Shrubby senna (S. wislizenii) is a native of southern Arizona, ranging from the low deserts in Mexico to 3,000- to 5,000-foot elevations on gravelly slopes.

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. Shrubby senna has numerous spreading thorny branches which will require some pruning to shape its somewhat rangy habit.

It is labeled as either Senna wislizenii or Cassia wislizenii in the nurseries.
