Distribution: The range of honeylocust extends from Pennsylvania west to South Dakota, Nebraska, south to Texas, east to Alabama and Georgia, northeast along the Appalachians to Pennsylvania.
The Tree: Honeylocust trees can reach heights of 80 ft (24 m), with a diameter of 3 ft (1 m).
General Wood Characteristics: The sapwood of honeylocust is yellowish and wide, while the heartwood is light red to reddish brown. The wood has no characteristic odor or taste. It is very heavy and very hard, tough, strong, with a high luster. The texture is moderately coarse, with straight to irregular grain.
