Oklahoma State Tree

Eastern Redbud

(Fabaceae Cercis canadensis)

Adopted in 1937; June 24, 1971

The Eastern Redbud, Fabaceae Cercis canadensis, was adopted in 1937 as the Oklahoma state tree. The Eastern Redbud grows in the valleys and ravines of Oklahoma. In early spring, its reddish-pink blossoms brighten the landscape throughout the state.

Description of the Oklahoma State Tree

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.
