Beyond Flowers

We love the appearance of plants like agapanthus in the fall, long past the season when the showy blue flowers graced the top of each now browning stalk. In fall, it’s more like looking out on a mass of punk rock hairdos. These garden features are so much more interesting than flat beds of mulch, created far too early by garden neat freaks. This is the cultivar Agapanthus ‘Prolific Blue’ which puts on a superb fall/winter show.

Jammin’ Jame

Salvia regla ‘Jame’ (pronounced Haam-hey) is looking so wonderful this time of year. This amazing North American native (US/Mexico) was originally shared back in 2000, by the late Salvia guru, Rich Dufresne. It has adorned our gardens every year since with these amazing fall shows. Hardiness is Zone 7b and warmer.

Happened on a Habenaria

Looking particularly good this week is one of the Southeast US (NC to Texas) native water orchids, Habenaria repens. This gem flowers through most of the growing season, and hasn’t slowed down as we enter November. Water spider orchid can grow both as a marginal or as a true aquatic. Our plant is growing in one of our crevice garden seeps. We’re working to get this really cool native propagated and available in the future.

Digging Cotton

Looking lovely in the garden is week is Gossypium thurberi ‘Mt. Lemmon’…our introduction of one of the progenitors of modern day cotton. On a 2005 botanical expedition, we discovered this North American native perennial hibiscus relative, known as Desert Cotton, growing in the mountains of Arizona. In the garden, it’s a superb flowering machine for late summer and early fall. Winter hardiness is probably Zone 8a and warmer.

Sleeping Beauty

We’ve written before about plants that get much larger than we are told in the catalog descriptions. Well, our latest example is Buddleia ‘Sleeping Beauty’, a hybrid of Buddleia lindleyana and Buddleia davidii. In two short years in the garden, it became a monster, reaching a 7′ tall x 12′ wide with no sign of slowing down. It was quite lovely and floriferous, but has now become a welcome member of our compost pile…sigh

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’

Late Summer Rains

We are fascinated with the wonderful genus zephyranthes (rain lilies). Zephyranthes are unobtrusive, summer-flowering bulbs that can fit in any garden, with a flower color ranging from yellow to white to pink. The great thing about zephyranthes is the lack of large foliage that often accompanies many other spring-flowering bulbs, so site them in the front of the border, or in a rock garden to be best appreciated.

Zephyranthes are one of our specialty collections at Juniper Level Botanic Garden, with 25 species and 257 unique clones. Here are a few of the zephyranthes blooming this morning in our alpine berm. You can view our entire zephyranthes photo gallery here.

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.
