Dalea formosa Torr.
Feather dalea, Featherplume
Synonym(s): Parosela formosa
USDA Symbol: dafo
USDA Native Status: L48 (N)
Featherplume is a 2-3 ft., thornless, colony-forming shrub which can reach 6 ft. in height. A low scraggly shrub bearing tiny, pinnately compound leaves and pea flowers with yellow and bright purple to pink-purple petals in short, head-like racemes. It forms large, low-spreading, finely-textured mounds with silvery, delicately compound leaves. Short, spike-like clusters of fuzzy, purple flowers cover the blooming plant. Close inspection reveal a bright yellow banner petal contrasting with the rose-purple corolla. Blossoms are followed by flat, shaggy-haired seed pods.
One of many shrubby species of Dalea, this plant--with its dark bark, contorted branches, and small leaves--is an excellent candidate for bonsai.
