Cercis canadensis var. texensis 'Oklahoma' Cercis canadensis

Common Name(s):

  • Oklahoma Redbud
Description

Found growing in the wild in 1964 in Oklahoma, this small landscape tree is perfect for most Carolina gardens. ‘Oklahoma’ redbud has spectacular royal purple, pea-like flowers that emerge in early spring before the foliage appears. Perhaps its best trait is the thick glossy leaves that appear to be polished each day. The shiny leaves always draw attention to the tree, even by those unaccustomed to noticing trees.

Grow ‘Oklahoma’ redbud in well-drained soil in full sun or partial shade and water weekly. Avoid wet or poorly drained soil.  This beauty is very adaptable in Carolina landscapes and considered by some to be a “must have” small flowering tree. It is excellent for planting in lawns, woodland gardens, or in naturalized areas. It does not transplant well, so choose your location carefully. It is difficult to vegetatively propagate. Don’t miss an opportunity to dazzle your neighbors with this attractive tree.

There has been much debate over the distinction between Cercis canadensis var. mexicana and Cercis canadensis var. texensis.  Cercis canadensis var. texensis was formerly known as C. reniformis.  Morphologically, the two varieties are very similar and are often distinguished from one another based on geographic distribution.  More often than not, the leaf blade of C. canadensis var. mexicana exhibits an undulate margin where as the leaf blade of Cercis canadensis var. texensis is typically entire.  However, the geographic overlap of these characteristics make the taxonomic separation of these two varieties difficult to verify, as described by Fritsch et al. (2009).  

Insects, Diseases, and Other Plant Problems:  Japanese beetles, tree hoppers, leafhoppers, caterpillars, borers, webworms and scale. Canker. is a significant disease problem while verticillium wilt, leaf spots, mildew and blights are less frequent. This tree can suffer from damage caused by deer.
