Western redbud
Cercis occidentalis
A western North American native large shrub or small multi-stemmed tree that erupts in clouds of magenta-pink pea-family flowers along bare branches in early spring - often before the leaves expand. The round, heart-shaped blue-green leaves with palmate venation follow, and flat 2-4 inch seed pods ripen burgundy-red and persist into winter. A drought-tolerant, butterfly- and bee-supporting native of dry slopes from northern California east to southern Utah and south to Arizona.
