About

Wisteria brachybotrys, the silky wisteria, is a species of flowering plant in the pea family Fabaceae from Japan. Some older references believed it to be of garden origin. It is widely cultivated in its native Japan, with the white flowered cultivars more widely grown than the pale violet cultivars. It is native to western parts of Honshu and throughout Shikoku and Kyushu, growing in mountain forests and woods from 100 to 900m.

The Greek specific epithet brachybotrys means "short clusters".
