This summer-deciduous small tree has an extensive range, from west Texas to California and into Mexico. Older trees develop gnarly, twisted trunks. The compound leaves have slightly toothed, sandpapery leaflets. Flattened clusters of creamy-white flowers occur in the winter and spring. The edible, tart, blue-black fruit is a favorite of many migratory birds. Plant in full to part sun and provide moderate summer irrigation to speed the growth rate.
