    This seedless, male cultivar has a uniform upright habit with an oval canopy. Fall color is a handsome orange-red. An unattractive ash flower gall (formed by mites) can develop on male flowers and persists into winter. Emerald Ash Borer is severely affecting all species of this genus. Damage can be prevented with the appropriate pesticide, but the treatment cost will eventually exceed replacement cost.
