Species ca. 10 (1 in the flora).

Several species of Leucojum are cultivated for their flowers. Although other species such as L. autumnale Linnaeus (autumn snowflake) and L. vernum Linnaeus (spring snowflake) may persist in old gardens, only the commonly cultivated L. aestivum (summer snowflake) is known definitely to be naturalized in the flora. There are unconfirmed reports that L. vernum is naturalized in the panhandle area of Florida.

Leucojum is sometimes confused with Galanthus, a spring-flowering, Eurasian relative, but it differs in that Leucojum has perianth segments that are all equal in size, and hollow stems that are usually taller and bear 2–5 flowers. In the southern states, the common name snowdrop, which usually refers to Galanthus species, is applied to Leucojum.

Leaves and bulbs of Leucojum contain the alkaloids lycorine and galanthamine, and are poisonous.
