Long-leaf Buckwheet

We admit to a long-standing case of buckwheat envy. Every visit to the worlds great rock gardens, such as the Denver Botanic Garden, leave us lusting to grow the rock garden genus, eriogonum. We’ve killed many members of the genus, since they truly hate our humid and wet summers. Even our crevice garden was no help in keeping these alive, even including our reportedly easy-to-grow Appalachian native, Eriogonum allenii. After almost giving up several times, we can finally declare success with the Texas native Eriogonum longifolium, from our East Texas botanizing expedition. Here’s our clump in full flower, and quite happy in one of the rock garden sections. Granted, it’s not as stunning as some of the species that thrive in Denver, but hey, we can now check that genus off the list.

Eryngium longifolium

Meet Anne Bishop

Early fall is peak ginger lily season, and Hedychium ‘Anne Bishop’ is looking particularly stunning this week. This amazing cultivar always ranks near the very top of our favorites list.

Reveling in Ravenel’s Rattlesnake Master

Late summer/early fall is show season for Eryngium aquaticum var. ravenelii…a superb southeast native plant that’s almost unknown by native plant enthusiasts. In the wild, it grows in seasonally flooded ditches, but in the garden at JLBG, our plants thrive in typical garden soil with an average amount of moisture. Here are our plants flowering now…each filled with an array of pollinators.

Beetles Reunion

We were harvesting our abundant fig crop last week, and were astounded by the number of green June Beetles also enjoying the ripe figs. This indulging makes the beetles into a sweet and tasty snack for the likes of crows, grackles, blue jays, and mockingbirds.

After gorging themselves through the summer, the beetles burrow 6-8″ down into the soil where they lay their eggs, which hatch in a couple of weeks and then overwinter as grubs, which feed on compost during the winter months. While living as larvae, the grubs are food for many underground mammals as well as above ground foragers like possums, racoons, and skunks.

Although green June Beetles are voracious feeders of over ripe fruit, that probably isn’t fruit you were going to eat any way, so they really aren’t damaging to the garden. Green June Beetles are much larger and less impactful than the dreaded Japanese beetles.

We actually enjoy these fascinating insects and don’t find any need to try and eradicate them. Since they don’t bite or sting, they are great for kids and adults looking for unusual sensory experiences to handle. Holding a green June Beetle in your hand is the best way to get a real buzz, and still be able to drive safely afterwards. The only downside is that they may poop on your hand, but that also is a new experience for most folks.

The Surprises Continue

The parade of Lycoris (surprise lilies) continue into their third consecutive month as we move through September. The key for a succession of flowers is having a large number of cultivars. So far at JLBG, we have flowered 300 different cultivars this summer. Here are a few recent ones. The varieties which form fall foliage are winter hardy in Zone 7a/b and south. Those whose foliage emerges in late winter/early spring are winter hardy in Zones 4/5.

Lycoris x rosea ‘Berry Awesome’
Lycoris x rosea ‘Caldwell’s Red’
Lycoris x rosea ‘Kariwatashi’
Lycoris x rosensis ‘Colorama’
Lycoris x rosensis ‘Three Towers Mirroring the Moon’
Lycoris x sprengensis ‘Lemon Cheesecake’
Lycoris x straminea ‘August Lemon’
Lycoris x straminea ‘Caldwell’s Original’
Lycoris x straminea ‘Red Hot Lover’
Lycoris x straminea ‘Ring of Gold’

The Case of The Beautiful Imposter

This is one of the rare summers we actually got flowers on Amaryllis belladonna in the gardens at JLBG. The only problem is that they aren’t really Amaryllis belladonna. This poor South African native has suffered a series of nomenclatural mix ups over the last 250 years, that sadly continues today.

First was the battle over which plant really belongs to the genus name, amaryllis. The mix-up started with the grandfather of modern taxonomy, Carl Linnaeus, when he published the genus name Amaryllis in 1753. In his initial publication, Linnaeus applied the name amaryllis to a group of plants, which later turned out to include at least five different genera; amaryllis, nerine, zephyranthes, sprekelia, and sternbergia. A few years later in 1819, botanist William Herbert and others tried to clean up the mess using Linnaeus’s notes, and in doing so, assigned the genus name amaryllis to the solitary South African species, Amaryllis belladonna, which had been in Western cultivation since 1633.

Fast forward 119 years to 1938, when taxonomist Cornelius Uphof upset the proverbial apple cart when he published a paper in which he declared that the assignment of the name amaryllis for the South Aftrican plant was against Linnaeus’s wishes, since it was clear to Uphof that Linnaeus intended the genus Amaryllis to be applied to the American genus, Hippeastrum. Uphof’s paper renamed the American genus Hippeastrum to Amaryllis and the South African Amaryllis belladonna became Callicore rosea. This caused quite a taxonomic uproar which would continue for another 50 years.

The following year, 1939, taxonomist Joseph Sealy dug deeper into the original amaryllis name mix-up, and found it impossible to determine which plant Linnaeus intended to bestow with the genus name, Amaryllis, since most of Linnaeus’s original description referenced the South African plant, and only one small part referenced the American plant. Consequently, Sealy left the name amaryllis to apply to the solitary Amaryllis belladonna, and not to the much larger genus Hippeastrum.

The battle was far from over, and in fact, it turned into a war, led by American taxonomist Dr. Hamilton Traub, who from 1949 until his death in 1983, was defiant that the genus name amaryllis should instead apply to the American hippeastrums. Finally, in 1987, after Traub’s death, the International Botanical Congress confirmed the assignment of the name amaryllis to the South African species. Despite this resolution to 250 years of wrangling, most gardeners still refer to the plants that they grow widely in homes and gardens for their large flowers as amaryllis and not the proper name, hippeastrum.

One would hope that the 1987 decision would be the end of the mess, but not so fast…there was yet another taxonomic snafu. Amaryllis belladonna is a plant which is widely grown throughout California, where it thrives and flowers annually. But, is it really Amaryllis belladonna? While it’s certainly not a hippeastrum, the answer is no. To solve this mix-up, let’s step back a few years, to 1841, when Australian plantsman John Bidwill, first crossed Amaryllis belladonna with another African relative, brunsvigia, creating a bi-generic hybrid that would become known as x Amargyia parkeri. Because x Amargyia parkeri had more flowers, a more radial flower head, and better vigor, it gradually replaced true Amaryllis belladonna in cultivation, especially in California. I chatted with Californian Bill Welch (Bill the Bulb Baron), the largest grower/breeder of Amaryllis belladonna, prior to his untimely death in 2019. Bill admitted that everything he grew and sold as Amaryllis belladonna was actually the hybrid x Amargyia parkeri. Nurserymen have a bad habit of using incorrect names, because they realize that names which are familiar to customers always sell better.

If that’s not confusing enough, we should add that about half of the people who grow Lycoris x squamigera, a Zone 4 hardy bulb, also have their plants also labeled as Amaryllis belladonna, which is only winter hardy from Zone 8 south. We can thank several large mail order bulb catalogs who have no interest in either correct nomenclature or correct photography for that fiasco.

To quote the late Paul Harvey, “And now you know the rest of the story.”

So, do you see why plant taxonomist generally have little hair remaining?

Mexican combo

Just caught this image of two North American (Northern Mexico) natives snuggled up closely together in the garden. At top is one of the spider lilies, Hymenocallis acutifolia, and wrapped around its ankles is Tradescantia pallida. We truly love Tradescantia pallida as a great combination-enhancing perennial that’s completely winter hardy here in Zone 7b.

Old Fashioned, but not out of Fashion

Hemerocallis ‘Autumn Daffodil’ was introduced in 1949, but remains one of the most incredible daylilies we grow here at JLBG. The 3′ tall, branched, sturdy, upright stems are topped with an abundance of amazing highly fragrant yellow flowers starting in July.

Blues Brother Bookends

Most garden visitors have never met our two indoor cats, but we couldn’t resist sharing this recent photo of Jake and Elwood posing as bookends. The Spinx statues ain’t got nothin on these guys. Both arrived a few years ago as adoptees after being found abandoned and thrown in a nearby river.

Cooking up a Joe-Pye

We wanted to create a buffet for local butterflies by our patio, and a mass planting of Eupatorium purpureum ‘Little Red’ did just the trick. Not bad for a highway ditch native.
