Crinum asiaticum (Giant Lily) is a bulbous perennial boasting umbels of 20-30 deliciously scented, spidery-looking, pristine white flowers, 6-8 in. across (15-20 cm), adorned with slender petals and remarkably long protruding stamens with red filaments. Blooming from summer to fall (sometimes year-round in warm winter areas), the blossoms rise atop leafless scapes, well above the foliage clump of evergreen, semi-erect, strap-shaped, fleshy leaves. Adding flare to borders, Giant Lily is also a terrific marginal plant for ponds and streams.

  • Grows up to 4-6 ft. tall and wide (120-180 cm).
  • Performs best in full sun in moist, organically rich, well-drained soil. Best growth occurs in full sun, but some light shade is appreciated during the heat of the day in hot summer areas. This plant tolerates poor soils, salt, and drought.
  • Excellent choice for moist garden areas, water gardens, near ponds and streams.
  • Reliable, easy to grow, generally disease and pest-free.
  • However, watch out for slugs and snails or leaf scorch.
  • Native to tropical Asia.
  • Ingestion may cause mild stomach upset.
