Wood from white ash is commonly used to make tennis rackets, baseball bats and hockey sticks.
White ash is a common species in Ontario’s deciduous forests, throughout southern Ontario north to Lake Nipissing and Sault Ste. Marie. It grows to be the largest of our native ash species.
White ash is recognized by the diamond pattern of the maturing bark. White ash leaves are opposite and compound, with 5-9 but typically 7 leaflets, dark green on top and very pale below. Compared to green ash turning yellow, white ash leaves turn reddish-purple in fall and leave a notched leaf scar. White ash has small winged fruit that hang in clusters.
Like other native ash species once widely planted as shade trees, Emerald Ash Borer also threatens white ash throughout its range.
