Bibb
Small heads mature early. Superior, juicy-sweet flavor. Dark green leaves are crisp and sweet.

Butterhead
The medium-green leaves are unusually thick and crisp, so the head is sturdy and holds well. The large, well-packed heart has excellent butterhead quality.

Red Leaf
Relatively slow, but makes a heavy head of well-colored, frilly leaves. Popular in the East.

Romaine
Heavy, dense hearts. Dark green leaves are crisp and sweet.
