Several onions are arranged horizontally one behind the other. The onion's skins are thin. The stem is angular. The plant has 4-9 linear leaves that are 0.1-0.6 inches wide and 4-30 inches long. They are all basal, almost completely flat and slightly rounded on the underside but not keeled. The spathe is two to three parts, 5-8 millimeters long and shorter than the 8-20 millimeter long flower stalks. The umbel made of numerous flowers has a diameter of 2-5 centimeters and is hemispherical. The inflorescence is bowl-shaped, purple, the outer tepals are lanceolate or narrowly ovate, the inner ones are longer than the outer ones. The stamens protrude beyond the perigone, the filaments are 4-6.5 millimeters long, the outer ones are 0.5 millimeters wide at the base, the inner 1 millimeter. The ovary is deeply three-part. The fruit capsule is 4 mm long. The chromosome number is 14, 24 or 32 + 0-4B.

Occurrence
The range of the mountain leek is limited to Europe. In Central Europe it thrives in sunny ledges and rock lawns on warm, base-rich, shallow, mild, humus-rich stone soils. It is a character species of the order Sedo-Scleranthetalia, but also occurs in societies of the Xerobromion or Koelerio-Phleion associations. In the Alps, it rises to around 2,340 meters above sea level. In the Allgäu Alps, it rises up to 2040 meters above sea level on the beggar's back near Spielmannsau in Bavaria.
