Flaming Buckeye

We saw this amazingly colored buckeye (Aesculus pavia) on a recent visit to the NC Arboretum in Asheville. I’ve seen countless individuals of this species, both in the wild and in gardens and have never seen a color like this. We have encouraged them to get this grafted and introduced.

Ammocharis…the neglected amaryllid

Since we don’t have an open house in June, I wanted to share photos of Ammocharis corranica in flower now. This easy-to-grow amaryllid has thrived in the gardens at JLBG since 2004. First cousin to the better known genera like amaryllis, crinum, and lycoris, the South African ammocharis makes a very short, but incredibly showy bulb for a sunny garden spot.

The ultimate BIO plant

In the plant world, plants that have no chance of selling, except to a tiny few crazed plant collectors, are called BIO plants, which stands for “of botanical interest only”. Coptis japonica var. dissecta fits the bill on all accounts. This fascinating Asian woodland perennial maintains a small evergreen rosette, topped in spring with tiny spikes of tiny fuzzy white flowers that age to these fascinating seed heads in the garden now.

A Rainbow of crazy cactus colors

Here are a couple more cactus hybrids flowering in the gardens of JLBG, both created by our volunteer cactus/succulent curator, Vince Schneider. The first is a Trichocereus cross, the parents of which were created by a former volunteer, Mike Papay. Vince crossed two of Mike’s selections to come up with the gem. My camera had trouble since I don’t think this color is supposed to exist in nature.

The second is Vince’s cross of Echinocereus dasycanthus x ctenoides…an amazing blend of colors. We can’t imagine anyone with a dry sun garden that isn’t growing these amazing plants.

Hungry for a Blueberry Muffin?

The non-weedy Ajuga ‘Blueberry Muffin’ from the breeders at Terra Nova has really put on quite a show at JLBG this spring. We love the non-seeding and slow spreading traits…not to mention the amazing floral show.

Spring fireworks

Magnolia officinalis var. biloba ‘Fireworks’ is stunning in the garden, from its dark purple buds to the vivid pink flowers. Typical Magnolia officinalis var. biloba has white flowers, so this amazing plant is most unusual.

Uun-yaaw \noun\ (Cajun)

We’ve got some really superb unyaaw’s blooming now. Actually, if you’re not of the Cajun persuasion, they’re onions…of the genus Allium. The North American native Allium canadense is quite showy in the late spring/early summer garden. The first is a superbly dense flowering selection, Allium ‘White Flag’, made by the late bulb guru, Thad Howard. Allium canadense var. lavendularae is a lovely purple-flowered form. Purple seedlings pop up occasionally in wild populations, but we’ve been able to isolate a particularly nice purple form from light lavender flowering plants that originated in Kansas, shared by plantsman Aaron Floden.

Titilating Bletilla

Our oldest clumps of the hardy orchid, Bletilla striata are just amazing…once we learned that these aren’t shade plants. These are under a tall pine and get 1-2 hours of sun.

Orangeola

Sounding more like a soft drink/crayon combination, Orangeola is actually a stunning selection of weeping, dissected, purple-leaf Japanese maple. Our oldest specimen at JLBG is now 27 years old, and measures 5′ tall x 12′ wide…sorry that size doesn’t really match what you’ll find on-line. We think it’s one of the most handsome clones we grow.

Obscure and Ambiguous

To identify plants that are new to us, we start with the time-tested step of determining how close plants look to relatives we already know. This comes first, before we dive into floral dissection, etc. In most cases, we can get pretty close to a correct id, since we’ve grown and seen such a large number of plants. Two plants that threw us completely off the trail when we first saw them, are flowering now in the crevice garden here at JLBG.

The first, below, is Digitalis obscura, the Spanish Foxglove. I’d have lost big had I wagered on its identity when I first saw this, since I would have bet the farm that it was a penstemon, since the flowers and foliage share such an amazing resemblance to that genus. It’s taken us years to find a spot well-drained enough for this to survive in our rainy, humid, climate, but the wait was worth it.

Digitalis obscura

The second plant that doesn’t seem to fit its genus is also flowering now in the crevice garden…Penstemon ambiguous. This Southwest/Great Basin native, known as sand beardtongue, looks nothing like other members of the penstemon family, which are usually easily recognizable at first glance. Instead, it could easily be mistaken for a phlox. This is our third year for this gem, so perhaps this may appear in our nursery offerings one day.
