Species Biology

Identification

Deciduous vine-like perennial, similar in appearance to bindweed, generally vigorous forming a mass of greenish red stems, 5-10m long (Booy et al., 2015).

Ecology

No studies to date are available on the ecology or impacts of Fallopia baldshuanica in its introduced range. Has the potential to outcompete native plants by vigorous growth (Booy et al., 2015).

Habitat

Grasslands and landscapes dominated by forbs, mosses or lichens; Heath, scrubland & tundra; Woodland, forest and other wooded land; Inland unvegetated or sparsely vegetated habitats; Regularly or recently cultivated agricultural, horticultural or domestic habitat; Constructed, industrial or other artificial habitats

Reproduction

Thought not to seed in Ireland or Britain (Booy et al.,2015). Has hybridised with the Japanese knotweed (Fallopia japonica) to produce the Railway-yard knotweed (Fallopia x conollyana) (Bailey, 2001), though that species is thought to be rare in Britain and not recorded to date in Ireland (Bailey , 2001; Booy et al., 2015)
