It has wonderful evergreen foliage with brilliant blooms from late spring through late summer. Long-lived, this perennial is so adaptable that it also thrives in humid climates.
CareProvide full sun and poor, gritty, sharply drained soil.
PropagationThe seeds of wild buckwheat are oblong and nutlike. Sow them in winter, and with some freezing and thawing, expect a thick crop of seedlings come April and May, which will produce husky plants by summer's end.
ProblemsPowdery mildew, rust, spider mites, aphids.
