Naturalistic woodland landscapes.

It's paint-chip white and brown-green bark provides winter interest. The natural range is from  north Florida into southern Canada.  This species has been planted well south of its range and is occasionally collected from places (such as the median of I-75, near old homesites,  and near mine reclaimation areas) where it likely got there due to man's activities.  It has also been widely planted in mined areas. Frequently used as a yard tree or as a shade tree in parks. Best used where its large size won't overwhelm the surroundings.
