Any idea what this fast spreading plant is?

Hoping someone can help me ID this fast spreading green plant. It’s growing extremely quickly in my garden, infringing on other plants, and I’m keen to know if it’s a weed and/or something I should be looking to remove. Many thanks 😊

    Could be one of the Persicarias … some are absolutely lovely …

    I think it is Redshank, which is a weed but in the Persicaria family.

    That was my first thought @Busy-Lizzie …especially with the faint thumbprint on it … but there are some of the choice ones have that marking too … perhaps let it flower …?

    Yes, it may be OK. I said I think, not I'm certain though  :D

    Thanks all - this does look similar to your suggestions.  I’ll keep an eye on it and see if it develops colour like the Redshank. Does anyone know if it’s destructive to the other plants & I should cut it back? I trimmed it back earlier this year and it grew back very quickly. It’s a good border filler but I don’t want it to kill all other plants in its path or cause damage!

    It won't kill other plants but it will compete for moisture and nutrients and can overtake less vigorous but more attractive plants.  I'd get rid.

    I asked about this persicaria a few months back, as it was something in my new garden I'd not come across (I didn't post a photo, as had id'd it separately as redshank) and the common view was get rid of it, it will seed everywhere for ever...!


    I'm finding loads of seedlings of this still growing all over the place, despite having hoiked out everything I could see. It does come up nice and easily when you do need to pull it, though, so it's not on my hate list as much as the bindweed that has turned out to be my biggest problem weed here.

    Unless it’s a newly acquired or long neglected garden I’d be surprised if Redshank weed has become so well established in one growing season as in the OP’s picture.
