Beautiful small clusters of purple and white flowers, which often bloom as other parts of the plant are producing large, (3 to 4 inches), green oval seed pods.

Drought-resistant, very salt-tolerant, and through its wind and animal dispersed seeds, it quickly becomes established as a weed along degraded roadsides, and in overgrazed native pastures. Has a preference for and is often dominant in areas of abandoned cultivation especially sandy soils in areas of low rainfall; it is often assumed to be an indicator of over-cultivation.
