Comment:

Rhus glabra, commonly called smooth sumac, is a deciduous shrub which occurs on prairies, fields, abandoned farmland, clearings and along roads and railroads throughout the State. It is a large, open, irregular, spreading shrub which typically grows 8-15' tall and spreads by root suckers to form thickets or large colonies in the wild. It is very similar to staghorn sumac (R. typhina), except the young stems of staghorn are densely pubescent whereas those of this species are smooth, hence the common name. The bark is smooth and light brown with numerous lenticels when young.  Large, thin scales develop as the tree ages.

It can be rejuvenated by cutting to the ground every few years.  Smooth sumac is acolony forming shrub.
