About Rain lily
Zephyranthes robusta, also known as "robust rain lily" or "zefyrovka mohutná", is a charming perennial bulbous plant belonging to the Amaryllidaceae family, native to South America. It produces large, solitary, and attractive bright pink or fuchsia flowers that emerge rapidly after rainfall, hence its nickname "rain lily". It is ideal for garden borders, rockeries, or in pots, where its ephemeral yet spectacular blooms can be admired.
Native range
South America, mainly in Brazil, Argentina, Paraguay, and Uruguay.
Care tips
It requires full sun to light partial shade for optimal flowering. Watering should be moderate during growth and blooming, and reduced during dormancy, avoiding waterlogging that can rot the bulb. It prefers well-drained, sandy soil rich in organic matter; a common mistake is planting them in heavy, poorly aerated soils. Protect the bulbs from severe frosts in cold climates.
