Last summer I expanded on my herb garden, moving all my rosemary, thyme, basil and sage from pots into a sunny plot, and this year I'll probably add even more - parsley, lots of chives and lots more russian sage. I had miserable luck growing several varieties of mesclun and spring mix lettuce, so I'm going to stick to herbs in the culinary part of things.
