How to Grow Rain Lily and other Zephyranthes
It is best to grow Zephyr lily and other Zephyranthes plant species from bulbs as they will not flower for about three or four years if grown from seed.
The bulbs should be planted at a depth of 8 cm (3.25 inches) to 10 cm (4 inches), and a spacing of 10 to 15 cm (4 to 6 inches) apart, following the last frost of spring.
If sowing Rain lily seeds, then do so in either spring or autumn. Lightly cover the seed once sown.
Plants are able to grow in partially shaded or sunny parts of the garden. They require good drainage.
Ideally the soil should be moist, rich, and have a pH of 6 to 7.
If you want to start plants off indoors, then it should take them about 15 weeks to germinate at a temperature of 15 to 20 degrees Celsius (59 to 68°F).
Once established, transplant into the garden in either autumn or spring.
Caring for Zephyr lilies
It is quite easy to look after Zephyranthes species such as Rain and Zephyr lilies. They enjoy a moist soil - so water regularly in dry periods; give them a feed in the spring, and supply a mulch in the autumn to help protect the bulbs from harsh winters.
If you require more plants then propagate by planting the offsets that they produce.
