Rain Lily

Zephyranthes candida

Rain Lily

Magical white blooms pop up seemingly overnight after summer rains, earning this charming bulb its evocative name.

Hardy in USDA zones 7-10; an evergreen-clumping bulb in the low desert that tolerates light frost and returns dependably, suited to low and mid elevations.

AMWUA Notes

A low-water bulb that rewards a single post-drought soak with a burst of bloom, ideal for edges and containers.

Care Guide

πŸ’§Watering

Water every 1-2 weeks in the warm season; a deep soak after a dry spell triggers a fresh flush of blooms, mimicking the monsoon rains it is named for.

βœ‚οΈPruning

No pruning needed beyond removing occasional tattered leaves; leave the grassy clumps intact and let bulbs multiply.

🌱Fertilizing

A light spring feeding of bulb fertilizer boosts flowering; otherwise minimal.

πŸ›‘οΈPests

Essentially pest-free; the bulbs rot only in constantly soggy, poorly drained soil.

β˜€οΈSeasonal Notes

The grassy evergreen clump persists year-round in mild winters, with bursts of white flowers following summer rains and irrigation; divide crowded clumps every few years.

Soil, Feeding & Propagation

πŸͺ¨Soil

Average to sandy, well-drained soils; tolerant of poor ground; bulbs rot only in constantly soggy soil.

πŸ’§Drainage

Needs well-drained soil.

🌱Nutrient Needs

Low feeder.

🌰Propagation

Division of bulb offsets (divide crowded clumps every few years) or seed; multiplies readily into clumps.

πŸ“Spacing

1 ft

🌳Roots & Placement

Minimal; a clumping bulb that multiplies slowly with no invasive spread.

Placement Tips

  • β€’Edge borders, paths, and containers with the tidy grassy clumps for a neat, evergreen ribbon.
  • β€’Plant bulbs in tight groups so the surprise post-rain flushes read as a mass, not scattered dots.
  • β€’Combine at the front of beds with taller perennials that rise behind the low foliage.
  • β€’Full sun to light shade; well-drained soil keeps the bulbs healthy.
