Discussion

Varieties 4 (1 in the flora).

Fallopia japonica is planted widely as a garden ornamental; it has a proclivity to escape and spread aggressively. Once established, plants can be difficult to eradicate because of their extensive, woody rhizomes. The species has been declared noxious in Alabama, California, Oregon, Vermont, and Washington.
