation
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.
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.
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.
Re-appropriating a line from the late Buck Owens, it’s crinum time again. Crinum lilies begin their flowering season in our climate around April 1 (frost permitting). Some bloom for a short number of weeks, while other rebloom for months. Depending on the genetics, some crinum hybrids start flowering in spring, some in summer, and others in fall, and a few flower during the entire growing season.
Crinum ‘High on Peppermint’ is one of our newer named hybrids, which starts flowering for us around June 1, and hasn’t stopped yet.
Crinum ‘Superliscious’ is another of our new hybrids that starts flowering July 1, and has yet to stop. Now that our evaluation process is complete, we’ll start the propagation process.
Crinum ‘Southern Star’ is an incredible hybrid from the late Roger Berry, entrusted to us to propagate and make available. That’s a tall order since it’s one of the slowest offsetting crinum lilies we’ve ever grown. Crinum ‘Southern Star’ is a hybrid with the virtually ungrowable, yellow-flowered Crinum luteolum, which hails from Southern Australia. For us, Crinum ‘Southern Star’ doesn’t start it’s floral display until August 1.
Tired of trying to grow the conventional baby’s breath, that’s a prize perennial in the colder zones? We were, and had been looking for a substitute for years, when in 2000, one of our former staffers introduced us to the widespread native, Euphorbia corollata. Although it doesn’t look like much in deep shade where it’s often found in the wild, it explodes when given a bit of sun. Here are a couple of photos as it’s flowering season starts in mid-July.
Euphorbia corollata looks seriously gangly in a pot, so we’re confident you’ll never see this on the shelves of the box stores. Average moisture to very dry suites it fine. Although not a clumper, it’s spread it’s far from a thug, and is easy to remove it it happens to move too far. For a plant that’s native to every state East of the Mississippi (except Florida), and almost every single county, it’s shocking that every gardener isn’t growing this gem. Hardiness is Zone 3a-9b.
This spring, Plant Delights introduced Zac Hill’s 2013 discovery of a new ruellia which he found in central Alabama. What we theorized might be a natural hybrid turned out to be a brand new species, as we were informed by botanists working on getting the plant published. We hope all native plant enthusiasts purchased this to both enjoy in their garden and for ex-situ (off site) conservation value. These are in full flower during the summer. Hardiness is unknown at this point, but we know it’s fine from Zone 7b – 8b, and most likely much further north.
One of our favorite love lilies in our 2003 introduction, Amorphophallus konjac ‘Pinto’. This amazing dwarf never has foliage that exceeds 16″ in height. Unfortunately, the ridiculously slow growth rate has kept us from offering it again since, but perhaps one day. Here is our parent plant in the garden this week. Even if you don’t have a home garden, this form is superb in a container. We had a large crop of dwarfs from seed two years ago, and are looking for more unique new compact selections.
Our OCD is on full display with many of our plant collections including the summer-flowering Crinum lilies. Our collections here at JLBG have now topped 400 crinum taxa. In addition to collecting the best plants from other breeders, we have also been making a few of our own selected hybrids. Below are a few photos of plants we have recently selected and named. None of these are available yet, and most will still be a few years away, while we build up enough stock to share.
If you’ve never grown crinums (first cousin of hippeastrum), they form huge bulbs, and thrive in full sun in average to moist soils.
We often hear and read that hostas won’t grow well in the mid and deep south, so we thought we should share a few garden photos from this week at JLBG (Zone: 7b), to bust yet another garden myth.
Starting with some small/miniature hostas, the first is Doug Beilstein’s Hosta ‘Baby Booties’, a superbly vigorous dwarf that has really been exceptional.
Hosta ‘Blue Fingers’ is a PDN/JLBG introduction of one of the very few tiny blue-leaf hostas with excellent vigor and a good multiplication rate.
Hosta ‘Wriggles and Squiggles’ is an exceptionally wavy-leaf, small, gold introduction from plant breeder, Hans Hansen.
Hosta ‘Fire and Ice’ is another Hans Hansen introduction that was a reverse sport of Hosta ‘Patriot’. It fares much better when given more light, even a few hours of sun in the morning.
Hosta ‘Swamp Thing’ is a PDN/JLBG introduction with great vigor and glossy foliage
Hosta ‘Beyond Glory’ is a Hans Hansen sport from Hosta ‘Glory’. This is just one exceptional hosta, which also benefits from a bit of morning sun or very open shade.
Hosta ‘Diamond Lake’ is a stunning new Hans Hansen creation with large blue corrugated leaves with exceptional leaf rippling.
Hosta ‘Gold Meadows’ is one of our favorite sports of Hosta sieboldiana ‘Elegans’. When the weather warms, the central pattern fades to solid blue, but in spring, it’s absolutely stunning. It has also shown great vigor in the Southeastern US.
Hosta ‘One Last Dance’ is a Hans Hansen/Walters Gardens sport of Hosta ‘Dancing Queen’. We think it’s hard to beat this amazing plant. The vigor is evident in our photo.
We love all of our trout lilies, but Erythronium ‘Goldstrike’ is hard to beat. This is our named selection of Erythronium americanum ssp. harperi. Occurring from Tennessee south of Mississippi, this amazing form graces low woodlands in very early spring. This collection was made by our Plant records/taxonomist, Zac Hill in Alabama. Hardiness is Zone 6-9 at least.
I had a great visit recently with David Cain and Denny Werner. Most of you know Dr. Werner from his work at NC State, first as a peach breeder and later as the creator of a parade of amazing redbud hybrids.
David and Denny were both grad students together back at Michigan State. Dr. Cain went on to become a fruit breeder, and is the papa of the incredibly famous Cotton Candy grape. On the off chance you haven’t tried it, be sure to search for it at your local grocery store. David worked in academia and later the USDA, before embarking on his own venture, where he made several incredible fruit breeding breakthroughs.
I didn’t realize David is a long-time plant nerd and Plant Delights customer, and has recently moved from California to the East Coast for his next plant breeding adventure. We had a blast talking plant breeding and looking at a few of our crazy breeding projects at JLBG.
One of the fun reasons to grow plants from seed is that each seedling is different…unless you’re growing highly bred annuals. Most non-hybrid seedlings will be under the bell curve, meaning they all look and behave relatively similar. As plant collectors, we get excited when one appears that falls outside the bell curve. An example is our wild ginger selection, Asarum maximum ‘Floragasma’, which has both far more flowers than we typically see with the species, but it also flowers 2-3 weeks before our other clones. Winter hardiness is Zone 7b-9b.
The first plant looks for all the world like a fine textured carex, but in fact, it’s an iris. Iris dabashanensis is a little-known species from China, that thrives for us in light shade, but will also take a few hours of early morning sun. Our plant is a Darrell Probst collection from Sichuan, China. Winter hardiness is Zone 5a -8a.
Below is the same plant flowering in early April.
The other plant growing nearby in our gardens that fools even the keenest plantsmen is this liriope look-alike. In fact, this is a cast iron plant, Aspidistra linearifolia. This demonstrates why those pesky taxonomic traits matter. In 2008 we introduced a selection with a lighter central stripe down the center of each leaf called A. linearifolia ‘Skinny Dippin’ which we will be offering again in 2023. Winter hardiness is Zone 7b and warmer.
This winter has been an amazing one at JLBG for the mid-winter flowering, evergreen magnolias. Formerly known as Michelia, there are several species from warm temperature Asian climates, which flower in the mid-winter. The plant in the top photo is our oldest specimen of Magnolia platypetala, and below is Magnolia macclurei…both planted in 1999, and in full flower in January. Obviously, we will loose open flowers if winter night temperatures drop too far below freezing, but the remainder of the flower buds usually open shortly after temperatures warm.
Also, the bright gold shrub in the first image is the original plant of our introduction, Illicium parviflorum ‘Florida Sunshine’…the plant from which all plants in the world were propagated. To the lower right is the Mediterranean native, Phlomis fruticosa ‘Miss Grace’. All in all, a lovely winter garden combination.
It’s always interesting when we introduce a plant we think is an incredible addition to the garden, but virtually no one purchases it. Thank goodness, it doesn’t happen too often, but I’m reminded of one such case every day when I get home and admire our row of Agave x striateosa ‘Straight and Narrow’. This 2015 introduction was the first ever hybrid introduction of Agave bracteosa and Agave striata…both non-spiny century plants.
We couldn’t stand to throw out all the plants that didn’t sell, so we planted a row under a wide overhang along our home, where they never see any water, and are in shade for more than half the day. Here is one of those plants five years later, providing a texture and form that you simply can’t find with any other plants that tolerates those conditions.
We have a second seedling from the same cross, which we’ve never been able to share, but which flowered in 2015. Despite our best attempts, we were not able to get any seed set. Now, we await the first flowering of this clone in the hopes it is more fertile, so we can create some more unusual hybrids. Unlike most century plants, Agave striata is not monocarpic (doesn’t die after flowering), so we expect this hybrid to also live on in perpetuity after flowering. Winter hardiness is Zone 7b-10, at least.
One of many exciting new introductions for 2022 is Phlox divaricata ‘Blue Ribbons’ PPAF. This variegated version of our wonderful native woodland phlox was discovered here as a single sport in our garden by our plant taxonomist, Zac Hill. Instead of being all green, each leaf is edged with a wide creamy border and flushed with pink during the colder months. In early spring, the entire clumps are topped with sweetly fragrant blue flowers. We think Phlox ‘Blue Ribbons’ is an incredible design addition for the woodland garden. Hardiness is Zone 3-8. The new catalog, with this and many other amazing gems, goes on-line in 2 weeks!
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 Senecio tussilagineus. It remained in the genus senecio until 1904, when it moved to the genus Ligularia, and became Ligularia tussilaginea. Here it remained until 1939, when it became Farfugium tussilagineum, 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 ‘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 ‘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 ‘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.
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.
Another genus of ferns that we just adore are the bamboo ferns of the genus coniogramme. We’ve grown these amazing gems for two decades, and after all that time are still in love. Although these woodland ferns are deciduous, they are tardily so, so they still look quite fresh into mid-November. Here are a couple of favorites, photographed this week.
At the top is the texturally fascinating Coniogramme intermedia ‘Shishi’ from Japan, and below this is our 2006 introduction of the Chinense native Coniogramme emeiensis ‘Golden Zebra’. We rate both of these as winter hardy from Zone 7b 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.
Sinningia ‘Pink Pockets’ was a Plant Delights/JLBG introduction in 2011…a hardy gesneriad that had thrived in our in ground trials. Here it is this week, planted in 2005 and still performing superbly in part sun. We love plants that stand the test of time in the garden.
We have a rather large collections of crinum lilies at JLBG and occasionally take time to make a few crosses. One of our recent selections is one we’ve named Crinum ‘Delerium’. Flowering again this week, this is a cross of Crinum variabile and Crinum bulbispermum, meaning it should be winter hardy in Zone 6. We re just dividing our original clump for the first time, so it will take a few years to get enough to share, but the process has begun.
Here’s a recent combo at JLBG with Eucomis comosa ‘Sparkling Burgundy’ (our first plant introduction), paired with Hemerocallis ‘Prize Picotee Splendor’ (introduced by our friend Roy Klehm), and backed with Lagerostroemia faurei ‘Townhouse’, an introduction from our mentor, the late J.C. Raulston. For us, it’s about the plants and the people!
We had failed miserably at keeping the true blue-flowered forget-me-nots, Myosotis, alive in our heat and humidity until our friend and gardening legend, Pam Harper shared this amazing heat tolerant form with us in 1994. We subsequently named it M. ‘Southern Blues’. It has thrived as both a marginal aquatic and in regular garden soils, where it makes a superb non-weedy, groundcover. In over 25 years, we’ve never seen a single seedling. Here it is in the gardens at JLBG this week.
There’s a reason hostas are the #1 perennial in the US. The incredible diversity of leaf shapes, sizes, and colors are one, combined with the array of climates in which they thrive. It’s long been rumored that hostas don’t grow well here in Zone 7b, but that simply isn’t the case if you prepare your soil properly (lots of compost) and allow for plenty of summer moisture.
Below are a few hosta cultivars that are looking particularly nice this week at JLBG. Of course, the proverbial deer-in-the-room is that hosta make quite the tasty buffet for both humans and wood rats. Deer fences and organic sprays all work, but the breakthrough will come when CRISPR technology is used to implant the Capsaicin (pepper) gene in hostas, rendering them too hot for most deer.
Here are a few of our favorites this week. Hosta ‘California Gold Rush’ has shown incredible vigor.
Love the over-the-top waviness of Hosta ‘Wheee!’
Hosta ‘One Last Dance’ has it all…vigor, size, ruffles, a nice flower show, and great leaf coloration. Did I mentioned that it’s also very sun tolerant if the soil is moist?
Hosta ‘Coast to Coast’ is also very sun tolerant with amazingly corrugated leaves and great vigor on a fairly large clump.
Hosta ‘Do Wap’ is one of our yet to be introduced hybrids from our work to create blue hostas that hold the color well into the summer.
Hosta ‘Pie ala Mode’ didn’t get a lot of fanfare when it was introduced, but this has been exceptional in our gardens at JLBG. Hope these entice you to explore this amazing genus.
Agave x striphantha ‘Striptease’ is a JLBG creation from a 2013 cross of Agave striata and Agave lophantha. Both parents are 30 year survivors here in the garden, so we wanted to see what a combination of genes looked like. Also, Agave striata is the only hardy agave species, whose main crown doesn’t die after flowering. So far, this gem is 3′ wide, and like the Agave striata parent, it offsets from the crown and doesn’t sucker like Agave lophantha. It’s looking like a flower spike may be imminent, so perhaps we’ll have our flowering question answered soon.
We just snapped this photo of our 2006 Hosta introduction, H. ‘Swamp Thing’, looking quite divine. Sadly, this was one of those plants that just didn’t sell well, which is a shame, since we think it’s one of our best hosta introductions in terms of both vigor, and visual interest. We named it after the Creature from the Black Lagoon, since the foliage is so shiny, it looks like it just emerged from being under water. Hard to figure out the buying public sometimes.
