Sumac is a native plant of Kentucky. Some varieties grow ten feet in height, and although their berries are poisonous to humans, they are a delectable treat for birds and animals alike.
In early times there was a prolific growth of sumac along Severn Creek (spelled Savern in old deeds). Some of the settlers referred to the stream as Sumac Creek, but it was more commonly called Severn. It is thought that the name most likely was to honor Ebenezer Severns who, along with Hancock Taylor and Jacob Drennon, surveyed the area in 1773.
