Mache lettuce has delicate, elongated leaves that are bright green, thin, pliable, and smooth with a spatulate shape and grow in a loose, rosette pattern of 6-8 leaves. The ends of the leaves are typically rounded with semi-toothed edges, and prominent veins span across the surface. The stems are also green, razor thin, and tender. Mache lettuce is soft, velvety, and crisp with a mild, herbal, and nutty flavor.
