Autumn Purple® Ash

Autumn Purple® is a male, seedless selection of white ash with a dense, rounded crown and a showy autumn display. Its dark green compound leaves can turn mottled orange-yellow, deep purple, or mahogany, and full sun tends to strengthen the fall color. [Oregon State University’s profile](https://landscapeplants.oregonstate.edu/plants/fraxinus-americana-autumn-purple) records the cultivar identity as 'Junginger' and lists a mature size of about 40 feet tall by 25 feet wide. ## Siting and Growth Plant in full sun for the best fall color. Deep, moist, well-drained soil supports strong growth; the tree is hardy to USDA zone 4. Its broad rounded crown needs open space away from buildings and overhead wires. ## Landscape Use Use it as a shade tree or specimen where the fall foliage can be seen. The cultivar is male and seedless, so it does not produce the winged seeds associated with female ash trees. ## Maintenance Allow room for the mature canopy and remove damaged or crossing branches as needed. The cited cultivar profile does not prescribe a special pruning schedule.
