This low plant has star-like white flowers with 6 petals that rise from the center of a clump of long, narrow, grass-like leaves. It can be up to 6 in tall and is normally found in dry grasslands, meadows, mountain mahogany or open areas. Sand lilies generally bloom between March and June. After they have finished flowering, the entire above-ground parts of the plant wither away. The seed pods develop below ground near the roots of this plant so they often go unnoticed.
Sand lilies grow best in areas of full sun, such as prairies and meadows. The roots of this plant are edible and have been also been used to make a poultice for reduced swelling of wounds. This plant is the only species in the genus Leucocrinum.
