Twiggy branches of a mature hackberry tree
Hackberry (Celtis occidentalis) is a tree that's quite easy to identify in winter. If you learn to recognize its amooth-but-warty bark and its extremely twiggy silhouette, you can name this tree with confidence.
Celtis occidentalis, the common hackberry, grows in most of the United States except for the states west of the Rocky Mountains (Those states have other varieties of hackberry trees.) It produces small berries (actually, drupes) that are eaten by a wide variety of wildlife. Because of the sweetness of the berries, one of hackberry's common names is "sugarberry".
This tree grows on the grounds of St. Peter and Paul Catholic Church in Hopkinsville, Kentucky. It's a very large tree. I am fond of it.
