Japanese Knotweeds
> These are all giant rhizomatous herbs originating from Asia, they are gynodioecious, with hermaphrodite and male-sterile (female) individuals. The hermaphrodites are self-incompatible and make poor female parents, so generally act as male plants (Bailey, 1989). New plants can originate vegetatively from very small fragments of rhizome, and in the introduced range this is the main means of spread.
> It was not actually recorded in its native Japan until long after its discovery in Europe. As a single male-sterile clone, any seed from F. japonica would inevitably be of hybrid origin; the subsequent introduction of hermaphrodite plants of F. sachalinenisis to Europe in the 1860s (Bailey and Conolly, 2000) allowed such hybrid seed to be formed.—Bailey, J. (2013). The Japanese knotweed invasion viewed as a vast unintentional hybridisation experiment
