As a comment about Perfumed spiderlily (Hymenocallis latifolia)
The Perfumed Spider Lily is a native here in the central and southern part of Florida. H. latifolia grows 4 feet in height, with thick narrow 18 to 36 inch long leaves that form directly from the base of the plant, growing in an upright and arching fashion. The large tubular white flowers consist of 6 long narrow petals that abruptly bend downwards below the funnel shape, dangling like spider legs, hence the common name Spider Lily. Blooming in spring, summer and fall the flowers appear in groups on long fleshy flower stalks. Habitats for the Perfumed Spider Lily consist of coastal sites, mangrove swamps and dune margins. Hymenocallis latifolia is extremely salt tolerant, making it an ideal plant for coastal gardens.
