This airy, semi-evergreen shrub or small tree is native to west Texas and Mexico. The bi-lobed, gray-green leaves are shaped like little butterflies. Small, delicate white five-petaled flowers are produced from late spring to early summer. It is tolerant of sun and drought, but also handles part shade and ample moisture. While it tolerates most soils, it requires good drainage. The growth rate will be slow to moderate growth depending upon available moisture. This species tends to be brittle, and should be protected from strong winds.
