The chicory species includes endive (Cichorium endivia), Cichorium pumilum, and common chicory (Cichorium intybus). Common chicory includes chicory types such as radicchio, puntarelle, and Belgian endive.
There are two main varieties of cultivated endive:
- Curly endive, or frisée (var crispum). This type has narrow, green, curly outer leaves. It is sometimes called chicory in the United States and is called chicorée frisée in French. Further confusion results from the fact that frisée also refers to greens lightly wilted with oil.
- Escarole, or broad-leaved, endive (var latifolia) has broad, pale green leaves and is less bitter than the other varieties. Varieties or names include broad-leaved endive, Bavarian endive, Batavian endive, grumolo, scarola, and scarole. It is eaten like other greens, sauteed, chopped into soups and stews, or as part of a green salad.
