Flowers/fruit: Flowers perfect, white, 1" to 1-1/4" long, pea-like, fragrant; borne in large, drooping groups in May to early June; very attractive. Fruit a 2" to 4" long, 1/2" wide legume; brown; maturing in October; contains 4 to 6 brown, flat, very hard seeds.

Bark: Very smooth and gray on young and old branches and the trunk.
