A North American native maple found in habitats from Alaska to southern California. As the name implies plants have huge dark green leaves often exceeding 12" in breadth. Leaves are supported on strong, glaborous stems and branching that can rise to 50' or more when mature. Plants are at their best in stress free environments that see limited heat and drought stress. Though the straight species is rarely cultivated on the east coast we find that the cultivars have special merit for texture and color.
