Zephyranthes or Rain Lily: A hardy bulb for pot and rock gardens
Zephyranthes are hardy bulbs that range from 5 cm to 30 cm in height. This makes them great for using in rock gardens. When in bloom, plants carry pink, red, white, or yellow funnel shaped flowers.
Zephyranthes or Rain Lily is a bulbous perennial in the Amaryllis family that is native to southern North America south to Central and South America. There are over 70 species along with numerous hybrids and cultivars. In the wild, plants often burst into bloom immediately following periods of significant rain, hence the common name.
These bulbs prefer well-drained soils in sun to part shade and bloom in spring, summer or fall depending on the species. Many bloom from summer to fall. The flowers come in white, yellow, and shades of pink. Most have grass-like foliage but some species have wider leaves. They are listed as hardy in zones 7-10 but some may tolerate colder temperatures.
Use in rock gardens, borders, pathways or small spaces. They can also be used in containers and brought indoors if desired.

It is quite easy to look after Zephyranthes species such as Rain and Zephyr lilies. They like 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.
