Botanical Name
Achyranthes japonica (Miq.) Nakai
Common Name
Japanese Chaff Flower
Flora of Virginia Name/Status
Not in Flora of Virginia; discovered after its publication.
Native to eastern Asia, Achyranthes japonica was first documented in the eastern U.S. in the 1980's. It is now known from at least nine states to the west and south of Virginia (ALA, GA, ILL, IND, KY, MO, OH, TN, WVA) and is especially well established in the Ohio River drainage. The plants introduced to North America apparently belong to var. hachijoensis Honda. Chaff Flower is a serious invasive threat to bottomlands and other low, wet habitats.
Discovered new to Virginia in 2022 by Nelson DeBarros; by a trail at the border of alluvial forest along the Potomac River west of Washington, D.C. A second sighting from approximately 1.5 miles downstream has been posted on iNaturalist, suggesting that the species is almost certainly more widespread along the Potomac.
