Overview

True lilies are perennials from the genus Lilium and grow from bulbs made of fleshy segments called scales. Lilies can bloom from early summer through fall, depending on the species. Some types are extremely fragrant. Lilies make excellent cut flowers.

Significance

Lilies symbolize hope and the miracle of new life. During the Middle Ages, they were often shown in religious artwork. The ancient Greeks used the flower as a symbol of sexuality.

Types

Lilies are generally placed in two categories--garden lilies and native lilies. Many of the native lilies found in the United States have been cultivated successfully in the garden.

Features

Most lily bulbs produce thick, fleshy roots that contract. The contracting action pulls the bulb deeper into the soil. This helps to preserve the bulbs in extreme weather.

Effects

Lilies are sometimes affected with botrytis, a fungus that mars the leaves in continued wet conditions. Adequate circulation can prevent this disease.

Propagation

Lilies create new plants each year by offsetting bulbs. These bulbs can be harvested and replanted. It may take 2-3 years before the new plants flower.
