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.

Memorial donations may be sent to the Foundation of the Carolinas for the “Mellichamp
Garden Staff Enrichment Fund”, 220 North Tryon Street, Charlotte, NC 28202. For bank transfer instructions contact donorrelations@fftc.org or 704-973-4529. All are invited to share memories and photos of Larry at https://link.inmemori.com/mDPxXH . A public memorial service will be planned for October at the UNC Charlotte Botanical Gardens. Look for an announcement on their website.

Hear, Hear…lend me an ear

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

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.

JLBG staff members, Jeremy Schmidt and Zac Hill spent most of the morning working with Robert and John on the time-consuming evaluation process.

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.

John Cho, Robert Bett, Jim Putnam

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.

Lycoris field trials @ JLBG
Lycoris 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 longituba ‘Early Riser’
Lycoris longituba ‘Trumpeteer’

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 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 ‘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.

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 ‘Superliscious’

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 ‘Razzleberry’

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.

Crinum stamen and pistil

Crinum stamen and pistil

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.

Nectar ant interstate highway

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.
