Smooth sumac


Anacardiaceae (Sumac Family)



Rhus glabra (Smooth sumac)
Loughmiller, Campbell and Lynn
The colony-forming smooth sumac is a 10-20 ft. shrub with short, crooked, leaning trunks and picturesque branches. The pinnately compound leaves are alternate, with 1330 sharp-toothed leaflets on each side of the midrib. Deciduous leaves become extremely colorful in early fall. On female plants, yellow-green flowers are followed by bright-red, hairy berries in erect, pyramidal clusters which persist throughout winter.

The only shrub or tree species native to all 48 contiguous states.

Soil Description: Most dry soils. Sandy, Sandy Loam Medium Loam, Clay Loam, Clay, Caliche type
Conditions Comments: This is the dominant sumac of blackland prairies. Plants of Rocky Mountain origin are usually separated into the variety cismontana. This dwarf variety is becoming popular in cultivation. In a planned landscape, the species is most effective when drifts or colonies, typical of natural settings, are allowed to establish. Colonies can be rejuvenated every few years by cutting them to the ground in mid-winter. Sumacs will grow in dry waste areas, such as impossible slopes where even junipers struggle. They are fast growing, generally pest and disease-free, and drought-tolerant. Colonies are often single-sexed, formed from a single, suckering parent. Only female plants produce flowers and berries.
