Culture
Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Part shade is best in hot summer climates. Performs best in moderately fertile soils with regular and consistent moisture. Avoid wet or poorly drained soils. Since this tree does not transplant well, it should be planted when young and left undisturbed.
Noteworthy Characteristics
Cercis canadensis, commonly called eastern redbud, is a deciduous, often multi-trunked understory tree with a rounded crown that typically matures to 20-30’ tall with a slightly larger spread. It is particularly noted for its stunning pea-like rose-purple flowers which bloom profusely on bare branches in early spring (March-April) before the foliage emerges. This tree is native to eastern and central North America from Connecticut to New York to southern Ontario and the Great Lakes south to Western Texas and Florida. It is found in open woodlands, thickets, woodland margins, limestone glades and along rocky streams and bluffs throughout Missouri (Steyermark). Flowers (to ½” wide) bloom in clusters of 4-10. Flowers are followed by flattened leguminous bean-like dry seedpods (to 2-4” long) that mature to brown in summer. Each pod has 6-12 seeds. Pods may remain on the tree into winter. Alternate, simple, cordate, broadly ovate to nearly orbicular, dull green to blue-green leaves (3-5” across) have a papery texture and are short pointed at the tip. Leaves turn pale yellow to greenish-yellow in fall. The flowers provide an early-season nectar source for hummingbirds. The seeds and flowerbuds are eaten by songbirds. Caterpillars and other insects which feed on redbeds are also a source of food for birds.
Genus name comes from the Greek word kerkis meaning "weaver's shuttle" in reference to the resemblance of each seed pod to a weaver's shuttle.
Specific epithet is in reference to Canada (southern Ontario) being part of the native range of this tree.
'Forest Pansy' is a purple-leaved cultivar of the popular Missouri native redbud tree. Fall color is variable, but often includes attractive shades of reddish-purple and orange.
Problems
Canker can be a significant disease problem. Verticillium wilt, dieback, leaf spots, mildew and blights may also occur. Insect pests include Japanese beetles, tree hoppers, leaf hoppers, caterpillars, borers, webworms and scale. Keeping the tree vigorous by regular watering, fertilization and pruning out dead branches as needed will help keep the tree healthy. Deer tend to avoid this plant.
Uses
Specimen or small groups. Lawns, shrub borders, woodland margins, or along patios. Street tree or lawn tree. Attractive in naturalized settings. Good cut flower for forcing indoors.
