    Hello I need I.D on the weed in pics shown. It looks similar to Butterfly Plant but it isn't. I has white knuckles at the leaf nodes. Each stem is hard to pull out with long deep tap roots (or long root connected to underground roots). No idea if it flowers as I pull them out when they are still small. They can grow a foot tall in a week

    Any advice as it's beginning to take over all my beds

    Looks a bit like Japanese knotweed. Someone more knowledgeable will be along soon.

    If I'm right, best advice is - move house

      I think it a knotweed of some sort but not Japanese.

        I can say with 90% confidence that it isn't Japanese Knotweed, possibly even not being Knotweed in any form. However I could be wrong

          The leaves look wrong for JK, not something I regonise though

            Its hard to see the detail in your photos as they are so small.
            I've tried to enlarge them but it doesn't help.

            If you let one flower , even if its cut and in a vase, we'd have a better idea.

            Why do you think its isn't a knotweed?

              I am going with Himalayan Balsam

                I've looked at Himilayan Balsam and I decided it's not that on the basis that follows:-
                A) The stems on the Himilayan Balsam plants are quite dark in colour close to red, whereas mine are lime green. Although the idea of said stems eventually turning darker is a possibility.
                B) At every leaf node there is a white knuckle which the Balsam doesn't have any knuckles
                C) Each leaf node only has 1 leaf. No more than that, Balsam sometimes has up to 5 leaves per node

                Having said all that it is the closest I've found so far. I am happy to try and get one of those to flower but I can't be sure how long that is going to take. Also, when I pull one out the root is very long at least a foot long and it's snapped off at the end. So must be a deep root system with the behaviour trait of stinging nettles

                  Another possibility is Persicaria Amphibia. So looks the same so I guess we are back into the Knotweed family. What sort of damage limitation am I looking at? As stated previously it's pooping up everywhere. In GH, lawn, beds etc.

                      It's not Himalayan Balsam, i have that on my plot and it has very shallow roots and a thick but hollow fleshy stem... and its very easy to pull out.

                        This is driving me mad, I have a real deja vu looking at it but can't place it. Definitely not JK or HB, I promise.

                        It's not a relative of jerusalem artichoke is it?

                          Is it a Polygonum bistorta or part of that family?

                            It's not that. Wrong leaf shape. I guess the only way to really know is to let it flower
