Green Ash - Fraxinus pensylvanica
Growing north into the Canadian prairies and Maritimes, this is the most northerly distributed ash on the continent. It grows west to Montana and south to the Florida panhandle. It is a species of wet places and, owing to its rapid growth rate, is widely planted, often used for revegetation; however, it is subject to decimation by the Emerald Ash Borer, a beetle. The leaves are nearly a foot long with typically 7 leaflets; they are bright green above, sometimes hairy beneath. The fruit is a narrow samara, borne in clusters. The wood is considered excellent for musical instruments.
