Endangered Species

Rare plants kept in cultivation, one garden at a time. Every plant in this collection is nursery-propagated, never wild-collected, and many are species of genuine conservation concern: Southeastern endemics with shrinking wild ranges, and old-world rarities held now by only a handful of growers. To plant one is a small, quiet act of keeping a species in the world.

Spiraea virginiana
Virginia Spirea
Spiraea virginianaVirginia Spirea

Important: This plant is sold within South Carolina only.In the high-gradient streams of the southern Appalachians, the Gauley, the Bluestone, the Greenbrier, scattered tributaries of the New River, and a handful of similar second- and third-order rivers, grows a shrub that holds on to rocky bars and scoured banks where almost nothing else can. This is Spiraea virginiana, the Appalachian spiraea, a plant that evolved alongside the violent flood regime of these mountain rivers and depends on that disturbance. The floods scour competing vegetation off the banks, expose mineral soil for germination, and break off rhizome fragments that float downstream to colonize new sites. Where the rivers were dammed, the floods stopped, and the spiraea began to disappear.

Clematis morefieldii, Morefield's leather flower, downy pink nodding urn-shaped flower on a hairy vine.
Morefield's Leather Flower
Clematis morefieldiiMorefield's Leather Flower

Clematis morefieldii, Morefield's leather flower, is one of the rarest of the native clematis, a delicate climbing vine known in the wild from only a small pocket of limestone country around Huntsville, Alabama, and just into Tennessee. Like the other leather flowers, this species trades broad, flat blooms for small, nodding, urn-shaped flowers, here a soft, downy pink, their sepal tips curling back at the rim. The stems and leaves carry a fine coat of whitish hairs, giving the whole plant a soft, silvered look.

Rhododendron chapmanii
Chapman's Rhododendron
Rhododendron chapmaniiChapman's Rhododendron

Chapman's rhododendron is a compact evergreen shrub of six to eight feet, carrying small, thick, distinctly rounded leaves in a light green, with margins that roll under slightly at the edge. In late spring the plant opens clusters of rose-pink flowers, funnel-shaped and freely borne, and the effect on a well-grown specimen is generous rather than sparse. Set beside the closely related Rhododendron minus, this plant reads lighter and rounder in the leaf, and most authorities now treat the two as one species, filing this one as Rhododendron minus var. chapmanii. We keep the name under which gardeners and native-plant people know the plant.
