Senna wislizenii (Cassia wislizenii)

Fabaceae (Leguminosae)

Canyon senna is native to dry, rocky soils to 5000 feet in West Texas, New Mexico, Arizona and Mexico. As our only true native shrub senna, it has pinnately compound leaves and crowded panicles of large, showy bright yellow flowers which contrast nicely with its small leaflets and dark branches. This very ornamental and tough Chihuahan native is late to leaf out in the spring. Canyon senna has numerous spreading thorny branches which will require some pruning to shape its somewhat rangy habit.
