The Grape Savant

I recently had the opportunity to visit the grape breeding trial garden of grape savant, Jeff Bloodworth of Orange County, NC. I didn’t realize it until my visit that Jeff, now 73, and I were in the Horticulture Department at NC State together from the mid to late 1970s. While I was starting on my undergraduate work, he was working on a Masters and later a Doctorate. After school, Jeff went on to become a Research technician with NC State grape breeder Dr. Bill Nesbitt, until he unexpectedly passed away in 1983 at the age of 51.

Departmental leaders decided to do away with the grape breeding program due to a lack of commercial interest in NC, so Jeff saw an opportunity. Scrambling quickly, he found and purchased 12 acres in rural Orange County, where all the NCSU research genetics found a new home. Jeff, and his wife, Peggy, still live on the same property today.

I’ve grown and studied muscadine grapes for almost 40 years, but Jeff’s little finger has far more knowledge than I dreamed existed. To say Jeff is obsessive about his work with grapes is a grand understatement.

We were joined by video producers Bill Hayes and Erin Upson of Carboro’s Thunder Mountain Media, who are working on a video project to help tell Jeff’s amazing story.

Until 2013, Jeff had never introduced a single new grape. Part of the reason is that his breeding goals were regarded as impossible “pie in the sky” ideas. Jeff was trying to cross seedless bunch grapes (pictured below), which grow well in California, but sulk in our summers, with the Southeast US native muscadine grapes.

California bunch grapes in NC

After 10 years of no success, he finally was able to secure a viable offspring, and so was off to the races. Despite this eventual breakthrough, Jeff struggled to get any commercial or academic entities interested in his creations.

That was until plantsman and Gardens Alive owner, Niles Kinerk and his team, heard about Jeff’s work, and soon after, hired Jeff as an employee, providing some welcome financial support. Below are Jeff and Peggy Bloodworth with Mark Wessel, Gardens Alive Director of Horticultural Research.

Jeff’s first introduction through Gardens Alive, in 2013, was the light purple Vitis ‘Razmatazz’. This small-sized grape was the first seedless muscadine hybrid on the market. Although the fruit size is small by conventional standards, it is long producing as well as deliciously sweet. This was followed a few years later by Vitis ‘Oh My’, a bronze fleshed, larger seedless muscadine hybrid.

My trip last week was to join the Gardens Alive team as they sampled the new hybrids and made their final selections for future introduction. I was particularly excited by one of Jeff’s hybrids with 1″ seedless bronze grapes, but Jeff explained by slicing the grape in half and examining the ovary, that this was a female grape, which would need a male pollinator. Most commercial muscadine varieties are “perfect”, with both male and female flowers on the same plant. The size of Jeff’s seedless grapes continue to increase, and the variance of sweet flavors are astounding, so the future of grapes in the Southeast US is very exciting.

Nearby Jeff’s farm, investors have purchased much of the regional farmland with the goal of large scale production, including hundred of acres of Jeff’s grapes. We salute Jeff’s brilliance and persistence in this amazing endeavor!

Another Summer Snowstorm

Looking and smelling wonderful in the garden this week is our 2022 introduction, Hosta ‘Summer Snowstorm’. We love late-flowering hostas with large fragrant flowers, and this one doesn’t disappoint, with foliage that still looks great in late summer.

Summer visit to Spring Meadow

On a recent trip to Michigan, I made my first stop at Spring Meadow Nursery in Grand Haven. Most homeowners may not have heard of them, but Spring Meadow is a liner producer of shrubs, primarily for the Proven Winners branded program. If you buy a shrub from a retailer in a PW white pot, it came from Spring Meadow.

Spring Meadow was begun by Michigan State graduate Dale and his wife Liz, in 1981, after Dale finished a stint with the now defunct mass market wholesaler, Zelenka Nurseries. Since that time, they have become the dominant player in the wholesale liner market, especially for the Northern tier of states.

Spring Meadow Nursery

Below are the folks responsible for all the perennials and shrubs in the PW program. Dr. Judson Lecompte (l), and Tim Wood (c) – shrubs, and Hans Hansen (r) of Walters Gardens – perennials.

Their headquarters, which gives the feeling of a large barn is recent construction, after a 2017 fire burned their entire offices to the ground. The rebuilt offices include all the typical admin features, but also includes a classroom where wholesalers and retailers are taught about their plants.

Spring Meadow classroom

The sheer number of plants produced here is staggering, as you can see below.

There are so many plants that simply tasks like pruning becomes monumental. To solve that problem, hedge clippers are mounted on a trolley, which automatically traverses the greenhouses.

In 2019, Spring Meadow purchased mail order retailer, Great Garden Plants, from co-founder, Mary Walters. This became Spring Meadow’s retail outlet for their introductions. Below are the sections of the production greenhouse devoted to inventory for GGP.

Still Mad about Mangaves

Just back from the center of xMangave breeding at Walters Gardens in Michigan. xMangave are mesmerizing hybrids between Manfreda and Agave. Here are a few photos from the display garden there.

Summer Carnival

The variegated hardy hibiscus, H. ‘Summer Carnival’ has looked outstanding all summer. This Hans Hansen creation has both variegated leaves and flower buds. We’ve had these in the garden since 2017, and they continue to excel. Moist to wet soils and full sun are ideal, but they handle short term drought just fine. Hardiness is Zone 4a-9b.

Surprise, Surprise, Surprise

It’s that time of year, when the surprise lilies, Lycoris, that we have scattered throughout the garden begin to pop. Actually, due to our early summer rains, they began popping in early July this year, 2-3 weeks ahead of normal.

Surprise lilies are divided into two groups, based on when their leaves emerge….fall (October) or late winter to early spring (March). Those with fall emerging foliage are generally not winter hardy north of Zone 7a, while those with late winter to early spring emerging foliage can usually tolerate temperatures of Zone 4/5.

Here are a few recent images from the garden from our world-renown collection of 1,090 different selected clones. The spring-foliaged hybrid, Lycoris x squamigera is the most popular clone, and be seen in gardens from Minnesota south.

Lycoris x incarnata ‘Blue Queen’ is another spring-foliaged hybrid that’s yet to hit the market.

Lycoris x incarnata ‘Blue Queen’

Lycoris x straminea ‘Caldwell’s Original’ is a hybrid of the late Sam Caldwell, who is one of the first breeders who devoted his life to understanding the genus Lycoris. This is a fall-foliage emerging hybrid.

A Breed Apart

Plant breeding is a wonderful hobby that attracts an array of hobbyists, as well a plant professionals. Many plants, such as hemerocallis, hosta, hibiscus, and iris, are so easy that they attract the majority of hobbyist breeders. Professionals and the craziest of the breeders occasionally focus on more difficult plants that few others are willing to try. This includes plants where the pollen exchange is complicated either by timing, incompatibility, or other constraints. Such is the case with century plants (agave).

Peak flowering season for 2023 is drawing to a close at JLBG, while one new agave is just in mid-spike. We only had 13 different agaves flower this year, compared to 18 last year. Fortunately, we are able to save and store pollen in the refrigerator, where it will remain viable for at least 5 years.

Below are a few images of Steve Guptill of our garden staff, as he made crosses last week. At the bottom of the first image is our volunteer agave specialist, Vince Schneider, who is training Steve to make the crosses.

With agaves, the process involves waiting for the stigma to become sticky–a sign that it’s receptive to the pollen. Pollen is then gathered from our prospective father and then hauled up the 21′ ladder to the waiting stigmas. Not only are you high in the air, but you’re working around hundreds of bees that are busy gathering copious amounts of nectar.

Assuming we get seed set, they should be ripe by late September/early October.

Both spiking agaves in the photo below are our selected hybrids from previous years breeding.

Where are they now? Sparkle deVine revisited

Those who were heavily into gardening in the early 1990s probably remember the micro-mail order nursery, The Wildwood Flower, run by the unique and colorful NC plantsman Thurman Maness. While Thurman’s nursery lasted less than a decade in the mail order realm, his impact in the horticultural world continues though his many plant introductions.

Thurman’s probably best known in the plant world for his lobelia hybrids, as demonstrated by his 1990 catalog which listed 20 different lobelias. We’ve offered a number of Thurman’s lobelia hybrids through the years, including varieties like ‘Rose Beacon’, ‘Ruby Slippers’, and ‘Sparkle deVine’, and still carry one of our personal favorites, Lobelia ‘Monet Moment’.

Thurman was also a very successful fern breeder, and many of our favorite ferns today are some of his hybrids like Athyrium ‘Wildwood Twist’ and I still rank his Athyrium ‘Ocean’s Fury’ as the finest fern hybrid ever created.

Athyrium niponicum ‘Wildwood Twist’
Athyrium ‘Ocean’s Fury’

Thurman’s old catalogs also included little known, but garden worthy natives like Scutellaris serrata and the Federally Endangered Silene catesbiae (polypetala). When I first visited back in the early 1990s, Thurman was running his own tissue culture lab, where he was both producing plants as well as conducting ploidy manipulation for breeding..

So, what’s Thurman doing today. At age 87, he’s still working in his garden and propagating plants, which he occasionally sells on site at his Pittsboro home. He tells me that he’s ramping up production because of the new 400 acre development just a few miles away…he’s determined that they all need hydrangeas.

He also still runs his antique business, now from an antique mall in nearby Siler City. When he goes out on the town, he often does so as his alter ego, Sparkle deVine, as you can see in this recent photo below. JLBG/PDN salutes a brilliant plantsman for a horticultural life well-lived.

And Now for Something Completely Different – Pretty Parasols

Plant breeders often get stuck in a rut, copying each other, with only slight variances in each new selection. What makes us stand up and take notice is when a breeder dares to head in a completely different “Pythonian”-like direction. Such is the case with Echinacea ‘Pretty Parasols’, which is in flower now at JLBG. We love this oddity from Belgium’s Jan Spruyt, but am unsure if anyone else will share our excitement. The plant is taller (3′), and much more airy than the form typically seen in other echinacea hybrids. So, what do you think?

Echinacea ‘Pretty Parasols’

The Little Fuchsia that could

Four years ago, we embarked on an experiment to see how well Fuchsia ‘Sanihanf’ would grow in an unprotected hanging basket, left outdoors to the elements all year. The parent species, Fuchsia magellanica is fine in the ground to Zone 6, but has no tolerance of our summer heat.

Fuchsia ‘Sanihanf’ was developed from Fuchsia magellanica and other heat tolerant species, and released in 1997, by the Suntory breeding company of Japan. It has both great heat tolerance, as well as tolerance to our winters when grown in the ground.

Typically, a plant grown in a container above ground loses around 20 degrees F. in hardiness, when the roots aren’t protected, so we weren’t sure how cold our basket plants would survive. The photo below is our basket last week, having now been through low temperatures of: 23F (2019/20), 20F (2020/21), 16F (2021/22), and 11F(2022/23). Although they look like dead sticks until mid-May, they have once again burst forth with great vigor. They are watered through the summer, but receive no supplemental water other than rainfall from fall until spring. We continue to learn amazing things, since we don’t fear killing a few plants along the way in the name of science.

Fuchsia ‘Sanihanf’

The Crinum Show Continues

As we mentioned in a recent blog, we have a ridiculously large collection of Crinum lily cultivars and species. Despite this, we’re always making new crosses in our goal to improve the quality of plants available. Despite their being nearly 1,000 named crinums, there is still dramatic room for improvement. Below is one of our seedlings, which we named last year (Crinum ‘Americana’), erupting in a blaze of glory last week. Most crinum lilies flower for a period of 1-2 months with little to no care, so there’s good value for the space taken. Since the bulbs are so large, it will usually take years to produce and propagate enough of a new introduction to share with the public.

Crinum ‘Americana’

The Crinum King

It was great to get a chance to reconnect with Florida plantsman Nestor White at our recent Open Nursery and Garden, since it had been well over a decade since his last visit. Nestor has what is almost certainly the largest Crinum collection in the world with over 1,000 different accessions. If you purchase crinums on Ebay, you’ve most likely dealt with Nestor. Although we have nearly 400 crinum accessions, we’ll never have a collection as extensive as the one that he’s assembled. Well done!

Nestor White

In Search of Gold

In the crinum lily world, a yellow flower is considered the holy grail by plant breeders, since it only naturally exists in the Australian crinum species, Crinum luteolum. Two other species which occasionally show a yellow blush in the flower are Crinum bulbispermum and Crinum jagus. Crinum luteolum is completely ungrowable in the Southeast US. Consequently, we must find yellow pigment from the other two species.

Many years ago, a secretive California crinum breeder distributed a fuzzy Sasquatch-like photo of what was supposedly his yellow flowered crinum, derived from a white-flowered Crinum bulbispermum. The plant itself has never been seen in person, despite assurances from the breeder that it still exists. In 2008, the breeder agreed to sell us seed from his parent plant, with the caveat that it wouldn’t look like the parent.

Below is the best clone that we selected from our first set of seedlings from Crinum ‘Yellow Triumph’. As you can see, the flower is virtually all white, except for a chartreuse green base. Since it was a nice flowering clone, we gave it the name Crinum ‘White Swans’.

Since 2008, we have repeatedly self-pollinated our original seedling selection, each time selecting those offspring that showed the most yellow color. Over time, the best seedlings were crossed with each other, and the selection process continued.

Crinum ‘White Swans’

Fast forward to 2023…15 years after our original seedling flowered, we finally have plants that are showing a decent amount of yellow in the flowers. The yellow shows best as the flowers open in late afternoon. Below are two of our best 2019/2020 seedlings. While these aren’t yet a finished product, we are seeing the proverbial gold light at the end of the long tunnel.

A Fine Yellow Bird

Our clump of Hans Hansen’s hybrid, Baptisia ‘American Goldfinch’ looked quite outstanding this April. This is a 4 year old clump from a 1 quart pot. Hardiness is Zone 4a-9b.

Desperate Aroids – The adventures of Phallicity

The spring garden at JLBG has a number of phallic moments if you’re lucky enough to catch them. Here are a few of our favorites. Below is a color echo we created, using Pig’s Butt Arum (Helicodiceros muscivorus) and Salvia x nemorosa. We’re sure you’ll want to recommend this combination for everyone in your HOA.

Helicodiceros muscivorus

It’s cousin, Dracunculus vulgaris has also been putting on a show recently. Although the typical red maroon-flowered forms won’t flower for another week or two, the rare white-flowered forms, native only to a small region of Crete, are stunning now.

Dracunculus ‘Spring Bling’ is an Alan Galloway hybrid with a creamy spathe, with a blush purple flush, and black spadix.

Dracunculus vulgaris ‘Spring Bling’

Below is another of Alan’s crosses that we’ve named Dracunculus ‘White Tux’ with a stunning white spathe and contrasting black spadix.

Dracunculus vulgaris ‘White Tux’

Dracunculus ‘White Rhino’ is the most vigorous of all the white-flowered clones we grow. This is yet another Alan Galloway selection, rescued from Alan’s garden, after he passed away at the all too early age of 60 years.

Dracunculus vulgaris ‘White Rhino’

A few years before Alan passed, we were chatting one day about crazy plant breeding projects, and Alan mentioned that he was going to try crossing Arum with Helicodiceros. I told him I suspected he might have better luck crossing Helicodiceros with Dracunculus, since they intuitively seemed to be a better match. He mentioned that both would be in flower in his garden shortly, so he’d be on the case.

Thanks to Alan’s meticulous breeding work, the cross was successful, and three seed eventually germinated. For several years, the foliage of the seedlings looked so similar to Helicodicerous, we both assumed that it was not actually a hybrid. Finally, the year prior to his death, the first of the three seedlings finally flowered, and indeed, he had been successful in creating a bi-generic hybrid, x Helicunculus gallowayii. The foliage, spadix surface appearance, and the flower orientation resembles Helicodiceros. The spathe and spadix are both much longer, the color is more intense and the spathe much more wavy and canoe-shaped, thanks to the Dracunculus parent.

All three seedlings were rescued, but so far, only the original clone has flowered. This week, as it opened, we are once again reminded of Alan’s amazing contributions to the horticultural world, with the flowering of his namesake.

x Helicunculus gallowayii

The Wisdom of Solomon’s Seals

In our spare time, we’ve been playing around with Solomon’s Seal hybrids. This cross of Polygonatum martinii x falcatum is one of the few we’ve found worthy of a name. Polygonatum ‘Winsome Wonder’, flowering now, has long arching stems that reach 6-7′ in length. One day, we’ll have enough of this amazing selection to share.

Polygonatum x marcatum ‘Winsome Wonder’

Flying High with Fairy Wings

The last several weeks have been a floriferous blur in our epimedium collection house. These amazing woodland perennials flower for 4-8 weeks, depending on the variety. Below is a small fraction of the exceptional clones we grow.

Epimedium ‘Rise and Shine’ is a 2020 PDN/JLBG introduction of a hybrid of Epimedium ‘Domino’. The leaves are extremely glossy, and in early spring have a magenta border, along with a great floral show.

Epimedium ‘Rise and Shine’

Epimedium ‘Songbirds’ is our 2014 introduction of an extremely floriferous selection.

Epimedium ‘Songbirds’

Epimedium ‘Pumpkin Pie’ is a potential future introduction with long sprays of large peachy flowers. This is a hybrid of Epimedium wushanense.

Epimedium ‘Pumpkin Pie’

Epimedium ‘Picture Frame’ is one of our later flowering introductions that hit the market in 2014. This has probably the best edged foliage of any fairy wing we’ve grown.

Epimedium ‘Picture Frame’

Epimedium ‘Totnes Turbo’ has been really impressive in our trials. This hybrid from the former UK’s Desirable Plants Nursery, is a cross of Epimedium latisepalum x pinnatum ssp. colchicum.

Epimedium ‘Totnes Turbo’

One of the finest epimediums we grow is Epimedium x versicolor ‘Cupreum’. Although this selection has been around since 1854, it’s still near the top of our list of favorites.

Epimedium x versicolor ‘Cupreum’

Looking you in the eye…the new Lenten Roses

We continue to be impressed with the continuing parade of new selections of sterile lenten roses, in particular, the clones of Helleborus x iburgensis. These fascinating hybrids that originated at RD plants in England, are crosses of Helleborus x ballardiae (niger x lividus) x Helleborus x hybridus. In other words, these hybrids have up to 5-7 different species in each.

Because two of the parents, Helleborus niger and Helleborus lividus, both have outfacing flowers, the flowers on the Iburgensis hybrids all carry that trait. Additionally, most every lenten rose cross with Helleborus niger is effectively sterile. Interestingly, Helleborus niger is the most cold hardy of all lenten rose species, while Helleborus lividus is the least cold hardy, but the most heat tolerant.

Below are a series of photos from the gardens here over the last few weeks of some of the clones we have tried. We find these an exceptional group, many with pink to cream variegation, that should be much more widely grown. Hardiness is Zone 5a-8b, at least.

Fairy Wing Sing Along

Looking absolutely fabulous in the garden now is the superb new fairy wing introduction, Epimedium ‘Lyrical Lemonade’, from the handiwork of plantsman, Hans Hansen. It’s hard to imagine where you’d fit any more flowers. Hardy in zones 5a to 8b.

Epimedium ‘Lyrical Lemonade’

Paramongering in the Greenhouse

Flowering recently in our heated greenhouse was the little-known Paramongaia weberbaureri. This fascinating bulb, native to Coastal Chile at 10,000′ elevation, is a distantly evolved cousin of our native spider lilies, the genus Hymenocallis.

We typically don’t grow many non-hardy plants, but are interested to see if it will hybridize with our native Hymenocallis, since another Andean native, Ismene amancaes, has been successfully hybridized with Hymenocallis in the past. As this is a winter-flowering species, we have collected and refrigerated the pollen while we await Hymenocallis flowers.

Paramongaia weberbaueri
Paramongaia weberbaueri

The Roses of Lent

The earliest of the lenten roses, Helleborus x hybridus, have just opened. Depending on the genetics of each clone, they will continue to open until mid-March. Flowering on each variety continues for many weeks to over a month if the temperatures remain cool. Only a few weeks remain before our Winter Open Nursery and Garden, when you can visit and see these first hand in the garden, and even select your own flowering plants from our on-site nursery, Plant Delights.

Casting Around Seed

We can’t imagine there are many people who grow cast iron plants from seed, but we have found the results quite fascinating. Below are a couple of our seedling which we found good enough to name. Neither has been divided yet, and are still under evaluation, but we think they have good potential.

Aspidistra ‘Bright Lights’ is a 2015 seedling from Aspidistra ‘Okame’ and has a similar variegation pattern, although it has more white banding than its parent.

Aspidistra elatior ‘Bright Lights’

Aspidistra ‘Illumination’ is a 2016 seedling of Aspidistra ‘Sekko Kan’, and inherited the white tips from its mama, but has also pickup up more streaking that wasn’t present in the preceding generation, so perhaps it outcrossed to a nearby streaked parent. If you’re interested in trying this yourself, the seed are found in a 1-2″ wide green ball at the base of the plant now. The seed should be mature in the next 4-6 weeks.

Aspidistra elatior ‘Illumination’

Tough Love Child

We were thrilled to see most of our plants of Trichocereus ‘Love Child’ come through the 11 degrees F unscathed. We hope to have enough of these in the next year or two to share. We had long wanted to grow and offer some of the ridiculously large flowered, tacky colored tropical trichocereus cactus, but they simply had no winter hardiness.

Enter our former volunteer curator, Mike Papay, who had the same idea, but was more determined to make it happen. Mike worked with Trichocereus bruchii, and the resulting second generation plants yielded one he named Trichocereus ‘Big Time’.

He created another winter hardy hybrid using Trichocereus bruchii and Trichocereus thelogonus that he named Trichocereus ‘Iridescent Watermelon’. We subsequently crossed both of Mike’s hybrids together to create a seed strain we named Trichocereus ‘Love Child’. Below is one of our garden plants after enduring 11 degrees F. Below that is the same plant in flower last spring. Hardiness zone 7b to 10b.

Supersize Me

In 2014, we decided our goal for the years’ century plant breeding project was to see how large a Zone 7b winter hardy agave we could create. We had seven agaves flower that year, but only two had the epic proportions we required.

One of those was a selection of Agave x protamericana from a Yucca Do collection in Northern Mexico. By the time of flowering at 15 years of age, it had reached 5′ tall x 9′ wide.

Agave x protamericana and Agave americana are the two largest blue-foliaged agaves, but only Agave x protamericana is winter hardy for us, here in Zone 7b, since it also has some ancient genes from the hardier Agave asperrima, which adds slightly to its winter hardiness. You can distinguish the two plants by feeling the back of the leaves. Agave americana has smooth leaf backs, while Agave x protamericana has sandpapery leaf backs. The largest size listed for Agave americana in Howard Gentry’s Agaves of Continental North America, is 6′ tall x 12′ wide.

Agave x protamericana YD45-79

At the same time we had a blind flower shoot on our giant Agave x pseudoferox ‘Bellville’. Agave x pseudoferox is another ancient Mexican hybrid in need of a DNA workup. We think it’s probably a hybrid of Agave x protamericana with Agave salmiana var. ferox and possibly Agave gentryi). Commercially, it’s usually called Agave salmiana var. ferox, which is similar in appearance, but with absolutely no winter hardiness.

Prior to full flowering at 15 years of age, our giant specimen of Agave x pseudoferox ‘Bellville’ had reached a mature size of 4′ tall x 8′ wide. We were able to make the cross prior to it fully flowering, by using something we mentioned above that we call “blind shoots” or boners.

Being monocarpic plants, the rosettes of most agave species die after flowering, but side shoots are an interesting phenomenon we see on all of our Agave x pseudoferox cultivars and hybrids. These “blind shoots” emerge from underground stolons instead of from a rosette. They are much shorter than normal flowering shoots which emerge from the rosettes (2′ tall vs. 20′ tall), and they have no impact on the life expectancy of any of the rosettes.

In the case of Agave ‘Bellville’, our plant began producing blind shoots five years prior to the clump producing a full size, rosette-based flower stalk. The beauty of blind shoots is that they breed and pass along characteristics of the parent without the need for a tall ladder.

Agave 'Bellville' is another large blue green form that produced "blind shoots" which are flowering shoots produced from the underground stolons.
Agave x pseudoferox ‘Bellville’

We gave our hybrids the seed strain cultivar name, Agave ‘Bluebell Giants’. From these, we selected 23 clones, which were planted in the trial fields in 2016. Of those, only 4 survived our subsequent trials for winter hardiness.

Our seed crop of the hybrid from the two large growing blue green agaves.
Agave ‘Bluebell Giants’

Our best and most winter hardy seedling from the cross pictured below is now 6 years old in the garden. We’ve given this the name Agave ‘Supersize’. It has achieved a size of 6′ tall x 8′ wide in that time. To put this in perspective, it is larger at 6 years old than both parents were at 15 years old. If Agave ‘Supersize’ waits until age 15 to flower, it could easily reach more massive proportions that any Zone 7b winter hardy agave in existence.

Poli wants a Freda

A couple of years ago, we made bi-generic crosses of the North American Manfreda maculosa and the naturally occurring hybrid Mexican tuberose, Polianthes x bundrantii ‘Mexican Firecracker’. These fascinating plants were still in full flower prior to our first hard freeze in the last few days. These are images of our top three clones, which we refer to as x Polifreda. Because we used the non-fragrant tuberose species, there is no noticeable aroma, but we opted for a much more diverse flower color range instead.

Hopefully, next year, we can use these to cross with agaves to create a new series of xHanseras. Pollen has been gathered and stored in the refrigerator in case bloom times don’t coincide next year.

The Mysterious Howardara

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.

Randy Ferns

It’s not unusual for ferns to have sex in the wild, even with other species in the same genus. It is, however, unusual for them to have meaningful sex with ferns of an entirely different genus. Such an odd occurrence recently happened in the greenhouses of Louisiana’s James Georgusis.

One night, possibly after a wild Mardi Gras party, a willing Phlebodium got it on with a crested tongue fern of the genus Pyrrosia. The result was a new genus of fern, x Phlebosia. It was adopted and given the cultivar name, ‘Nicolas Diamond’. At least the parents had the good sense to sexually stay within the same family, Polypodiaceae

We planted our first specimens in the garden this February, and so far, it’s growing well. The key will be to see how much winter hardiness it has…fingers crossed. Both parents are pictured below the new hybrid.

Goodbye Champ!

We were saddened this past week to hear of the passing of our friend, Dr. Larry Mellichamp, age 73, after a three year battle with bile duct cancer. I first met Larry in the late 1970s, when he spoke to our Horticulture Club at NC State. Over the next 45 years, we interacted regularly, mostly during his visits to JLBG.

Knowing that Larry was in the battle of his life, we visited him at his wonderful Charlotte home garden last year (photo below). Even while he was ill, his wit remained razor sharp, and his humor as dry as the Sahara desert.

Not only did Larry teach for 38 years (1976-2014) at UNC-Charlotte, but he also managed the 10-acre UNC Charlotte Botanical Garden, which he turned into a must-see horticultural destination. Larry was a huge advocate of interesting plants, especially US natives. He was constantly dropping off new plants for us to propagate and share with a wider audience.

Larry was best known worldwide for his work with carnivorous plants, particularly with the genus Sarracenia. His “little bug” series, (Sarracenia ‘Lady Bug’, ‘June Bug’, ‘Love Bug’, and ‘Red Bug’, released in 2004, was the first widely marketed collection of pitcher plants, from his breeding work with the late Rob Gardener. In 2021, Larry was the recipient of the Lifetime Achievement Award from the International Carnivorous Plant Society…one of many such awards Larry received.

Larry was also a prolific writer. His books include: Practical Botany (1983), The Winter Garden with Peter Loewer (1997), Wildflowers of the Western Great Lakes Region with Wells/Case (1999), Bizarre Botanicals with Paula Gross (2010), Native Plants of the Southeast (2014), and The Southeast Native Plant Primer with Paula Gross (2020).

Larry and I connected on many levels, but we were both strong advocates for making rare native plants available for propagation and commercialization…something that is sadly the exception in the current world of botany. We hope others in the native plant community pick up the torch.

Larry is survived by his wife of 48 years, Audrey, his daughter, Suzanne, and a host of plants he spread throughout the world. Life well lived, my friend.

Hear, Hear…lend me an ear

We always look forward to elephant ear evaluation day at JLBG, which was recently completed.

The colocasia trial gardens at Juniper Level
Colocasia trials

Each year, Colocasia breeder, Dr. John Cho flies in from Hawaii to study and select from our field trials of his new hybrids. This year we were joined by Robert Bett, owner of the California-based plant marketing firm, PlantHaven, who handles the Royal Hawaiian elephant ear program. The JLBG trials consist of all named colocasia introductions growing alongside Dr. Cho’s new hybrids created the year prior.

After lunch, Jim Putnam from Proven Winners, joined us to see which remaining plants struck his fancy for potential introduction into their branded program. As you can see, lots of amazing plants didn’t make the final cut, which is necessary, since we’ll need more room for the new selections.

Plants selected for introduction are then sent to a tissue culture lab to be produced for the next step, which is grower/retailer trials. If these are successful, and the plant can be multiplied well in the lab, the plants are scheduled for retail introduction.

Hopefully, by now, most folks are familiar with our 2020 top selection, Colocasia ‘Waikiki’, which hit the market this year. There are more really exciting new selections in the pipeline, but we can’t share photos of those quite yet…stay tuned.

Mid-Summer Surprises

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.

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 sprengeri, whose foliage emerges in spring, is the only pink flowered species, almost always with a blue petal tip.

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 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 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.

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 caldwellii, named after the late Lycoris breeder, Sam Caldwell, is a hybrid between the spring-leafed species, Lycoris longituba and Lycoris chinensis.

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 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 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

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 ‘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'
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.

Crinum Time Again

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 'High on Peppermint'

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.

Yucc’ing it up

We’ve been playing around with yucca breeding for almost a decade, and now have hybrids that include from 3-5 different species. Here’s a shot of one of our evaluation beds when it was in full flower recently. Flower spike height ranged from 3′ to 10′. There should be some wild and crazy introductions once our trials are finished.

Afternoon Delights

Plant breeders are an odd sort…people who are never satisfied with their results, and as such are always looking to improve even the most fabulous creation. We’ve been dabbling with crinum lilies for several years, and the first photo below is one of our newest creations, Crinum ‘Razzleberry’, which is rather amazing. Despite this success, we return to the breeding fields to see what else awaits from additional gene mixing.

Crinum flowers typically open in early evening…5-7pm for us. The first step in breeding is to remove the petals, to have good access to the male pollen (the powdery tips atop the six pink thingys), and the female pistil, the single longer thingy with a dark pink knob at the top and a bigger knob at the bottom. Most crinum pollen is yellow, but depending on the parentage, some hybrids have white pollen.

The male thingy is known as a stamen, comprised two parts, the filament (the pink thing), and the anther (the part with the pollen). The female parts are known as the pistil, comprised of the ovary (bottom), the style (the pink thingy), and the stigma (the sticky knob at the tip.

In breeding, the anther is removed and the pollen is dusted on the stigma of a different plant to make the cross. Crinums produce an insane amount of nectar, so crinum breeders are constantly dodging sphinx moth pollinators, as well as dealing with the ant superhighway below as they haul off the nectar.

If your cross is successful, you will have seed forming in about a month. The seed are quite large, and must be planted immediately, since they have zero shelf life.

Crinum seed pods

Once the seeds germinate it normally takes 4-5 years for your new seedlings to bloom. During the first several years you can evaluate vigor and growth habit, but the final evaluation can’t be made until it blooms.

Raisin’ Cain

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.

Canary Treasure

This is our first flowering of Dracunculus canariensis, the rare cousin of the more commonly-grown aroid Dracunculus vulgaris. Dracunculus canariensis hails from Madeira (reportedly extinct) and the nearby Canary Islands, all off the coast of Morocco.

We inherited our specimen from the late plantsman, Alan Galloway, who planned to cross it with Dracunculus vulgaris. The task now falls to us. Both species have a similiar chromosome count of 2N=28, so this should be a easy cross by saving pollen. To us, the flower smells like watermelon rhine, which is a nice change from the more offensive smell of its sibling.

Redneck Lupines on Parade

Our baptisia introductions are looking absolutely fabulous this week. Here are a few in case you missed the first weekend of our open house. Baptisia ‘Aspriing’ (top) with its long spikes of lavender blue flowers, followed by the incredibly dense flowering Baptisia ‘Blonde Bombshell’. Next is our Baptisia ‘Cherry Pie’, which brings a new color to the genus, and ending with Baptisia minor ‘Blue Bonnet’ with it’s enormous blue flowers. Baptisia are a North American genus of long-lived perennials that can grow equally as well with cactus or as a marginal aquatic…as long as they have full sun.
