Last winter, I wintersowed 3 different Carex varieties, muskingumensis, grayi and seeds from a volunteer that appeared in my garden. Of the 3, only grayi has double dormancy. It required warm/cold/warm moist strat. The other 2 needed only cold/warm. All 3 germinated, 100% for the unknown variety, 88% for muskingumensis and 50% for grayi.

thanks a lot so much!!donn.
