Selected cultivars:

Eastern redbud is a very variable species, partly because it has such a wide geographical range.

• ‘Alba' - Plants sold under this cultivar name may be vegetatively propagated, but usually they are white seedlings (technically a botanical variety - var. alba). Flowers are pure white and provide clouds of white flowers in the early spring.
• ‘Covey' - A unique weeping form of eastern redbud. ‘Forest Pansy' - Rounded form, 20 feet tall and 25 feet wide. Has reddish branches that are horizontally tiered, and pink flowers before leafout in spring. Heart-shaped leaves are a brilliant scarlet-purple, then mature to maroon.
• ‘Silver Cloud' - Is a variegated leaf form of redbud. New leaves are splotched with white markings. Partial shade prevents leaf burning. Introduced by Theodore Klein from Kentucky.

Good pink cultivars of redbud include:

• ‘Flame' - A double-flowering form. ‘Pinkbud' - Has bright pink flowers.
• ‘Rubye Atkinson' - Smaller flowers than the species, but a clear pink.
• ‘Tennessee Pink' - Rounded form, with clear pink flowers.

Botanical varieties

Not only are there numerous cultivars of redbud, but there are several botanical varieties that are distinctive.

• C. canadensis var. alba - Plants sold under this cultivar name may be vegetatively propagated, but usually they are white seedlings (technically a botanical variety - var. alba). Flowers are pure white and provide clouds of white flowers in the early spring.
• C. canadensis var. mexicana - Has shiny leaves with wavy margins. Leaves range in size from 1 to 6 inches in diameter. Flower color is much like that of the species. Thought to be hardy in Zones 6 to 9.
• C. canadensis var. texensis - Found in Texas, Oklahoma and Mexico, this variety is considered adaptable in Zones 6 to 9. Includes ‘Oklahoma' and ‘Texas White,' both with shiny green leaves. ‘Oklahoma' has rosy magenta flowers; ‘Texas White' has white flowers. These trees usually reach a height of 15 to 25 feet with a similar width. They are adaptable in Zones 6 to 9.

Additional information:
Eastern redbud starts flowering when it is 4 to 6 years old. The flowers bloom in early spring before leafout. Flowers are often found on the trunk. The bark of eastern redbud is brownish black and scaly. On older trees, the orangish inner bark can often be seen. Bark becomes fissured as the tree ages. Folk healers used the bark of eastern redbud to treat diarrhea and leukemia. Native Americans used the wood of a similar species, Cercis. occidentalis, the western redbud, to make bows.

Redbud has been called the Judas tree because Judas Iscariot, after betraying Christ, was said to have hanged himself on Cercis siliquastrum, a close relative of eastern redbud that grows in Europe and western Asia. The blooms of the tree, originally white, were said to have turned pink with shame or blood.

In Mexico, the flowers of redbud are fried and eaten. John Lawson wrote of redbud flowers being used in salads in his History of North Carolina, published in 1708. Redbud is the state tree of Oklahoma.
