What is this plant? – Reddit Post

Hi everyone,

First time posting here as I started my gardening adventure. I’m trying to create a wildflower meadow. I prepped the soil, sowed my wildflower mix 2 weeks ago and now I’m seeing these plants pop-up and in some parts they are quite overwhelming. I don’t know if I should remove them or not. They vaguely resemble cosmos, but the leaves don’t really look the same so I’m guessing it could be some weeds? I tried looking it up but didn’t find it online. I was hoping communities like these had some more experienced people that could help me out to determine what these plants could be.

Thanks a lot!
