Rhus glabra (Smooth Sumac) Unity Grown

Known for its wildlife value and ornamental berry clusters, Rhus glabra, also called smooth sumac, is a large shrub or small tree that grows to 10-20' tall and wide, forming thickets over time. Slightly smaller than its better known relative staghorn sumac (Rhus typhina), smooth sumac is set apart by its smooth young stems and slightly glossier green leaves than staghorn sumac, as well as its smaller size. Though occasionally considered a weedy tree with its suckering growth habit, Rhus glabra makes for an excellent addition in large, naturalized hedges, woodland borders, or in disturbed bank areas where it can be used for erosion control purposes.

Commonly found in riparian buffer areas near streams and in disused agricultural fields, smooth sumac grows best full sun to partial shade and in medium-dry soils, but tolerates a wide variety of soil conditions so long as its in a well-draining spot; due to its natural site preferences, smooth sumac tolerates erosion, drought and dry soil, nutrient poor locations, and soils polluted by black walnut. While lower plants parts are resistant to rabbit damage, leaves and young branches may still be eaten by deer, which may impact its showiness, especially during the fall when leaves turn to showy orange and red tones. Aside from feeding deer, small and insignificant sumac flowers are a great nectar source for a variety of bees and butterflies in the early summer, and the plant's dense clusters of red, sticky berries are an excellent food source for a number of bird species from summer well through the winter. With a ton of wildlife value and a ton of ornamental value, Rhus glabra is a wonderful and underutilized plant for the home landscape and restoration projects.
