Sorry - no idea, but I’m bumping the thread so hopefully someone will be able to help you.

No idea either, I'm afraid. I did a Google search on your photo and came up with a couple of possibilities. I presume you did the same, but just in case, these two related plants looked like the most likely suspects.

You might need to wait for flowers to be sure. Both look to be very tall plants. Is that what you were expecting?

Here's my guess - but it is only a guess: https://www.bethchatto.co.uk/a-z/e-h...um-herbaceous/

My app says Eutrochium too.
I recommend the app "PlantNet". It's helped me out many times.

Plantnet says 'Not a plant' when I try!
