That is Chevreulia acuminata, not tramp weed. I have been trying to find out what it is for a couple of years now. I still cant find info. on controling it or killing it.

This trampgrass is the curse of all curses for this land owner. It started off as small patches then turned into a major problem. Have sprayed with several different suggested weed killers but it just keeps coming back and spreading from yards to pastures. Now dealing with mature growth along with new growth. County agent is aware trampgrass is here.

Looks like a dandelion

Please resubmit with photos of this plant in its natural settings, base of the plant, more closeups of leaf stems , & ‘the single white stems’ before the seed heads reaching mature stage as the one above. Perhaps we might be able to get more clues to narrow down for you. Best wishes!

Thanks Walter, we started with your site, and thought it was not a match. Ours all have bare stems, no branching, and the only leaves are the ones on the ground in the mats of growth. Nothing stands except for the single white stems with a seed puff.
