ampeloprasum

Ampeloprasum is the specific epithet most commonly encountered in the binomial name Allium ampeloprasum, a species in the genus Allium of the onion family (Amaryllidaceae, subfamily Allioideae; historically placed in Alliaceae). The epithet is used in botanical taxonomy to refer to this species, which includes several cultivated forms such as leek and elephant garlic.

Allium ampeloprasum is a bulbous perennial native to parts of Europe and western Asia. In cultivation, it is valued for both its leaves and, in some forms, its bulbs. The most familiar cultivated form is the leek (Allium ampeloprasum var. porrum), grown for the elongated, hollow leaf bases. Elephant garlic is another widely grown form, typically described as Allium ampeloprasum var. ampeloprasum, and it produces a large bulb with a milder flavor than true garlic.

Cultivation and growing conditions favor temperate climates with well-drained soil and ample sun. Propagation is possible by seed, by division, or by transplanting established plants for leeks. For leek production, soil is often mounded to blanch the stems and produce the characteristic pale, tender bases.

Uses and flavor: leaves are used as a vegetable, and in some cultivated forms the bulbs are also edible. Leeks are common in European cuisines and appear in soups, stews, and sautés. Elephant garlic is used similarly to garlic but offers a milder taste. The species and its varieties are widely grown in temperate regions and have a long history of culinary and culinary-adjacent use.
