Huge tropical leaves (6-12 in.) provide good shade and a backdrop for white flower clusters in July. Has long bean-like fruit that is messy. Common in the Old Southwest part of Reno. Tolerant of heat, cold, drought and poor soils. Leaves may tatter if planted on exposed sites in high wind areas. Very drought tolerant when it receives deep, occasional watering every 10-14 days. Not temperature sensitive and enjoys full sun, but can be wind sensitive. Does not need protection and is not disease prone.
