Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. The family, Solanaceae, has the common name of nightshade, which sounds like something to avoid like the plague, includes some of our favorite vegetables. Besides tomatoes, other members are peppers, eggplants, and potatoes, and still an important agricultural crop, tobacco. Flowers include Datura, brugmansia, petunias and nicotiana. One important gardening and farming practice is crop rotation.
