Characteristics
The name White Ash derives from the glaucous undersides of the leaves. It is similar in appearance to the Green Ash, making identification difficult. The lower sides of the leaves of White Ash are lighter in color than their upper sides, and the outer surface of the twigs of White Ash may be flaky or peeling. Green Ash leaves are similar in color on upper and lower sides, and twigs are smoother. Also, these species tend to occupy different habitat niches, with White Ash found in moist upland sites and Green Ash in wet forests of floodplains or swamps, although there is some overlap in habitat distribution.
