Family: Amaryllidaceae

Crinum lily is a herbaceous, evergreen shrub with an open upright habit. An umbel of showy white flowers arises from the middle of a rosette of broad, green blades. Native to southeast Asia, the Crinum lily is cultivated in warm regions worldwide. The roots, bulbs, and leaf juice are said to be medicinal; however, another common name is poison bulb. The flowers are the perfect size to tuck behind the ear or for lei-making. There are varieties in many shapes and sizes, some with 20 to 50 flowers. It grows best in full sun with ample water and well-drained soil.
