How to Grow
Planting Hymenocallis caroliniana bulbs should occur in the fall. Select a location that receives full sun to partial shade, ensuring the soil stays consistently moist. Plant the bulbs approximately 4 inches deep and space them 6 to 10 inches apart to give the clumps room to spread naturally.
Maintenance for the Spider lily is generally low, provided its specific hydration requirements are met. The most crucial factor is watering: soils must never be allowed to dry out. If you are growing this plant near the colder edge of its range (Zone 5), provide protected locations to ensure reliable winter survival.
After the blooms fade in the late summer, resist the urge to cut back the foliage. The leaves of Hymenocallis caroliniana remain green well into the dormant season, storing energy in the bulb for next year’s impressive display. Allow the foliage to naturally senesce before clearing it away in spring.
Landscape Uses
The cultural requirements of the Spider lily dictate its best landscape placements. It is ideally suited for locations requiring reliable moisture, such as bog gardens or along the edges of streams and ponds, where it can truly excel as a Water Plant. Where consistent moisture can be maintained, it also performs beautifully when integrated into a mixed border setting.
These striking white flowers, rising on sturdy scapes, look stunning when paired with marginal aquatic plants or moisture-loving woodland species. Since they are rare in the wild, successfully cultivating Hymenocallis caroliniana in your garden honors this unique native perennial. Plan your design around the need for consistent wet soil to ensure these striking bulbs thrive.

Noteworthy Characteristics
Hymenocallis caroliniana, commonly called spider lily, is a Missouri native bulbous perennial which occurs in swamps and moist woods in the Mississippi lowlands area in the far southeastern corner of the State. It looks like a spidery daffodil with extremely narrow perianth (petal-like) segments, featuring a basal clump of strap-shaped, amaryllis-like leaves growing directly from the bulb. In summer, scapes rise high above the foliage, topped by umbels of fragrant, white, spidery flowers, each measuring up to 6 inches across with a distinctive daffodil-like central cup.

Companion Planting for Wet Areas
When designing a water garden or rain garden featuring the Spider lily, consider pairing it with other moisture-loving perennials that share its preference for full sun to part shade. Good companions include Iris species, especially Louisiana Iris, which bloom around the same time and appreciate similar conditions. Caltha palustris (Marsh Marigold) can complement the early spring structure before the Hymenocallis caroliniana takes center stage. Also, look to native grasses that tolerate wet feet, such as some varieties of Carex, to provide textural contrast to the strap-like foliage.
Seasonal Care Calendar
Success with Hymenocallis caroliniana revolves around managing its moisture needs throughout the year. During the active growing and blooming season from late spring through summer, consistent vigilance over watering is critical—never allow the soil to become truly dry. In the fall, after the foliage begins to senesce, stop relying on heavy watering, though extreme dryness should still be avoided, especially in colder zones. In early spring, no fertilization is typically required; simply clear away any dead foliage from the previous year, ensuring you leave the bulb undisturbed to prepare for July and August flower production.
