A broad semi-evergreen tree to 20 to 25 feet tall that has reddish-brown bark with low branches. In early to mid-summer appear the terminal clusters of 2 to 3 inch wide deep yellow flowers, with scattered blooming later. The flowers are followed by 1 to 2 foot long bean-like pods. Plant in full sun in a fairly well-drained soil and give occasional to little irrigation. Hardy to about 25 degrees F and tolerant to short duration freezes a bit lower.
