Greens for Early Winter

I've got a small planting of mache growing in one of the garden beds. I started this in early September, and hope it will get of sufficient size before winter really sets in so I can have some greens this December and maybe January.

This is something along the lines of Eliot Coleman's approach, using row cover, probably two layers, inside a cold frame/box. Coleman grows lots of winter greens in cold greenhouses, with glazing up top and planted rows covered with Reemay below. The folks at Johnny's Selected Seeds tell me this type of green stops growing when the daylight is less than ten hours, not when it gets cold. Mache and other greens are quite cold-hardy; with a little protection they can easily over-winter.
