A half-dozen nights of single-digit cold should have done in the last of the greens, but they look discouraged, not dead. My cold frames are nothing but a box with an old window set on top, but that's been enough to protect the hardier mustards, chards and greens.
Granted, they are not exactly luxuriating under our stingy winter sunlight, and they only exist because I haven't been harvesting them. But still they are edible - and in their small doses they pack infinitely more flavor and vitality than the supermarket greens that one can buy.
I'm definitely motivated to make the autumn garden a priority in the future and see if I can generate more of a winter harvest.
The window-lids don't just allow in winter sunlight and protect against the cold.
They also give some protection from four-legged marauders.
Into a teapot I crushed mint
that I had picked and dried for just such January days,
and drizzled in the honey from the backyard hives,
and settled down with a hot and steaming tea that tasted like August.
