The Eastern Redbud, (Fabaceae Cercis canadensis,) was adopted in 1937 by Senate Bill 143 as the Oklahoma state tree. The Eastern Redbud, native to North America, grows in the valleys and ravines of Oklahoma. In early spring, its reddish-pink blossoms brighten the landscape throughout the state. Genus name comes from the Greek word kerkis in reference to the resemblance of seed pods to a weaver's shuttle.
Eastern redbud is a small, short-lived deciduous tree found throughout the eastern United States. Redbud is also known as Judas-tree. According to legend, Judas Iscariot hanged himself from a branch of the European species (Cercis siliquastrum.) Eastern redbud is a strikingly conspicuous tree in the spring because it flowers before other tree leaves form. The wood is heavy, hard, and close-grained, but because of the small size and irregular shape of the tree it is of no commercial value as a source of lumber. This tree is most valued as an ornamental and is extensively planted.
The state tree of Oklahoma, Eastern Redbud is a moderate to rapid-grower when young, reaching a height of 20 to 30 feet. Thirty-year-old specimens are rare but they can reach 35 feet in height forming a rounded vase. Trees of this size are often found on moist sites. The splendid purple-pink flowers appear all over the tree in spring, just before the leaves emerge. Eastern Redbud has an irregular growth habit when young but forms a graceful flattopped vase-shape as it gets older. The tree usually branches low on the trunk, and if left intact forms a graceful multitrunked habit. Yellow (although somewhat variable and unreliable) fall color and tolerance to partial shade make this a suitable, attractive tree for understory or specimen planting.
