About This Species

This herbaceous annual species is often found growing in moist soils such as those around rivers, streams, and wetlands mainly in the Fraser Valley region. It is native to Asia. Although this species prefers moist soils, it is tolerant to a range of sun exposures, soil types, and climates, making it difficult to eradicate.
