Arugula is an annual that grows 8 to 24 inches high. It has dull- or shinygreen, deeply cut, compound leaves that are edible and have a distinctive spicy, pungent flavor resembling horseradish.
The vegetable was formerly called roquette (the French word for rocket), but the term “arugula” is now becoming more common.
The arugula can be divided into smoothedged or serrated-leafed varieties. Some arugula varieties are wild, although most are cultivated. The flavor varies depending on variety.
Origin & Botanical facts
Arugula belongs to the Cruciferae family and is a close relative of the mustard. Ancient Egyptians and Romans considered arugula leaves in salads to be an aphrodisiac. It is a minor crop in the southeastern United States, grown to a limited extent commercially and in home vegetable gardens.
Seeds often are listed in seed catalogs as “roquette” under the category of herbs.
A cool season vegetable best grown in Florida during the fall, winter, and spring, it matures from seed in 2 to 3 months. Periods of very warm temperatures cause it to bolt (go to seed) rather quickly. Few pests attack the arugula.
Uses
The freshest, crispest leaves free of brown spots should be chosen. Arugula should be used as soon as possible after purchasing. If necessary, after removing any wilted leaves, the remaining unwashed leaves can be refrigerated for no more than 2 days in a plastic bag.
The zesty leaves can be used raw in salads by themselves or tossed with other greens. Arugula also can be added to soups or lightly cooked and served as a side dish. The arugula is widely consumed in the Middle East as a garnish on meats and sandwiches. Tiny arugula blossoms also can be added to salads.
Nutrient composition
Arugula provides some vitamin A.
Asparagus
Asparagus is a member of the lily family and is related to onions, leeks, and garlic. It is cultivated for its edible young shoots, which are long and unbranched with compact, pointed tips made of tiny leaves.
Varieties
Two basic varieties of asparagus, white and green, are cultivated. The green variety is the only one grown on a commercial scale in the United States, whereas the white is preferred in Europe.
White asparagus is produced by banking soil against the plant to keep out sunlight, which otherwise would turn the stalks green. Also available, although not common, is a violet variety, with pinkish purple shoots and tips.
Origin & botanical facts
Asparagus was first cultivated in Greece about 2,500 years ago. In fact, the name asparagus is Greek for “stalk” or “shoot.” The ancient Greeks believed that asparagus had medicinal qualities and could cure toothaches and bee stings.
The cultivation of asparagus was adopted by the Romans, who carried it throughout Europe and Great Britain. From there, its popularity spread to the rest of the world. Traditionally, asparagus was a Northern Hemisphere crop, but today it is cultivated worldwide. The United States is the world’s largest supplier of asparagus, with most cultivation concentrated in California.
The asparagus plant is a perennial but requires three seasons to mature. In its first season, a crown forms with 6 inches of root. In its second season, the crown develops into a fern.
Asparagus can be harvested in its third season, but the plant does not reach its prime until 6 to 8 years of age. At peak age, an asparagus field can yield up to 2 tons per acre. Because its growing season is short and it must be harvested by hand, asparagus can be expensive.
Asparagus appears in American markets as early as February, when the first California crops are harvested, but the peak season in the West is from late April to late May and, elsewhere in the United States, from May through July.
Throughout the rest of the year, fresh asparagus may be available from Mexico and South America.
Uses
Asparagus stalks of similar width with tightly closed tips should be selected. Young asparagus is thinner and generally more tender. Fresh asparagus should be stored in the refrigerator with the cut ends immersed in water and should be used within a day or two.
Fresh asparagus is best steamed or microwaved until just crisp-tender. Steaming should be done quickly, with the spears in an upright position to heat the stalks evenly. The spears also can be roasted briefly in the oven with a little olive oil.
Cooked asparagus is best served immediately and simply, without rich sauces. Asparagus spears also can be cut into diagonal pieces and stir-fried. Asparagus is also available canned or frozen. Frozen spears are closer to fresh spears in flavor and nutrition. The canned variety is less nutritious.
Nutrient composition
Asparagus is a good source of vitamin C and is an excellent source of folate. It also contains glutathione, an antioxidant that promotes health.

all the lettuces and has the strongest flavor, though it is still mild. Great by itself, it is also good mixed with the more delicate salad greens as it adds a firm, extra crunchytexture and sturdiness.
