A terribly invasive plant - I must have helped shift tonnes of it over the years - to little avail.
A great survivor, too: uprooted and laid on the ground it will re-root.
Tell me about it Roger I saw swathes of it growing alongside the River Exe some years back and wonder if it is still there.
Thanks for the confirmation.
