The lily is a tough perennial, blooming mainly in the summer and thriving mostly in full sun. The plant is native to many countries, and from these plants, hybrids have been developed. Lilies are available in colors including red, pink, white yellow, orange, purple and mixed. The petals range from trumpet-shaped to bowl-shaped to flat. With the thousands of cultivars available, there is a lily to suit everyone's taste. The lily grows in USDA Hardiness Zones 3 to 8.
