This looks a bit weedy but curious to know what it is before I uproot it.
One of the Willowherbs I think.
Weed with lots of seed.

Probably Rosebay Willowherb (so flowers are reddish/purple) but there is a white version too.
Zillions of fluffy seeds will float around and germinate all over the place if you allow it to seed
They have big fat roots which you need to remove completely, or they'll grow back.
It's a willowherb but I don't think it's rosebay. Looks more like Epilobium hirsutum, Great Willowherb
not that it makes much difference, above comments are still true.
