Arugula (Eruca vesicaria sativa) is a leafy green herb of the mustard family. Known also as rocket, Italian cress, roquette, and rucola, it has elongated dark green leaves that are lobed like the leaves of an oak. In the ground, the plant resembles a loose lettuce with long, slender leaves.
The fact is, with its appearance, texture and taste nearly indistinguishable, Butter, Boston and Bibb lettuce is ostensibly the same variety known under the category moniker: Butterhead. Bibb, however, is a slightly smaller version of the variety and is the first of this cultivar to be grown in the U.S.
Frisee is a type of chicory that has exploded onto gourmet plates. The exotic plant resembles a lettuce gone horribly awry, with a pale green explosion of frizzy leaves that adds a frisky note to green salads. Some consumers are radically opposed to frisee, while others adore the bitter and sometimes woody green.
Napa Cabbage - Also called Chinese cabbage, this oblong-shaped cabbage has thick, crisp stems and frilly yellow-green leaves. We think its flavor is sweeter and softer than green cabbage, and we really love eating it raw in salads and using it in the filling for dumplings.
