Cercis canadensis var. texensis 'Oklahoma'
SER-sis kan-a-DEN-sis tex-EN-sis
Cercis reniformis ‘Oklahoma’
C. c. var. canadensis 'Oklahoma'
Native to (or naturalized in) Oregon:
- Deciduous tree, 15-25 ft (4.5-7.5 m) tall, similar width, rounded. Leaves simple, alternate, to 7 cm, leathery, glossy green, with undulating margins. Flowers are wine red. Fruit (pods) to 10 cm long.
- Hardy to USDA Zone 6 C. c. var. texensis is found in Oklahoma, Texas and Mexico, however there is "no clear-cut differences in the range among Texas [C. c. var. texensis] and Mexican [C. c. var. mexicana] redbuds" (Raulston, 1990). Some authorities consider that the two varieties represent environmentally induced morphologies (i.e. more leathery leaves in more xeric conditions) and lump both under C. c. var. canadensis. In any case, the 'Oklahoma' selection was discovered in 1964 in the Arbuckle Mountains of Oklahoma. It was named and released by Warren & Son Nursery, Oklahoma City, in 1965. Some considered it to be a superior redbud, but unfortunately it is somewhat difficult to vegetatively propagate.
