Pancratium zeylanicum is a bulbous[2] perennial herb, which grows in India and on the islands of the Indian Ocean east to insular Southeast Asia. It has been collected from India, Sri Lanka, the Maldive Islands, the Laccadive Islands, Borneo, Java, Maluku, Sulawesi and the Philippines.[3]

Pancratium zeylanicum is known commonly as "rain flower". It is sometimes grown as a hothouse container plant. It does not have a rest period unless water is withheld. It propagates by producing offsets and seed.

The pollinator is a moth with a very long proboscis. Flowers are white with narrow tepals and long teeth along the margin of the staminal corona.[4]
