* Species: Some species of lilies are naturally longer-lived than others. For example, the Madonna lily (Lilium candidum) can live for up to 10 years, while the Tiger lily (Lilium lancifolium) typically only lives for 2-3 years.
* Growing conditions: Lilies prefer to grow in well-drained soil with a pH of 6.0-7.0. They also need full sun to partial shade and regular watering. If lilies are not given the proper growing conditions, their lifespan may be shortened.
* Care: Lilies need to be fertilized regularly and protected from pests and diseases. If lilies are not properly cared for, their lifespan may be shortened.
With proper care, lilies can live for many years and provide beautiful blooms each spring.
