Rhus glabra - scarlet, smooth, or upland sumach
Scarlet sumach is native to North America, mainly the eastern parts of the continent, but can be found in almost every state of the Union, as well as in southern Canada. It is a suckering tree or shrub which thrives in full sun on sandy slopes and roadsides. One of the common names refers to the hairless branches, which are the best distinguishing mark from its near relation, the stag’s horn sumach (R. typhina).
