Definition
The garden leek (Allium porrum L.) is a biennial plant belonging to the family of Liliaceae and coming from the Mediterranean regions. It is characterized by long lanceolate leaves. Both the lower part of the plant, called "bulb" and consisting of overlapping and sheathed leaves, whitening during the vegetative stage, and the proper leaves, that are flat, tender, and fleshy, can be eaten in various ways or can be used as a dressing for their aromatic taste. The leek has also diuretic and emollient features, and is used in popular medicine to prepare teas and syrups.
Besides the renowned sweet peppers, horticulture in the area of Carmagnola (Turin) boasts a local selection of this vegetable, known as "Porro Lungo Dolce di Carmagnola" (Carmagnola Long Sweet Garden Leek) and obtained about forty years ago thanks to a careful and efficient selection that has found in the area of Carmagnola an ideal habitat (light soils, alluvial, on the right bank of the river Po).
Carmagnola Long Sweet Garden Leek is very tender and has a marked sweet taste. Moreover, it is easy to digest.
