Hymenocallis occidentalis is a plant species native to the southern United States . It is known along the Gulf Coast from South Carolina to Texas , and in the Mississippi Valley as far north as southern Illinois and Indiana .[3] It is also cultivated as an ornamental elsewhere because of its showy, sweet-smelling flowers.[1] Common names include woodland spider-lily, hammock spider-lily or northern spider-lily.[4]

Many of the other U.S. species of the genus grow in wetlands and along streambanks, but H. occidentalis can often be found in mesic forests.[1] Some of the Mexican species (e. g. H. clivorum and H. pimana) can similarly be found some distance from waterways.[5][6][7]

Hymenocallis occidentalis is a bulb-forming perennial herb bearing an umbel of 3-9 showy flowers, each white with a green center, opening one at a time. Leaves are lanceolate, up to 60 cm long and 6 cm wide at their widest points.[1][7][8][9][10]

The name Hymenocallis caroliniana has been frequently misapplied to this species but is properly a synonym of Pancratium maritimum.
