This deciduous tree bears stunning huge 6-15 inch wide lobed leaves that are green in the spring through summer and a spectacular shade of yellow in the fall. Native to the stream banks and wet canyons from Alaska south to southern California, it is often found covered in brilliant green moss in its home ecosystems. A fast grower (perhaps 10 feet in the first year!), it will reach 30-75 feet in height and 30-50 feet wide in optimal conditions. Most often it tops out at 30 feet. Bigleaf Maples require consistent and deep watering in their first year, particularly when planted in a dry region. It is drought tolerant once established and will tolerate clay soils well. Small yellow flowers are pendulous with 10-30 borne on a showy panicle or raceme. These become brown seeds that hang in clusters from the branches. This species is an excellent shade tree, well-suited to use in a lawn or other well-watered area and is happily resistant to oak root fungus.
