Agave ‘Prince of Whales’

Our 2016 century plant hybrid is looking quite lovely in the garden this month. This plant, which we named Agave x victorifolia ‘Prince of Whales’, is a hybrid of the Whale’s tongue century plant, Agave ovatifolia (male parent), and the Queen Victoria century plant, Agave victoriae-reginae (female parent). Since both parents are non-offsetting, this means

Pir a whattia?

You go straight through to the round of botanical superstars if you recognize this little-known southeast native (SC to Florida), Piriqueta caroliniana. This Patrick McMillan collection from coastal SC has thrived all summer in our full sun rock garden, flowering constantly, with new flowers opening every other day. This oddity is a member of the

Stunning bergia

Looking lovely in the garden today is the fall-flowering geophyte, Sternbergia sicula. This Mediterranean native is found in the wild growing on alkaline hilly sites. Some taxonomists list it as a subspecies of the more common Sternbergia lutea, but it seems consistently smaller. At JLBG, our plant thrives in the crevice garden. Hardiness is Zone

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
