Allium scilloides produces bulbs along an underground rhizome, each bulb round to egg-shaped, up to 2 cm across. There are usually two thick flattened leaves that curl near the ends and are often nearly prostrate on the ground. Flowers are bell-shaped, about 7 mm across; tepals white, pink or purplish with green midribs; anthers purple; pollen white to gray. Flower buds are often dark red to dark pink before opening.[3][6][7][8][9]
