Sun-Maid's California Pitted Prunes are derived from La Petite d'Agen plums native to France. California's long, warm growing season produces fruit with ideal sweet flavor. Inside your Sun-Maid package you will find the right size prune for each member of your family--the way Mother Nature intended--quality, taste, convenience and real fruit goodness. Health experts agree adding more fruit to your diet will optimize your health. Add prunes to cereals, salads or snack from the package. Just a quarter cup (1.5 oz.) of Sun-Maid Prunes provides a full serving of fruit.
