Kale

Kale is a leafy green vegetable that belongs to the Brassica family, a group of vegetables including cabbage, collards and Brussels sprouts that have gained recent widespread attention due to their health-promoting, sulfur-containing phytonutrients. There are several varieties of kale known commonly as curly kale, ornamental kale and dinosaur kale, all of which differ in taste, texture and appearance. The scientific name for kale is Brassica oleracea.

Curly kale has ruffled leaves and a fibrous stalk and is usually deep green in color. It has a lively pungent flavor with delicious bitter peppery qualities.

Ornamental kale is a more recently cultivated species that is oftentimes referred to as salad savoy. Its leaves may either be green, white or purple and its stalks coalesce to form a loosely knit head. Ornamental kale has a more mellow flavor and tender texture.

Dinosaur kale is the common name for the kale variety known as Lacinato. It features dark blue-green leaves that have an embossed texture. It has a slightly sweeter and more delicate taste than curly kale.

History

Like broccoli, cauliflower and collards, kale is a descendent of the wild cabbage, a plant thought to have originated in Asia Minor and to have been brought to Europe around 600 B.C. by groups of Celtic wanderers. Curly kale played an important role in early European foodways, having been a significant crop during ancient Roman times and a popular vegetable eaten by peasants in the Middle Ages. English settlers brought kale to the United States in the 17th century.

Both ornamental and dinosaur kale are much more recent varieties. Dinosaur kale was discovered in Italy in the late 19th century. Ornamental kale, originally a decorative garden plant, was first cultivated commercially as in the 1980s in California. Ornamental kale is now better known by the name salad savoy.
