Bigleaf maple
Acer macrophyllum 路 Sapindaceae 路 also Oregon maple
The largest maple in North America, with the biggest leaves of any maple (up to a foot across) that emerge burgundy, mature glossy green and turn yellow-orange in fall. Hanging chains of yellow-green flowers in spring become winged seeds. In wet coastal forests its limbs are draped in moss and licorice fern. It is a grand shade tree for large lots and parks but its shallow roots crack sidewalks and its leaf fall is heavy.

Care
Plant in sun or part shade in moist, well-drained soil and water through dry summers for the first few years. Prune in summer or when fully dormant, not in spring when sap flows. It has few serious pests; older trees develop heart rot, and verticillium wilt and aphids occur. Give it room away from pavement.
