Now is the time to enjoy fresh local lettuce varieties. While tender greens like arugula and mache usually bring to mind hot summer days, they are able to weather the first frosts of the season. Soon the salad greens available will only be those grown in hot houses or shipped to the New York area from warmer climates. While this year’s wet weather brought late blight for tomato crops, lettuce faired well, particularly since many varieties require continual replanting.
