Allium membranaceum grows from an egg-shaped bulb up to 1.7 cm long which is sometimes associated with a cluster of smaller bulbs. The stem reaches a maximum height near 40 centimeters and there are two or three long, flat leaves about the same length. The inflorescence contains up to 35 flowers with white or pale pink tepals which become papery as they age. Anthers and pollen are yellow.[2][5][6]
