About

Rhus glabra, the smooth sumac (also known as white sumac, upland sumac, or scarlet sumac), is a North American species of sumac in the family Anacardiaceae.

Where it grows

It is native to North America, from southern Quebec west to southern British Columbia in Canada, and south to northern Florida and Arizona in the United States and Tamaulipas in northeastern Mexico.

Uses

Native Americans ate the young sprouts as a salad. The fruit is sour and contains a large seed, but can be chewed (to alleviate thirst) and made into a lemonade-like drink. Deer forage the twigs and fruit.
