When it comes to identifying a smooth sumac tree, there are several key characteristics to look out for. This shrub typically reaches a height of 10-20 feet and has short, crooked trunks with branches that have a picturesque appearance. The overall shape of the smooth sumac can vary, with some trees leaning slightly or having a more irregular growth pattern.
One of the most distinctive features of the smooth sumac is its leaves. They are pinnately compound, meaning that they are divided into multiple leaflets that are arranged in a feather-like pattern along a central midrib. On each side of the midrib, you can typically find anywhere from 13 to 30 leaflets. These leaflets are usually sharp-toothed, adding to the overall texture and appearance of the tree.
During the fall season, the deciduous leaves of the smooth sumac undergo a stunning transformation. They become extremely colorful, ranging from vibrant shades of red and orange to deep yellows and purples. This makes the smooth sumac a beautiful addition to any landscape during the autumn months.
In terms of growth habits, the smooth sumac has a unique way of colonizing. It forms colonies by spreading through underground rhizomes, which are horizontal underground stems. These rhizomes allow the tree to produce new shoots and establish new plants in close proximity to the parent tree. This can result in the formation of dense thickets or stands of smooth sumac, making it a great option for naturalizing an area or providing habitat for wildlife.
To summarize, identifying a smooth sumac tree involves looking for a shrub with short, crooked trunks and picturesque branches. The leaves are pinnately compound and have sharp-toothed leaflets arranged along a central midrib. In the fall, the deciduous leaves become incredibly colorful. Additionally, the smooth sumac has a unique growth habit of forming colonies through underground rhizomes.
