I’m not a homespun Martha Stewart by a long stretch, but I do exult in minor gardening triumphs like being able to pick food from my garden in December. I learned in London that some greens–like arugula–can survive freezing. This year I planted mesclun (a seed mix) and mustard greens in late August. As you can see, even after a couple of snowfalls, the mustard looks beautiful (and has a sweeter taste, I think). I pick it frozen and after it thaws in the house it’s crisp enough for a salad, though it’s also good stirfried with a little garlic.
