Rain Lily
Zephyranthes candida
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
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.
No pruning needed beyond removing occasional tattered leaves; leave the grassy clumps intact and let bulbs multiply.
A light spring feeding of bulb fertilizer boosts flowering; otherwise minimal.
Essentially pest-free; the bulbs rot only in constantly soggy, poorly drained soil.
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

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