Lettuce Gem, also known as Baby Gem, is a tightly packed head with an elongated, vase-like appearance. The broad, smooth, meaty, and wavy leaves have serrated edges and start out with a light green base before changing to a dark burgundy-maroon near the top of the leaves. Closer to the center, the leaves are ribbed, juicy, and crunchy, while the outer leaves are crisp with a melting aspect.
