observing rosettes

I torture myself by observing and photographing rosettes (in a local park) which are often dug up or mown down before I get to see them identified. I still hope I can see them to flowering one day. (Don't let anyone see me photograph them or take an interest - sure fire way for the weedkiller / mower to come out)

this might be Crepis vesicaria?
