Cimmaron ash is a large deciduous tree that is more upright and columnar than regular green ash. Shiny green leaves turn to reddish-purple in the fall. It is a seedless cultivar. Due to the presence of the emerald ash borer in Colorado, tree care professionals are no longer recommending ash trees be planted in Colorado.

This is a widely planted tree in the Colorado Springs area since it has been a reliable, attractive tree.

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.
