Rain Lily (Zephyranthes grandiflora) is a small, charming bulb famous for flushing into bright pink, crocus-like flowers within days of rain, especially through the Indian monsoon. It forms neat grassy clumps of slender leaves and is one of the easiest, most rewarding bulbs to grow. Perfect for edging, borders, pots and rockeries, it naturalises quickly into dense, free-flowering carpets. Tough and undemanding, it tolerates heat and seasonal dryness, going semi-dormant between flushes. There are pink, white and yellow species, but the pink Zephyranthes is the most popular and reliable performer in Indian gardens.

Growing tips
Plant bulbs in clusters in spring; in India they reward the first monsoon showers with flushes of bloom, and a deliberate dry-then-water cycle triggers more flowers.
