Nitrogen fixing, colony-forming, plant with semi-woody erect, sparsely branched stems and blue-green leaves. Stems are topped with a spike of creamy white pea flowers in spring. Blooms are followed by inflated seed pods that turn black when ripe. A deep tap root makes this plant tolerant of dry soils and extended periods of drought.
