What plant/weed is this?

[Redlarge]

I dont remember planting this. What is it please?
Should i chuck it?

Sorry here it is

Looks like peppermint

Thats what AI said but i honestly have never planted peppermint. Unless a random person put it in my garden ha ha. 😅 this is confusing me so much.

Not peppermint. Red stem, leaves too smooth and edges wrong.

Rosebay willowherb, I think.

It's a weed, it's a really prolific one. IDK what it's called but it grows really tall if you leave it. The best thing you can do is pull it out (it has really shallow roots and comes out easily) before it seeds with these white wispy seeds it eventually gets. It's taken over every garden I've ever had.

It doesnt smell of mint or anything at all tbh

Ergh i will do. In the bin it goes.
Thank you x

Certainly a willowherb. The leaves are opposite not spirally arranged, so an Epilobium rather than Chamaenerion (rosebay). Possibly broad leaved willowherb.
