Opening up a Mis-can-thus of worms

Flowering this week at JLBG is the amazing Miscanthus transmorrisonensis. Many gardeners, who blindly believe everything they read/hear think the genus miscanthus is the horticultural version of the devil itself. Like everything in life, it’s all about those pesky details, which so many people simply don’t want to be bothered with. Most miscanthus in the

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

Spathicarpa…a true BIO plant

Plant nerds use the term BIO plant, short for Botanical Interest Only, for plants which have little, if any ornamental value, but are highly prized by crazed plant collectors. Spathicarpa hastifolia is such a plant. This odd aroid from Southern Brazil has actually thrived in our woodland garden since 2019. The coldest winter temperatures we’ve

Pteris on the Terrace

We’ve long loved the fern genus, Pteris (pronounced terrace), but struggled for years to find any that were winter hardy here in Zone 7b. That changed with our 1996 Chinese expedition to Yunnan Province, and later a subsequent expedition by gardening friends to Sichuan Province. On both trips, high elevation collections of Pteris vittata were

Reticulation anyone?

We ran across this fascinating reticulated leaf form of the US native (every state east of the Mississippi) groundcover partridge berry (Mitchella repens) last week, when tromping through the woods near JLBG. We’ve taken a few cuttings that will be evaluated here for garden performance. In 60 years of botanizing, this is the first form

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

Christmas in June

While doing some local botanizing recently, we ran across this fascinating form of our native Christmas fern, Polystichum acrostichoides. Not only was it more compact than any others in the area, with more “orderly” fronds, but it also showed none of the typical terminal spore production that would be expected this time of year. Since
