Also called 'Sucrine' or 'Sugar Cos', 'Little Gem' is an English heirloom that is a small variety of romaine, but has the succulent sweetness of a butterhead. The glossy-leafed heads are a petite, 6" tall and 4" wide—the perfect size for an individual dinner salad. The tender, blanched heart is ideal for any recipe that calls for "hearts of romaine."
