Chives, scientific name Allium schoenoprasum, are an edible species of the genus Allium. Their close relatives include the garlic, shallot, leek, scallion, and Chinese onion.
A perennial plant, it is widespread in nature across much of Europe, Asia, and North America.
A. schoenoprasum is the only species of Allium native to both the New and the Old Worlds.
Chives are a commonly used herb and can be found in grocery stores or grown in home gardens. In culinary use, the scapes and the unopened, immature flower buds are diced and used as an ingredient for fish, potatoes, soups, and other dishes. The edible flowers can be used in salads. Chives have insect-repelling properties that can be used in gardens to control pests.
The plant provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative.
Chives are grown for their scapes and leaves, which are used for culinary purposes as a flavoring herb, and provide a somewhat milder flavor than those of other Allium species.
Chives have a wide variety of culinary uses, such as in traditional dishes in France, Sweden, and elsewhere. In his 1806 book Attempt at a Flora (Försök til en flora), Retzius describes how chives are used with pancakes, soups, fish, and sandwiches. They are also an ingredient of the gräddfil sauce with the traditional herring dish served at Swedish midsummer celebrations. The flowers may also be used to garnish dishes. In Poland and Germany, chives are served with quark cheese. Chives are one of the fines herbes of French cuisine, the others being tarragon, chervil and parsley. Chives can be found fresh at most markets year-round, making them readily available; they can also be dry-frozen without much impairment to the taste, giving home growers the opportunity to store large quantities harvested from their own gardens.
Uses in plant cultivation
Retzius also describes how farmers would plant chives between the rocks making up the borders of their flowerbeds, to keep the plants free from pests (such as Japanese beetles). The growing plant repels unwanted insect life, and the juice of the leaves can be used for the same purpose, as well as fighting fungal infections, mildew, and scab.
The medicinal properties of chives are similar to those of garlic, but weaker; the faint effects in comparison with garlic are probably the main reason for their limited use as a medicinal herb. They also have mild stimulant, diuretic, and antiseptic properties. As chives are usually served in small amounts and never as the main dish, negative effects are rarely encountered, although digestive problems may occur following overconsumption.
Chives are also rich in vitamins A and C, contain organosulfur compounds, and are rich in calcium and iron.
