'Green Mountain' Sugar Maple is a popular and well-established cultivar that has a broad pyramidal form. It is noted for its rapid growth rate, straight central trunk branching to a narrow ovate head, thickened and strong crotches, thick deep green foliage and resistance to leaf hoppers and leaf scorch. Deeply cut, leathery, dark green leaves turn excellent shades of orange and scarlet in fall. Pale yellowish-green flowers appear in clusters in spring before the leaves emerge. Maturity: 40'-60' tall. Zones 4-8.
