Rhus glabra L.
Anacardiaceae (Sumac Family)
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 13–30 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
to all 48 contiguous states.

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.
The seeds remain firmly attached for a long time without noticeable deterioration and are often used in large decorative arrangements. Use Wildlife:
Consumed by birds of many kinds and small mammals, mainly in winter. Deer browse the twigs and fruit
throughout the year. Use Food:
Raw young sprouts were eaten by the Indians as salad. The sour fruit,
mostly seed, can be chewed to quench thirst or prepared as a drink similar to lemonade. Use Medicinal:
as a remedy for pianful menstruation and blood diarrhea. Diuretic. Roots and berries steeped to make wash for sores. Internal as a tea and externally as a wash for female complaints. (Kindscher) Use Other:
Roots make yellow dye. Mixed with tobacco to smoke. (Kindscher) Conspicuous Flowers:
