About

Acer circinatum, or vine maple, is a species of maple native to northwestern North America. Vine maple typically grows as a low-elevation coastal tree in temperate areas of high precipitation such as the west coast of Oregon and northern California, as well as the temperate rainforests of Washington and British Columbia. Vine maples play an important role in conserving the biodiversity of lowland ecosystems by enriching upper soil layers and providing habitat for other organisms.

How to grow it

It is occasionally cultivated outside its native range as an ornamental tree, from Juneau, Alaska, and Ottawa, Ontario, to Huntsville, Alabama, and also in northwestern Europe.

Where it grows

Acer circinatum can be found from southwest British Columbia to northern California, usually within 300 km (190 mi) of the Pacific Ocean, specifically along the Columbia Gorge and throughout coastal forests. It is found no further inland than the east side of the Cascade Range. Acer circinatum is most often found growing interspersed within conifer forests of Douglas fir (Pseudotsuga menziesii), Hemlock (Tsuga heterophylla), and Cedar (Thuja plicata). Vine maples are also known to occasionally establish small colonial gaps within conifer forests, where they proliferate after an overstorey disturbance (such as the death of a large tree), and are able to maintain the gap by preventing the re-establishment of larger trees.
