Cosmos atrosanguineus 'Chocamocha' syn. Cosmos atrosanguineus 'Thomocha'

Help me identify this plant. I first noticed it a couple of months ago and it’s getting quite big now. It doesn’t look like a weed but who knows 🤔 PlantID

Could it be a Michaelmas Daisy? 🤔

It looks like Gaura 🤷🏼‍♀️

I think it looks a bit like chocolate cosmos?

Chocolate Cosmos was my guess too Joan 😀 @joanboston

Thanks very much all. I think Joan and Sarah are right and I'm delighted as I thought I'd lost it during those last sharp frosts we had but this isn't where I thought I'd planted it. I really should remember to label plants when I move them 🙄😂 @jacaranda @wagsmomthompsonbtinternetcom @joanboston @sieveheadsarah

So Cosmos don't all have the same feathery foliage?🤔

No, this is a perennial one, it’s not anything like the annual ones. Click on the plant name and have a look. It’s a beauty Chris 🤎 @midnightgardener
