Hymenocallis caribaea is naturally found in the West Indies growing on the coast along forest margins. It prefers a fertile moist well drained sandy soil in a sunny protected position and is drought and frost sensitive. 

Spider Lily is grown for its flowers and clumping habit. It is used in small or tropical gardens as a specimen or mass planted along borders. It is suitable for protected coastal regions and establishes from division in 2-3 years and is moderately long lived. This bulbous perennial may also be grown in tubs or planter boxes, rockeries, fragrant gardens or used as an understory plant tolerating semi shaded positions. Once established this perennial requires little maintenance, but needs reliable moisture. ID 584
