Vine maple, also known as Acer circinatum, is a deciduous shrub or small tree native to the Pacific Northwest region of North America. This plant is characterized by its unique, circular-shaped leaves and twisty branches. While vine maple is a popular name for this species, there are also a number of synonyms that describe this plant. Some of these synonyms include roundleaf maple, Oregon maple, mountain maple, and western maple. These alternative names reflect the diverse range of environments where vine maple can be found, from the high elevations of the Rocky Mountains to the coastal forests of Oregon and Washington.
