Phonetic Spelling:SER-sis GLAY-bruh

Genus:Cercis

Species:glabra

Family:Fabaceae

The Smooth Redbud thrives in a variety of environments, including dense forests, mountainous terrains, and valley areas near roads, as well as rocky sites. Its genus name, Cercis, is derived from the Greek term "kerkis," which translates to "weaver's shuttle," a nod to the resemblance of its seed pods to the size and shape of the tools used in weaving.

In spring, before the leaves emerge, this tree showcases abundant clusters of flowers, characteristic of other redbud species.

It is also known by the synonym C. yunanensis.

Wildlife Benefits: The flowers of the Smooth Redbud are a source of nectar for bees, and once pollinated, they develop into leguminous pods that birds can eat. Additionally, the genus Cercis is known to support the specialized bee species Habropoda laboriosa.

Pests, Diseases, and Other Issues: This tree may experience damage from deer.

Growth Habit: It typically has an upright, vase-like form and a shrubby appearance.
