Fraxinus pennsylvanica 'Marshall’s Seedless'

Marshall's Seedless Green Ash

This cultivar is marketed as seedless, but there have nonetheless been many females in the population with heavy fruit set. This tree is quite adaptable and fast growing, but also has weak branch angles. 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.
