ROBINIA

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

A hybrid between Robinia pseudoacacia and R. viscosa, this seldom-grown, pink-flowering locust grows 40 ft. tall and nearly as wide. Its varieties are better known.
