Genus:Hymenocallis

Species:crassifolia

Family:Amaryllidaceae

The Coastal Spiderlily is indigenous to the southern coastal regions of North Carolina and extends down to Florida. This herbaceous perennial bulb thrives in wet soil, often found in areas with up to six inches of standing water, such as tidal marshes, the edges of tidal guts, and the banks of backwater rivers. Its leaves are strap-like and nearly upright, while its fragrant flowers bloom in clusters during the spring.

This plant thrives in consistently moist conditions and should not be allowed to dry out between waterings. It is well-suited for use in water gardens, bogs, or alongside ponds.
