Description

Coastal spiderlily, in the amaryllis family (Amaryllidaceae), is native to the southern coastal counties of NC and south to Florida. It is a herbaceous perennial bulb that grows in moist soil with up to 6 inches of standing water in tidal marshes, margins of tidal guts and banks of backwater rivers.

Coastal spiderlily grows 2 to 4 feet tall and requires consistently moist soil and 4 to 6 hours of sun daily for best blooms. Do not let the soil dry out between waterings. Propagation is by division or seed.

The large showy, fragrant spiderlily-like flowers open at dusk and stay open until morning, attracting moths. The strap-like leaves grow nearly upright

Use coastal spiderlily in a water garden, along a pond, stream or bog. Use in a nighttime garden or in a container with no drainage holes.

Insects, Diseases, and Other Plant Problems:   No significant problems. Watch for snails and slugs, mealybugs, thirps and spidermites. Potential diseases are root and crown rot and fungal leaf spot. The caterpillers of some moths and butterflies will feed on the leaves.
