Sulfur flower (Eriogonum umbellatum)
ee-ree-OG-oh-num um-bell-AY-tum

Wild buckwheats have assumed star roles in drought-tolerant landscapes throughout the West, and none is more useful than sulfur flower. 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.

Care: 

Provide full sun and poor, gritty, sharply drained soil.

Propagation: 

The 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.

Problems: 

Powdery mildew, rust, spider mites, aphids.
