American Ash (Fraxinus americana)-
Commonly called white ash, is the largest of the native ashes that typically grows to 60-80’ tall. Young trees are pyramidal in shape, but they will gradually mature to a more rounded canopy. Clusters of petal less purplish male and female flowers appear on separate trees in April through May before the late to emerge foliage. Fertilized female flowers give way to drooping clusters of 2” long winged samaras (they look like small flat oars) that ripen in fall and may stay on the tree during the winter. Features feather like compound leaves with 7 leaflets (less commonly 5 or 9 leaflets). Oval leaflets (3-5” long) are forest green above and sage green below. Foliage turns yellow with purple shading in fall. Gray bark develops a diamond shaped ridging on mature trees. ‘Autumn Purple’ is a common variety of the American ash.
Raywood ash (Fraxinus oxycarpa)-
This Ash is a finely textured deciduous tree that can reach up to 90 feet in height, but they will be more likely to stay at 40 to 50 ft tall with a 25 ft spread. Young trees are somewhat upright or oval eventually opening into a full, rounded canopy with age. The dazzling, dark green leaflets create a light shade underneath the tree, making it suited for a large lawn specimen or shade tree. The leaves turn various shades of red, purple and chocolate brown before falling in autumn.
