Plants require sunlight for their growth and in fact, most of them only grow if they are provided with at least six hours of sunlight in their day for nourishment. While no vegetables can actually grow in complete darkness, some of them can do remarkably well when grown in the shade. This is contrary to the expectations of many people who tend to think that a vegetable garden must be baked in complete sunlight all day long. Actually, this might not be very far from the truth as some vegetables like peppers, squash and tomatoes require sunlight in plenty to grow.
