Many of the plants we view as vegetables are actually fruits: tomatoes, cucumbers, zucchinis are the fleshy containers of seeds and are technically fruits. Nonetheless, they may all be included in a vegetable garden. Tomatoes must be started indoors under lights, so it is often easiest to buy young plants from a garden center. Cucumber and zucchinis are easy from seed but wait until after the last frost day before planting. Get your seeds from a garden center or online: look for organic varieties.
