‘Oklahoma’ is even more compact and broad-rounded than Cercis canadensis var. texensis, typically maturing to 12-18’ tall. It is more commonly sold in commerce than var. texensis in large part because its flowers are darker (rosy magenta to wine red) and its leaves are a richer green with more gloss and wax. ‘Oklahoma’ was discovered growing wild in the Arbuckle Mountains of Oklahoma in 1964.
Var. texensis, synonymous with and formerly known as Cercis reniformis, is a variety of eastern redbud that is native to Oklahoma and Texas. It typically has a shrubbier, more compact form than the straight species with a mature height of 15-20’ tall. It differs from the straight species by having (1) slightly more drought tolerance, (2) darker and brighter wine red buds and flowers, (3) glossier, thicker, broader and darker green leaves often with a more reniform (kidney-shaped) outline, (4) leaf apices that are rounded or blunt (not pointed) and (5) winter hardiness to USDA Zone 6 (species to Zone 4).
