Cercis canadensis var. mexicana
Common Name(s):
- Phonetic Spelling
- SER-sis kan-ah-DEN-sis
- Description
-
Sometimes listed as C. mexicana or C. canadensis ssp. mexicana.
The Mexican Redbud can be found growing in its native habitat in the limestone soils around the shaded canyons and slopes from southwest Texas into northern Mexico. The name redbud come from its inner bark that bears a reddish color.
There has been much debate over the distinction between Cercis canadensis var. mexicana and Cercis canadensis var. texensis. 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 whereas the leaf blade of Cercis canadensis var. texensis is typically flat. 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).
The genus name Cercis comes from the Greek word kerkis which means weaver's shuttle, referring to the fact that the seed pod resembles the size and shape of a weaver's shuttle used to move thread back and forth on a loom.
Wildlife Value: The flowers provide nectar for bees and once pollinated form leguminous pods, the seed can be consumed by birds. Members of the genus Cercis support the following specialized bee: Habropoda laboriosa.
Insects, Diseases, and Other Plant Problems: Leaf cutter bees can damage the foliage. Root rot and stem rot can appear on trees grown in moist or poorly drained soils. This tree can suffer from damage caused by deer. The falling seedpods can create a litter problem.
