Wisteria is common where I live but it’s a vine not a tree, though the vine often is grown next to a tree so that it eventually drapes the tree. I wonder if the wisteria “tree” in Japan is actually the wisteria vine grown next to the tree or is a vine that has been pruned so that it actually became a tree?
Wisteria is a vine. The native Japanese and native American versions are different species, but you’d have to delve deeper into the fine print in the wiki articles than I care to to find the differences.
These both twist up to the right, but yamafuji (literally “mountain wisteria” (Wisteria brachybotrys)) twists to the left.
Here in Japan, the Japanese love their wisteria. Being from Boston (which may be a bit chilly for wisteria), I prefer lilac, but wisteria will do in a pinch. Wisteria grows on trees in nature, but is usually provided with an artificial support when used in Japanese gardens, as in all the photos at the link in the original post.
