Sage, or Salvia, a genus of plants native to tropical and temperate regions. The genus is made up of about 700 species, most of which are herbs. Plants of this genus can grow to a height of five feet (1.5 m). Their stems are square. Sage plants produce black, round seeds and bear flowers that can be purple, scarlet, blue, white, or pale yellow, depending on the species. Some species of sage, such as silver sage and scarlet sage, are cultivated for decoration, and some, such as garden sage, are grown for the seasoning obtained from their dried leaves. Others, such as clary, are grown for sage oil, which is used in making perfume.
Garden sage (common sage), native to Europe but also grown in North America, is a perennial shrub. It usually reaches a height of two feet (60 cm). The gray-green, aromatic leaves are used as a seasoning. In some parts of the world the leaves are also used for home medicinal remedies.
