Rhus glabra, commonly known as smooth sumac, is a deciduous shrub native to eastern North America. It typically grows to a height of 10 to 15 feet (3 to 4.5 meters) and has a spreading, open habit. The leaves are pinnately compound, consisting of multiple leaflets arranged along a central stem. Each leaflet is lance-shaped with serrated edges, giving the foliage a delicate appearance.
In spring, smooth sumac produces small, greenish-yellow flowers arranged in dense clusters at the tips of branches. These flowers are followed by the development of clusters of red, hairy fruit known as drupes. The fruit clusters, called "sumac bobs," are visually striking and persist on the plant throughout the fall and winter, providing a food source for birds and other wildlife.
Smooth sumac is known for its tolerance to a wide range of soil types and environmental conditions, making it a popular choice for naturalizing landscapes and controlling erosion. It prefers full sun to partial shade and is often found in open woodlands, fields, and along roadsides.
While smooth sumac is primarily valued for its ornamental qualities and ecological benefits, it has also been utilized for its medicinal properties and as a source of dye. Additionally, some Native American tribes historically used various parts of the plant for traditional purposes, including treating ailments and making beverages. However, it's essential to note that while smooth sumac has some traditional uses, caution should be exercised, as certain parts of the plant can cause skin irritation or allergic reactions in some individuals.
