Description:
Of the ash in Minnesota, the blue ash is the easiest to identify due to the square edges of the branches (square cross-section). The foliage of the blue ash turns from a dark green to a pale yellow in the fall. Due to the emerald ash borer's spread across Minnesota it is not advised to plant this species of ash.
