It is a small, deciduous tree with a spreading, flat-to-rounded crown. It can eventually grow to 20-30′ tall and the trunk usually divides somewhat close to the ground. Clusters of tiny, rose-purple, pea-like flowers bloom profusely on the branches and mature trunks for 2-3 weeks in early spring (March-April) before the foliage emerges.
