How to plant Hymenocallis bulbs

Depth, spacing & care (Spring)

Hymenocallis, often called “Spider Lily” or “Peruvian Daffodil,” is a bulbous beauty that brings delicate drama to late spring and summer gardens. Its striking, star-shaped flowers are typically broad, white plates with long filaments or “spider legs” that radiate around a central cup, evoking an ethereal, moonlit feel. The blooms float above strap-like foliage, offering a refined, almost otherworldly presence.

How to plant

When to plant

Plant Hymenocallis bulbs in spring, after the danger of frost has passed and the soil starts to warm. In mild climates, this can sometimes be done earlier, but avoid cold or damp ground that may rot the bulbs.

Where to plant

Choose a spot with full sun to light shade. Hymenocallis prefers bright conditions for flowering, while cooler root zones benefit from light mulching or soil shading. Ensure the area has excellent drainage—standing water can damage bulbs.

Preparing the soil

Loosen the soil to a depth of 20–25 cm, removing stones, roots, and compacted patches. Enrich with compost or well-rotted organic matter to improve fertility and texture. If your soil tends to retain moisture, mix in grit or coarse sand to enhance drainage.

Planting the bulbs

Set each bulb with its growing point facing upward and bury it about 10–15 cm deep. Space bulbs approximately 20–25 cm apart. In containers, choose a deep pot with good drainage and a rich, light potting mix.

After planting

Water thoroughly to settle the soil around the bulbs. Then keep the soil evenly moist—not soggy—especially during the early growth period.

During growth & blooming

Leaves appear first, followed by tall stalks bearing spectacular blooms. Feed lightly when flowering begins to support healthy growth and repeat blooming if possible. Remove spent flowers to maintain a tidy display and encourage energy to flow back to the bulb.

After blooming / end of season

Allow foliage to yellow and die back naturally — this is essential for replenishing the bulb’s energy. In colder regions, lift the bulbs after leaves die, dry them gently, and store in a cool, dry place until spring. In frost-free areas, bulbs may remain in place with a protective mulch.

Extra tips

Plant Hymenocallis in groups to make the floating white blooms more impactful. They are excellent near water features or in partly shaded beds where their luminous white flowers contrast beautifully with darker foliage. Because their roots prefer cool soil conditions, avoid placing them in excessively hot, exposed ground. Rotate container plantings for even light and performance. Over time, with proper care, Hymenocallis will give you several seasons of refined, moonlit blossoms.
