Additional comments: Mexican redbud was classified by George Engelman (1809-1844), a physician and botanist from St. Louis, MO. Mexican red bud produces abundant brown seedpods that can create a litter problem. The name "redbud" is because the inner bark of this great small tree bears a reddish coloring. It was highly valued by Native American basket makers as a source of natural pattern contrast without the need to dye the fibers.

Cercis siliquastrum (Judas tree) is another excellent redbud that is well adapted to western gardens.
