There's a very short grass seed mix called "no mow" at High Country Gardens. I'm thinking of using it. FIRST, I shall cover the tall grass with newspaper and soil/compost, then sow groundcover, possibly that grass mix. Thyme is wonderful to walk on! And I have a cinquefoil I brought home October 2010 in a 3" pot that's almost covered my (small) front yard already. It's evergreen! Wish I could remember its name. It's very low and has yellow flowers that come early and stay long. THAT's going into the backyard, too.
