Garlic, Storage : Cool, Dry Place

Allium sativum, commonly known as garlic, is a species in the onion genus, Allium. Its close relatives include the onion, shallot, leek, chive, and rakkyo. Dating back over 6,000 years, garlic is native to central Asia, and has long been a staple in the Mediterranean region, as well as a frequent seasoning in Asia, Africa, and Europe. It was known to Ancient Egyptians, and has been used throughout its history for both culinary and medicinal purposes.

The ancestry of cultivated garlic is not definitively established. According to Zohary and Hopf, “A difficulty in the identification of its wild progenitor is the sterility of the cultivars”, though it is thought to be descendent from the species Allium longicuspis, which grows wild in central and southwestern Asia. Allium sativum grows in the wild in areas where it has become naturalised. The “wild garlic”, “crow garlic”, and “field garlic” of Britain are members of the species Allium ursinum, Allium vineale, and Allium oleraceum, respectively. In North America, Allium vineale (known as “wild garlic” or “crow garlic”) and Allium canadense, known as “meadow garlic” or “wild garlic” and “wild onion”, are common weeds in fields. One of the best-known “garlics”, the so-called elephant garlic, is actually a wild leek (Allium ampeloprasum), and not a true garlic. Single clove garlic (also called pearl or solo garlic) originated in the Yunnan province of China.

Varieties
While botanists classify garlic under the umbrella of the species, Allium sativum, there are also two main subspecies. Ophioscorodon, or hard necked garlic, includes porcelain garlics, rocambole garlic, and purple stripe garlics. Sativum, or soft necked garlic, includes artichoke garlic, silverskin garlic, and creole garlic.

Bulb garlic is available in many forms, including fresh, frozen, dried, fermented (black garlic) and shelf stable products (in tubes or jars). In addition, see Culinary uses for other edible parts of the garlic plant.
