The sand leek is a perennial plant with an egg-shaped bulb. The plant produces two to five unstalked leaves, the bases of which are sheath-like. Each leaf blade is linear, 7–20 mm wide,<ref name=Stace>Template:Cite book</ref> flat with a slight keel, an entire margin and parallel veins. The edges of the leaf and the central vein are rough to the touch. The flowering stem is cylindrical, growing to a height of Template:Convert and the upper half is leafless. The whole plant has an onion-like aroma. The inflorescence is a globular cluster surrounded by membranous bracts in bud which wither when the flowers open. Each individual flower is stalked and has a purple perianth Template:Convert long. There are six tepals, six stamens and a pistil formed from three fused carpels. Mixed with the flowers are a number of purple bulbils. The fruit is a capsule, but the seeds seldom set, and propagation usually takes place when the bulbils are knocked off and grow into new plants.<ref name=NatureGate>Template:Cite web</ref>


The natural habitat of A. scorodoprasum is damp broad-leaved woodland, forest margins, shores, hillside meadows and hedgerows. It was at one time used as a kitchen herb and can sometimes be found near old habitations.<ref name=NatureGate/><ref name=PFAF>Template:Cite web</ref>


A. scorodoprasum is edible but seldom cultivated, and has a shorter flower stalk and fewer and more inconsistently shaped cloves than Rocambole garlic. Sand leek also has a dark violet bulb wrapper.<ref>Growing Great Garlic, 2nd Edition, Filaree Productions, 1992, p. 7.</ref>

Elephant garlic (properly A. ampeloprasum var. ampeloprasum) is also sometimes incorrectly sold as A. scorodoprasum.Template:Citation needed
