Eastern Redbud

Cercis canadensis
Common Name:
Redbud; Judas Tree

The most appealing feature of this tree is the showy flower, which is magenta in bud, but opens to rosy pink before the leaves emerge early in spring. The flowers appear in clusters that nearly cover the bare branches of the tree. They remain for two to three weeks. They usually appear in early spring after the white flowers of serviceberry and wild plum and before (and during) the white and pink flowers of the flowering dogwood.  Flowers are bisexual and the tree is self-pollinating. Pollination is usually accomplished by bees. The heart-shaped leaves are reddish as they emerge, and gradually turn dark green in summer. The fall color is yellow. Fruits are flat reddish-brown pods about 1/2-inch wide and 2 to 4 inches long. Each fruit contains 4 to 10 brown, hard, compressed bean-like seeds, each about 1/4-inch long. The fruits remain on the tree until after leaf fall; some persist throughout winter. Redbuds growing in the sun will be compact and rounded; when grown in shade, their form is loose, open and tall.

Culture
Grow in full sun or combination of sun and shade; prefers some shade in heat of summer. The Eastern Redbud grows in acidic, alkaline, loamy, moist, rich, sandy, well drained, wide range, clay soils. It prefers moist, well-drained soil. Does not like soils that are permanently wet.   Although it will grow in fairly dense shade, it blooms more heavily when exposed to sun. 

 

Use
Flowers provide nectar for bumblebees and several species of butterflies. This tree is best used in naturalized areas, and can also be used as a specimen or in groupings in a shrub border, bird gardens, or native plant gardens.

Additional Notes

 

George Washington reported in his diary on many occasions about the beauty of the Redbud and spent many hours in his garden transplanting seedlings obtained from the nearby forest.

 

Appreciated by early nectar-seeking insects. A variety of birds enjoy the seeds during winter.

 

Medicinal: Redbud has a long history of use as a food, dye, and medicine. Its flowers are high in Vitamin C and can be used as an attractive addition to salads and in pickled relish. The inner bark of the twigs will make a mustard-yellow dye. Various Native American nations have used redbud in medicinal remedies as well. They used the bark to brew a tea and used it to cure fever, relieve vomiting, and ease congestion.
