Robinia x ambigua
These fairly fast-growing trees are 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 the plants often spread by suckers.Robinia x ambigua
