Eastern Redbud (Cercis canadensis) flowers. 

Eastern redbud is a native, perennial, deciduous tree or shrub.  The plants may vary in form from dense and round (to 6 m tall) when grown in sun, to an open, taller form (to 12 m tall) when grown in the shade.

The trees produce hundreds of small pink pea flowers in the very early spring, even before other trees have leafed out.  The bright magenta-pink to lilac flowers, appear in small clusters, primarily on older stems.  The unique, broadly heart-shaped leaves are nearly circular.  New leaves are a light green that darken with age and finally turn yellow in the fall.  The seeds are contained in a flat, thin pod, which turns from green to brown.

Common name: Redbud

Scientific name: Cercis canadenesis

Attracts: Many birds, including bobwhite quails, eat the seeds.  White-tailed deer are among the animals that browse the foliage.  Honeybees visit the blossoms.  Livestock will browse on Eastern redbud.

Growing Tips:
The plants require very little maintenance. Eastern redbud has relatively few pests.  Stem canker, leaf spots, and verticillium wilt may be a problem.  The plants may experience some insect damage from leaf rollers, treehoppers, scales, leafhoppers, aphids, and spider mites, but damage is rarely severe.

Cuttings are difficult to root.  Mature plants do not transplant well so buy young plants that are balled-and-burlapped or container grown.  Transplant the plants in the spring or fall, in well-drained soils in sun to part shade.  Water the plants regularly until established.

Ethnobotanic: The Alabama, Cherokee, Delaware, Kiowa, and Oklahoma were among the Native American tribes that used eastern redbud for various purposes.  The bark was made into a tea to treat whooping cough.  Taking cold infusions of the roots and inner bark treated fevers and congestion.  An infusion of the bark was used to treat vomiting and fever.  During winters, the plants were used for firewood.  Because it is one of the first plants to flower in the spring, the blossoming branches were brought into the homes to “drive winter out.”  Children were “fond of eating the blossoms” of eastern redbud.
