Hmmm, very pretty! This must not be a hardy maple variety though, right? I'd never heard of a maple vine before...thanks for sharing. :)

Vine Maple (Acer circinatum) is native to the west coast, from British Columbia down to northern California, & some distance inland. I think it's moderately hardy.

It has a vine-like habit when growing in deep shade, but in the open it'll grow into a tree, though I understand it's better if it's sheltered from hot afternoon sun.
