Ungnadia speciosa

Mexican Buckeye
Deciduous, Shrubs, Trees

Useful small tree for desert areas. Native to western Texas, southern New Mexico, and northeastern Mexico. Grows to 15–20 ft. tall and wide with large, dark green, divided leaves that turn yellow in fall. Showy, rose-pink flowers on bare branches in spring attract butterflies; the blooms are followed by unusual, three-part seedpods containing three hard seeds. Pods hang on bare branches in winter. Naturally multitrunked but can be trained to a single trunk tree. Grows best in well-drained, alkaline soil.
