Allium porrum

Taxonomy

The leek, scientifically known as Allium porrum, is a vegetable and a cultivar of Allium ampeloprasum, which is also the broadleaf wild leek. It is often mistakenly referred to as a stem or stalk, but the edible part of the plant is actually a bundle of leaf sheaths. The leek belongs to the same genus as other popular vegetables like onion, garlic, shallot, scallion, chives, and Chinese onion. Additionally, there are three closely related vegetables, namely elephant garlic, kurrat, and Persian leek or tareh, which are also cultivars of A. ampeloprasum but differ in their culinary uses. The leek is a hardy perennial that is typically grown as an annual vegetable. It has thick, upright blue-green leaves and produces mid-length leeks with an average diameter of 4cm and 10cm of blanched stem. The harvesting time for leeks is usually from January onwards, depending on the sowing time. As a herbaceous biennial, the common leek is primarily cultivated for its edible leaves and roots. Its long leaves are flat and opposite, ranging in color from dark green to yellowish green. The base of the leaves forms a pseudo-stalk, and the buried white portion of the leek is highly valued for its culinary purposes. After a full year of growth, the leek produces greenish-white flowers in umbel groups atop straight floral stems. The European Catalogue of species and varieties lists nearly 190 different varieties of leeks.
