Acer macrophyllum

Small to large tree with broad, rounded crown of spreading or drooping branches and the largest leaves of all maples. Big-leaf maple is usually a 20-75 ft. tree. Though it occasionally reaches 100 ft., it is generally much smaller in cultivation. Lateral branches soar upward from the massive, squat trunk, becoming huge, vertical limbs in older specimens. The bark is gray to reddish-brown and furrowed. Dark, glossy-green, deciduous foliage, often more than a foot in width, turns yellow-orange in fall. The common and scientific names describe the very large leaves.
