- Description
-
This variety is not widely available nor is it recommended for NC gardens. Please consider planting Cercis canadensis and its cultivars.
Mexican redbud is a woody, deciduous, perennial shrub or tree in the Fabaceae (bean) family that can grow 11 to 15 feet high and 11 to 15 feet wide. It has a dense rounded crown. This redbud is native to southwest Texas to northeastern Mexico. The genus name Cercis comes from the Greek word kerkis which means weaver’s shuttle, referring to the seed pod resembling the size and shape of a weaver’s shuttle which is used to move thread back and forth on a loom. The common name redbud comes from its inner bark that bears a reddish color.
It grows best in all types of soil, including shallow rocky areas, that have good drainage and are occasionally dry. Plant in full sun to partial shade. Propagation is recommended by seed or stem cutting.
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 var. mexicana exhibits an undulate margin whereas the leaf blade of var. texensis is typically flat.
Plant Mexican redbud in areas of the landscape where its showy, pea-like spring flowers will be enjoyed. It does well in butterfly, pollinator, native, and drought tolerant garden themes. Mexican redbud does well with numerous design themes and attracts bees, butterflies, and birds.
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 seed pods can create a litter problem.
