The stout, angled flowering stalk usually remains shorter than the leaves and carries six to twelve fragrant flowers. Each has a long white tube, narrow segments that spread or curl backward, and a central cup; the fruit is a nearly spherical capsule. Royal Botanic Gardens Sydney, PlantNET: Hymenocallis caribaea
