I just moved into my home in oct. now in may I have a very dark green grass looking plant coming up in the grass.6 or 7 of them like a poof of grass but very green. anyone know what it could be?
It could be anything. those little onion-y like clumps from the onion family, spring beauties etc. Without a picture it is virtually impossible to help or even throw you guesses.
Agreed, but a few things do come readily to mind. Tradescantia (spiderwort,) annual grass like Poa annua, crabgrass. Maybe the search results here could help if it's not one of these: https://www.google.com/#q=grass+weeds+of+michigan
