Eastern Redbud

Cercis canadensis (SER-sis kan-a-DEN-sis)

Family: Fabaceae Native Understory (15-40 ft)

Eastern redbud is a deciduous, ornamental tree in the bean family (Fabaceae). It is native to eastern North America and may grow up to 20 to 30 feet tall and 20 to 35 feet wide. It is a small tree that is often found growing beneath taller trees. The genus name Cercis comes from the Greek word kerkis , which means weaver's shuttle, referring to the fact that the seed pod resembles the size and shape of a weaver's shuttle used to move thread back and forth on a loom. The tree is pH adaptable and can tolerate full sun or part shade and moderately fertile clay or sandy soil. It does not tolerate heat or drought, which can stress the tree, or wet soils. It does not tolerate root disturbance, so plants should be placed in their permanent positions as soon as possible and should be kept well-watered until established. Because its branches tend to break, the tree should be sited in a relatively protected area. Regular watering, fertilization, and pruning out dead branches as needed will keep the tree vigorous. Eastern redbud is a flowering tree that blooms before the leaves appear. In early spring, clusters of rose pink to light purple flowers mature and attract many pollinators, including butterflies, and bees. Members of the genus Cercis support the specialized bee Habropoda laboriosa . The plant holds great wildlife value as a larval host plant. Plant this tree as a specimen in a pollinator garden, as an understory tree in a wooded landscape, in small groups, or mass planted for a dramatic springtime effect. It may also be planted as a street or lawn tree but is very sensitive to herbicides and chemicals sprayed on lawns. Insects, Diseases, and Other Plant Problems: Insect pests include leafhoppers, caterpillars, borers, Japanese beetles, treehoppers, scale, and webworms. Possible diseases include canker, dieback, leaf spots, verticillium wilt, blights, and mildew. It can be a short-lived plant, typically living less than 75 years.

Flower detail
Conspicuous bright-red flowers bloom in early spring (around April) and are anywhere from pink to red to purple in color. Unlike many other plants, the flowers are seen before the leaves. Only about 1/2 inch wide and having about 7 flowers in a cluster, these flowers grow right on new stems as well as older branches. Pea-shaped flowers, borne in tight clusters on old wood, fascicled or racemous, often cauliflorous. Blooms from March to May.

Fruit detail
By summer (after flowers) but possibly lasting through fall and even winter, this plant has green turning to brown, flat, oblong seedpods (with about 9 seeds per pod) which are about 2 to 4 inches long. The brown seed pods can look a little untidy hanging from the tree into the winter.
Bark color
Black; Dark Brown; Orange
Bark detail
Dark brown to black with orange inner bark that can be visible. Smooth when young, but developing long, narrow plates that separate into scales as the tree matures.

New Mexico north to Nebraska, east to Michigan and Ontario, south through Pennsylvania and Massachusetts to Florida.
Wildlife value
12 species of Lepidoptera use this tree as a larval host plant. Leafcutter bees (such as Megachile rotundata) and other bees use this plant (as shown in a picture). Host plant for Henry's Elfin butterfly. Butterflies and other insects nectar from the flowers. Caterpillars appear from February to May and have one flight. Adult Henry's Elfin butterflies feed on flower nectar. Songbirds and small mammals occasionally eat the seeds.

Edibility

The flowers are edible and taste similar to peas. Contain high amounts of vitamin C.

Uses (ethnobotany)

Wood is heavy, hard, but not strong with little commercial value. The bark used as an astringent in treatment of dysentery, flowers eaten in salads or fried, Native Americans boiled the bark to make tea to treat whooping cough, roots and inner bark used for fevers, congestion, and vomiting.
