Did I plant this?

Not a great photo. I'll try to get a better one with my phone, if necessary - when I find it!
It looks like it might be shrubby. It's near a gaura runner but I don't think it's related.


Edit.
I've cropped d it so you can see the one in asking about.u

 

A better photo would be great, @BB3, just to pin point if you are asking about the Japanese Knotweed on the left or perhaps about the sprouting Giant Hogweed just behind the Deadly Nightshade?

 

My favourite plants.
I'd better look for my phone and maybe do some more weeding

 

@Selleri . Had a closer look while I was preparing it for the photo. Dead daisylike flowers. Pretty sure it's erigeron K but thanks anyway for your useful advice. And I found my phone.

 

Dead, daisylike flowers? That’s Plantus neglectus @BB3 . It does sound and look like Erigeron, mine are all still green with faded flowers.

 

Definitely @Plantminded . It was hiding under something giganticus with big leaves and cream flowers.
