Chocolate Cosmos Plant

Last year I bought a chocolate cosmos plant and when it died back I didn't do anything with the bulb (I'm assuming it was a bulb from what I read).

Anyway this year saw some green shoots reappearing so left it to do its thing

I've since become sceptical of what is growing so decided to lift it out of pot as it basically looks like a weed.

The roots look really thick so am confused. Can someone tell me whether I have been tending to a potted weed please....

 

Haven't had one for years, but Cosmos atrosanguineus has tuberous roots, so that's perfectly fine! Trouble is I can't quite remember what the foliage looked like at such an early stage...

Thank you for your response nick. It doesn't look like anything I imagined the plant did last year.

As you say tho those tuberous roots can't be from a self seeding weed surely..... it looked more like the plant when first sprouting but as its bushed out and not really grown in height I am doubting myself

 

The leaves look to me as if they are emerging from the tubers. The mature leaves should be pinnate but the young leaves of a plant are often unlike the mature ones.
I'd plant it back and let it grow until you are sure what the mature leaves look like.

 

Thank you I will do this.
