how do I tell whether my triffid is russian vine or japanese knotweed?
Just moved house and have a shed load of triffid up and through a small tree. Can't get to the base to see the stems. Leaves are max 7cm long, trailing shoots red, clusters of flowers white. I can't distinguish from the web descriptions of each plant. Any tips? Will one or the other fruit, for example?
