Its natural coastal range extends from the extreme southern corner of Alaska to the southwestern corner of California. Another inland range occupies foothills of the Sierra Nevada. Bigleaf maple, Acer macrophyllum, is the most common and prominent native maple here. However, it prefers the seclusion of forested riparian situations at higher elevations locally. It is rare in urban gardens.
Bigleaf maple is best in the wild anyway. It dislikes the aridity of most of the urban and suburban areas of California. (San Jose is in a chaparral climate. Los Angeles is in a desert climate.) Roots of bigleaf maple are potentially aggressive, especially if irrigated generously. They easily displace pavement. Nonetheless, where climate and circumstances allow, bigleaf maple is a grand tree.
Wild trees grow as tall as a hundred fifty feet within forests where they compete for sunlight. Well exposed suburban trees should stay lower than forty feet, while extending their canopies broader than tall. The big and palmately lobed leaves are mostly more than six inches wide. Foliage turns yellow in autumn, and is abundant as it falls. Self sown seedlings often grow under mature trees.
