With enormous lobed leaves up to 15 inches across, there's no doubt where the common name Bigleaf Maple came from! Acer macrophyllum is a magnificent large shade tree native to the western United States, where it thrives in naturally moist areas such as along streambanks and around other bodies of water. A fast grower adding up to 3 feet in height and width per year, although it can reach upwards of 100 feet tall in perfect conditions, 40 to 60 feet tall and equally as wide is more common in residential and commercial landscapes, so make sure to give it plenty of room to grow. The leaves emerge burgundy-red in spring, becoming bright to rich green during the warm season, turning to striking yellow during the fall, contrasting beautifully with the brown-winged samaras. The Bigleaf Maple is an excellent tree that provides dense summer shade and outstanding fall color in areas where it will grow; USDA Zones 6a-8b in cool summer climates and not below 7b where summers are hotter. It also supports wildlife by providing food for birds, small mammals, and mule deer. Get all the details below
