My daughter Sage and I harvested our first crop already this Spring, though it felt like cheating. I planted some lettuce and pansies in the ground the other day (purchased at Skillins rather than growing them myself), and we nibbled on some the other day. Sage loved being able to eat the flowers. I also found some arugula that over-wintered underneath a cold frame in my back yard. Most of it was still tender and green, so we both ate some. Eliot Coleman is right: you can have a four-season harvest in Maine.
I'm already planning for my Fall bulb planting. I have such dreams of splendor over the winter, only to find what emerges to be less than half of what was in my imagination.
