Mesquite, Chilean Mane or Golden Mane
Prosopis chilensis var. thornless

Don't shudder at the thought of planting this Mesquite -- It's thornless. The lacy leaves are golden chartreuse and the seeds are sterile. It is so beautiful, it is hard to believe that it has the hardiness of the native species, can thrive in central Texas heat, and is accustomed to the cold spells since it is endemic to the desert plains of Chile. It is a relatively fast growing tree, but seldom reaches more height than 20' so it should be planted as a large shrub or small tree for full sun in well-drained soil. It's drought-tolerant and an ideal addition to a xeric garden. This tree thrives in USDA zones 8 through 11.
