The Q&A Archives: The Mystery Of Fallopia....

Question: The mystery is why varigated fallopia (which I bought from a local nursery with your tag on it several years ago) NOT listed in the Sunset Western Garden Book? Indeed, yesterday, I checked three or four other encyclopedic type garden books in a book store and could not find it. I was beginning to doubt that I had the name correct! Why would it not be listed anywhere? AND why do my leaf edges turn brown and crisp? From your description on this website, it cannot be too much sun, as I is not even in full sun. It is, however, in a pot, so maybe the roots are unhappy. I would appreciate this information. Thanks! Jeannie

Answer: Fallopia japonica 'Variegata' is a member of the Polygonaceae family. Its common name is Variegated Japanese Knotweed. This plant has white and green mottled leaves; white flowers; blooms in late summer; and can be invasive.
Because this plant spreads by underground rhizomes, being contained in a pot will keep it from escaping cultivation, but may also hinder its natural growth habit. This stress can affect the growth and appearance of the foliage. If it were mine, I'd keep it in a pot to keep its growth under control, but I'd move it up to a slightly larger pot to keep the root system happy. Best wishes with your Fallopia
