Giant knotweed (Fallopia sachalinensis) is native to the Japanese island of Sakahlin. Similarly to Japanese knotweed (F. japonica) it was brought to Europe to be grown in botanical gardens, but then it escaped to the wild. Both species are similar in many respects: they multiply vegetatively by rhizomes and behave as invasives. However, giant knotweed is larger, growing over 4 m high and having leaves in range of 20-40 cm. The intermediate hybrid between Japanese Knotweed and Giant Knotweed called Fallopia x bohemica occurs in the UK and some other places in Europe. This is particularly worrying as it may be capable of producing viable seeds, which increase its invasive potential (IVM).
