This subtropical small tree is native in Texas but only in the mild climate area of the lower Rio Grande Valley. It is grown in other areas but is typically killed to the ground in winter in all but very mild areas. Outside the essentially frost free areas it is treated almost like a perennial that reaches 5 to 6 feet. Its ferny foliage, racemes of golden yellow fragrant flowers, and its high tolerance to heat make it a favorite ornamental well outside its native range. Plant in sunny well-drained site and provide winter mulch in areas where freezing temperatures occur. These plants were grown from seed collected at the outstanding campus botanical garden at Armstrong Atlantic State University in Savannah, Georgia.
