Redwing is grown less for the flowers than for what follows them. Through the warm months this fast, twining, semi-woody climber carries loose clusters of small clear-yellow flowers along the stems, pretty enough in passing, but the real event comes after, when each pollinated bloom ripens into a bright red winged fruit, a samara built exactly like the spinning key of a maple. In quantity the red keys smother the vine and glow against the small, neat foliage, an unexpected and long-lasting display that few visitors can name.
Hypericum prolificum lives up to the name, prolific, disappearing each summer under a heavy crop of bright yellow flowers, each three-quarters of an inch to an inch across and stuffed with a golden brush of stamens. The shrub is dense and rounded, with arching branches, narrow shiny leaves, and reddish, exfoliating bark that peels to show paler layers once the foliage thins.
Rhododendron atlanticum, the coastal or dwarf azalea, is a low, colony-forming native of the open pine woods and sandy flatwoods of the mid-Atlantic and Carolina coastal plain. Unlike the tall wild azaleas of the mountains, this species stays close to the ground, often no higher than the knee, and spreads by underground runners, or stolons, into broad, drifting colonies. The bluish, glaucous foliage is a hallmark, cool and sea-gray, and the species name atlanticum simply marks the plant's home along the Atlantic seaboard. The genus name Rhododendron means rose tree in Greek; azalea comes from azaleos, meaning dry, a fitting root for a shrub of sandy, well-drained ground.
The white form of the latest-blooming native. Wisteria macrostachya 'Clara Mack' is a twining, deciduous Kentucky wisteria with compound leaves and long, hanging clusters of pure white flowers, a splendid white version of a species normally blue. The racemes run longer and open later than those of the other native, Wisteria frutescens, extending the native wisteria season.
