Butterhead types have smaller, softer heads of loosely folded leaves. Several cultivars grow well in Georgia gardens. Leaf lettuce doesn't form a head. The leaf form and color varies widely. Some cultivars are frilled and crinkled and others deeply lobed.
Color ranges from light green to red and bronze.
Leaf lettuce matures quickly and is the easiest to grow. Romaine or cos lettuces form upright, cylindrical heads of tightly folded leaves. The plants may grow to 10 inches. The outer leaves are medium green with greenish white inner leaves. Romaine is the sweetest of the four types.
