Lettuce (Lactuca sativa) is a cool-season vegetable that thrives in the lower temperatures of spring and fall. This is an important point as many people assume lettuce and many vegetables require full sun and high summer temperatures. This is not true. In many respects lettuce works best either side of main summer crops in the spring and fall when nothing much else is available in the garden. The summer heat causes most lettuce to bolt and go to flower producing bitter and tough leaves.
