Growing rain lilies is not difficult when the right conditions are available to the plant. Rain lily bulbs produce diminutive blossoms in abundance once they're settled in the right spot.
Tips for Growing Rain Lilies
Also known as Zephyr lily and fairy lily, growing rain lilies are petite, reaching no more than a foot (30 cm.) in height and rarely getting that tall. Pink, yellow and white crocus-like flowers bloom from late spring through late summer, sometimes earlier during rainy seasons. Multiple flowers bloom on each stem. This plant is hardy is USDA Zones 7-11. A member of the Amaryllidaceae family, tips are the same for growing rain lilies as for growing the crinum lily, the Lycoris lily and even the common indoor-grown amaryllis of the same family. Sizes and blooms differ, but care for rain lily is similar to other members of the family. Several types of rain lilies are available in today's market. Newer hybrids come in a range of colors, and bloom time will vary by cultivar, but basically, their care is the same.
- Plant where afternoon shade is available to the plant, especially in the hottest areas.
- Care for rain lily includes regular watering, even during dormancy.
- Soil should be well-draining.
- Rain lily bulbs should not be moved until the bed is overcrowded.

How to Grow Rain Lilies
Plant the small rain lily bulbs in well-draining soil during the fall season. Soil that is rich, holds moisture well, and is slightly acidic is preferable for this plant. Place bulbs about an inch deep and 3 inches (7.5 cm.) apart. When moving and transplanting rain lily bulbs, any time of year will work if the bulbs are planted quickly and watered in. Regular watering is important to keep the grass-like foliage of rain lily lush and healthy. Foliage may die back during periods of neglect, but usually returns when watering resumes.
