I thought that it looked suspiciously similar to Japanese Knotweed
(Fallopia japonica). It turns out that Polygonum cuspidatum is a synonym
of Fallopia japonica.

Red flowers suggests that it's a hybrid, rather than pure Japanese
Knotweed. (And the seed parent may also be a hybrid - between Japanese
and Giant Knotweeds.)

Defiantly an "I want one"
