Cat Whiskers Cactus

Our planting of Glandulicactus wrightii is looking quite lovely as we head into fall. Sadly, few folks take time to closely examine the fascinating and intricate arrangements of cactus spines. Glandulicactus wrightii, which is native to Texas and adjacent Mexico has amazingly long, hooked spines that resemble cat whiskers. Long term winter hardiness is hopeful

Access to Albanian Acis

Just finished flowering in our crevice garden is the amazing member of the Amaryllis family, Acis ionicum. This little-known Albanian snowbell hails from small areas of Coastal Albania and Western Greece, as well as a few of the adjacent islands. The flowers of this species are quite huge, compared to the better known A. autumnalis.

Purr-fect Pussy Toes

We love the miniature silver mats of Antennaria parviflora (little-leaf pussytoes). This little-known North American native (Canada south to Arizona) forms a tiny, 1″ tall groundcover that’s hard to the touch. In spring, the patch is topped with short fuzzy spikes of brush-like white flowers. The plant below, which measures 1′ in width, is only

Little Big Man

Most highly prized rock garden plants originated somewhere other than the Southeast US. One notable exception is Bigelowia nuttallii, or if you prefer common names, Nuttall’s rayless goldenrod. This fascinating plant resembles a whisk broom that just swept up a spilled bottle of mustard. Named after English botanist/zoologist Thomas Nuttall (1786-1859), who lived in the

Stingray in the Garden

We love the spineless Agave bracteosa ‘Stingray’ in the garden. We’ve had these dotted throughout the garden since 2017, and so far, with good drainage, they’ve handled our winters quite well, which is certainly not normal for a variegated century plant. This particular species prefers part sun to light shade. Hardiness is Zone 7b/8a and

A Golden Native

Here’s a photo this week of one of our favorite North American native plants, Juniperus horizontalis ‘Copper Harbor’. This would certainly add significant year round color interest to any native plant garden. In our trials, this is far and away the best of the golden Juniperus horizontalis cultivars. We offered this selection for a couple

Thyme Flies, Thymophylla Flowers

We are in love with the long-flowering Thymnophylla pentachaeta var. pentachaeta ‘Laredo Gold’, which graces us with masses of gold flowers from spring through fall, in our sunny, dry rock garden. This Patrick McMillan collection comes from a population in Texas. Not only is this short-lived, southwestern US native reseeding perennial great in flower, but

Baccharis-foliaged Beardtongue

We are enjoying the rare Penstemon baccharifolius this summer in our high/dry crevice garden. This species is native to limestone ledges up to 6,500′ elevation from the Edwards plateau in Texas south into Northern Mexico. This species hates our summer rains, and we had given up on growing this until we built our alkaline crevice

They Came, They Listened, They Learned, They shared

We’ve just wrapped up the 2022 Southeastern Plant Symposium in Raleigh, and were thrilled to have nearly 200 attendees. It was great to be back in person after two years of remote Zooming. The symposium is co-sponsored by the JC Raulston Arboretum and Juniper Level Botanic Garden, with all proceeds split between the two institutions
