Hi Can anyone help identify what this plant is?

Looks like a Mexican sunflower (Tithonia rotundifolia).

My initial thought was a Geum

I agree Andy, it looks like my Geum.

I'd say geum too

I would even go as far as to say Geum Fireball.

Let it flower. That's the natural habit. Untidy but magnificent. Tidy it up when it's done

Not a lover of geums but the colour and habbit of that is lovely

Hi

Thanks, yes I would say Geum, it suddenly exploded a few weeks ago form nowhere. I'll leave it another week and cut it back. Thanks again

I love Geums . Yes they sway and flop and are ''informal''.
But that's their beauty. Perhaps moving them to a different part of your garden would be better- Dare I say ''Right plant - wrong planting area '' Lovely display though

Thanks, do you know when is the right time to move them?

John
