A lily is a type of flowering plant. There are many species of lilies, like water lilies and tiger lilies. Most lilies grow from a bulb, which is sometimes eaten as a food. Lily is the general term for the perennial plant, from the Latin lilium. The lily has a long stem, and its funnel-shaped flower blooms in summer. Lilies grow in Europe, North America, and Asia. There are more than 100 kinds. They also come in various colours. It tends to grow wild in the forest and a grassy plain of a mountainous area, but several kinds grow wild on wet ground. A lily's petals come in multiples of three.
