Autumn Purple ash is a medium size shade tree grown for the striking purple color of its leaves in fall. It develops a uniform, rounded crown as it matures. Due to the presence of the emerald ash borer in Colorado, tree care professionals are no longer recommending ash trees be planted in Colorado.

There is a beautiful autumn purple ash growing at the Xeriscape Garden. It has a moderate growth rate and a uniform, rounded shape. The fall color is very attractive.

Prune when young to achieve a structurally sound tree. For existing trees, protect them from emerald ash borer once the insect is found within a 50 mile radius. It is currently limited to the Boulder/Denver area.
