Sumac (Rhus sp.)
There are 54 species of Sumac in North America, and most of them are considered junk or weed trees and shrubs. Sumacs are very common in the wild along highways, in the medians of interstates, and in farm fields that have recently been abandoned. However there are three species of Sumac that have made their way into the ornamental landscaping field. Shining Sumac (Rhus copallina), Staghorn Sumac (Rhus typhina), and Smooth Sumac (Rhus glabra) are small trees or shrubs that are used in certain applications in the home landscape. Fragrant Sumac (Rhus aromatica) is also used but is a shrub growing no more than 6 feet tall, so we will not discuss that plant here.
