Eastern redbud – Cercis canadensis – is small, graceful tree native to the eastern and central United States.
It is typically found in open woodlands, thickets, woodland margins, and along streams and bluffs, often on limestone soils. It blooms before and as the leaves emerge, with rosy-pink, pea-like flowers that are borne in fascicles of four to eight. The flowers are held close to the branches, and even bloom along the trunks, clothing almost every inch in bloom. Trees may be trained to a single trunk or grow multi-stemmed. Eastern redbud has a flat-topped to rounded growth habit, and large heart-shaped leaves.
Fall foliage color is variable, but can be a good, clear yellow. Eastern redbud is in the Fabaceae (legume) family, so the fruits are brown to black pods typical of that family. While most members of the legume family are able to fix nitrogen from the atmosphere, eastern redbud lacks the nodules and bacteria necessary for that process.
Eastern redbud grows 20-30 feet tall and 25-35 feet wide, making it a suitable choice for small landscapes. It grows best in full sun to part shade and evenly moist, well-drained soils, but is adaptable to most soils as long as drainage is good. It is also tolerant of acid or alkaline soils. Eastern redbud is hardy in USDA Zones 4-9.
Use as a specimen, patio or lawn tree, in small groups or naturalized plantings. Eastern redbud is excellent with spring-flowering bulbs such as daffodils and tulips that are in bloom at the same time.
