Robinia x ambigua
Fairly fast growing plants, well adapted to hot, dry regions. Leaves are divided like feathers into many roundish leaflets. Clusters of white or pink, sweet pea-shaped flowers bloom from midspring to early summer, followed by bean-like pods about 4 in. long.
Locust trees tolerate poor soil and can get by on little or no water, but they do have some drawbacks: their wood is brittle, roots are aggressive, and plants often spread by suckers.Robinia x ambigua
