Types of Lettuce Greens
Butterhead lettuce: This type includes Boston and Bibb lettuces, which are characterized by a loose head and grass-green leaves. Both have a soft “buttery” texture and a sweet, mild flavor. A head of Boston lettuce resembles a flowering rose. Bibb lettuce—also called limestone—forms a smaller, cup-shaped head.
