Garden Uses: Eastern redbud is native to the eastern and south-central United States and all regions of Maryland, except for a few counties nearest our Atlantic coastline. Its natural habitat includes forest edges, woodlands, and stream banks. It prefers well-drained, moist-to-occasionally dry soil. It does not tolerate wet, poorly aerated, or coarsely sandy soil conditions.
Showy pink flowers open in late spring before the leaves emerge. The heart-shaped leaves turn yellow in the fall. Pea-like seed pods are brown-black and may remain on the tree during the winter. Self-sows. Susceptible to Verticillium wilt, Botryosphaeria canker, and leaf anthracnose.
Use as a small specimen tree in a yard, woodland, or pollinator garden. This tends to be a short-lived tree (20-30 years). Plant trees in succession for replacement.
Wildlife: Many bees are supported by the nectar and pollen provided by the flowers of Eastern redbud. Some butterflies will feed on the nectar as well. This is a host plant for several species of moths, including the Io Moth and the White-Marked Tussock Moth. Some songbirds, such as Northern Cardinals, eat the seeds.
