Heritage plants, sometimes known as heirlooms, are a type of plant found or grown in gardens more than 50 years ago. We keep them as heirlooms of an older time (hence the name) and encourage them to grow as they did in the wild or in earlier gardens. At one time, heirlooms were used as a source for food or even medicine along with the more familiar task of providing pleasant scents and sights. To have a garden of heritage plants is to watch history grow. Some of our plants are prehistoric, some from ancient Greece and Rome, some from the Middle Ages and all ones your grandmother may have grown. They are survivors.
