Big Leaf Maple
Acer macrophyllum
  
About Big Leaf Maple (Acer macrophyllum) 30 Nurseries Carry This Plant Acer macrophyllum (Bigleaf Maple or Oregon Maple) is a large deciduous tree. It grows to be up to 35 meters tall, but more commonly 15-20 meters tall. The trunk can get up to a meter in diameter. It is native to western North America, mostly near the Pacific coast, from southernmost Alaska south to southern California. Some stands are also found inland in the foothills of the Sierra Nevada mountains of central California, and a tiny population occurs in central Idaho. It is winter deciduous, featuring large palmate leaves typical of maples. It produces nice fall color where temperatures become cold enough. It is very fast growing but may be too large for most residential gardens.
