Hymenocallis caribaea, the Caribbean spider lily, is a bulbous perennial in the amaryllis family grown across India as a hardy ornamental for borders, pond margins and large pots. It forms dense clumps of arching, glossy green strap-shaped leaves from which tall flower stalks emerge.
Each stalk carries a cluster of striking white flowers with long, narrow, recurving petals and a central cup-like membrane joining the stamens, giving the bloom its distinctive spider-like look. The flowers are sweetly fragrant, especially in the evening, and appear mainly through the warm monsoon and summer months.
Tough and low-maintenance, it tolerates heat, humidity and occasional waterlogging, making it well suited to most Indian plains and coastal gardens.
