The red spider lily is a stunning bulbous perennial that sends up dramatic, spidery red blooms in late summer or early autumn. Its foliage typically emerges after the flowers fade and stays green through the winter. It is a classic choice for adding a pop of color to your garden when other plants are winding down.

Care

Plant your bulbs with the neck just above the soil surface in a spot with good drainage. Keep the soil moist while the leaves are present during the winter, but let it dry out during the summer dormancy. Watch for yellowing leaves as a sign of overwatering or poor drainage.

Watering
Water regularly during the active growing season in fall and winter.
Feeding
Apply a balanced fertilizer in autumn as the new leaves emerge, and optionally again in late winter while the foliage is still green.
Pruning
Remove dead foliage only after it has turned yellow and withered naturally.
Repotting
Only repot when the bulbs become too crowded and flowering begins to decline.

    Growing it

    Propagation
    division
    When to plant
    late summer, early autumn
    Overwintering
    In colder regions, apply a light layer of mulch to protect the bulbs from deep freezes. Ensure the soil remains well drained to prevent rot during wet winters.
    In containers
    They grow well in containers if provided with excellent drainage and a deep pot to accommodate root growth.

    Bulb Division

    1. 1. Wait until the foliage has completely died back in late spring.
    2. 2. Carefully dig up the clump of bulbs without damaging the roots.
    3. 3. Gently separate the offsets from the parent bulb.
    4. 4. Replant the bulbs immediately at the same depth they were previously growing.

    Pair with low growing perennials that fill in the space after the lily foliage goes dormant in late spring.

    Grows well with

    • Daylily · They provide foliage cover once the lily leaves die back.
    • Liriope · The evergreen grass like foliage hides the bare soil during the lily's dormant phase.

    Similar species

    • Golden Spider Lily · It is a closely related species with similar growth habits but yellow flowers.

    Questions people ask

    Why do my lilies have no leaves?
    The leaves appear after the flowers fade, so it is normal to see bare stalks during bloom.
    How deep should I plant the bulbs?
    Plant them with the neck of the bulb just at or slightly above the soil surface.

    Where the name comes from

    The name Lycoris refers to a sea nymph in Greek mythology, while radiata describes the radiating arrangement of the petals.

    Good to know

    • These are often planted in cemeteries in Japan, leading to the nickname grave lilies.
    • The leaves emerge in autumn and persist through winter before dying back in late spring.
    • They are famously associated with the arrival of the autumn equinox.
