Spiny is as Spinosus Does

In 60 years of gardening, I’ve yet to seen a nursery that offers Acanthus spinosus, who actually has the correct plant. 100% of everything in the commercial trade is actually a hybrid of Acanthus hungaricus and A. spinosus, which looks nothing like the true species.

Even authoritative on-line reference sites which should know better, all show the wrong plant, identified as Acanthus spinosus. To make matters more confusing, there is also a hybrid of Acanthus mollis x spinosus in the trade, known by the name Acanthus x spinosissimus. The more prevalent hybrid I mentioned earlier has yet to get a published notospecific name. Perhaps the name Acanthus x spinaricus would make sense.

Below is our plant of the true Acanthus spinosus this month, grown from seed wild collected in Greece, where it grows natively. Perhaps one day, we’ll have enough to share. Since no one has grown the correct plant, the reported hardiness data you find on-line and in reference books is worthless. We’d guess Zone 7a-9b, at least.

Who Called a Cop-tis?

We love the miniature Coptis japonica var. dissecta in full seed now. This dwarf, evergreen, woodland-growing member of the Ranunculus family (Clematis, Helleborus), has small white flowers in the winter, but we adore the seriously cute seeds heads that are adorned in March and April. Not only is this Japanese endemic a cool garden plant, but it’s highly prized as a medicinal plant, thanks to chemicals harvested from its roots, which are used to treat an array of ailments, from infections to pain, dysentery, fevers, and much more. Hardiness Zone 5a-8b.

False Red Agave

Looking great in the garden now is the false red agave, Beschorneria. Beschorneria is a small, little-known genus of only 8 species of plants in the Asparagaceae family–first cousin to the better known genus, Agave. Beschornerias are native from Northern Mexico, south to Honduras. Through the years, we’ve grown 7 of the 8 species, having not bothered to try B. wrightii, due to it’s tropical origin.

The only species that has proven reliable and evergreen here is Beschorneria septentrionalis–a species introduced by the former Yucca Do Nursery from their collections in Northern Mexico.

Several years ago, we were given seed of hybrids of B. septentrionalis x B. yuccoides ssp. dekosteriana. Most of the hybrid plants died because they inherited too many genes from the more tender B. yuccoides, but two plants still remain. Below is one we named Beschorneria ‘Fire Towers’, which appears close to B. septentrionalis in appearance, but perhaps with a bit more vigor.

Korean Celery

I first grew Korean celery for years for the flowers, never realizing it was an edible food crop…a first class edimental! I have a fascination for plants in the Apiaceae family, whose members include Angelica, Queen Anne’s Lace (Daucus), carrots (Daucus), celery (Apium), parsley (Petroselenium), etc. Not only are many of the family members attractive in flower, but they are supremely attractive to pollinators, especially wasps.

Not all of my Apiaceae experiments have turned out well. More often than not, members of the family are short-lived (monocarpic or biennial), while other are prolific seeders. One which has far exceeded my expectations is the Korean native, Dystaenia takesimana.

Dystaenia takesimana is an endangered native to Ulleung Island, where it’s known by the local name, Soembadi. Most likely, dystaenia is endangered because it was also used to feed livestock (pigs). Humans eat Korean celery mostly in late winter, when it can be eaten raw like celery, or boiled, tasting quite like spinach.

This amazing evergreen perennial puts on a show with 5′ tall stalks of white umbels, starting for us in early June. When flowering is complete, the stalks die back as the new basal foliage emerges. Unlike many members of the family, the attractive cutleaf basal foliage remains evergreen all winter. You’ll see this popping up soon in an upcoming Plant Delights catalog. We hope you enjoy this as much as we have.
