Baby teasel plants form rosettes, and will be prominent right now.
I've actually spent most of this morning transplanting a lot of them. They can come up very closely packed together, so they really need to be thinned out, and transplanted elsewhere, if you have the space. They are quite easy to get up. They have tap roots (a bit like a small carrot), so you need to be a bit careful of that when digging them up.
