Lilium /ˈlɪliːəm/

Common name: Lily (true lily)

Lilium is a genus of around 100 species of bulbous perennials in the lily family (Liliaceae), native to temperate regions of the Northern Hemisphere. True lilies grow from scaly bulbs and produce tall, unbranched stems topped with large, often fragrant, trumpet- or bowl-shaped flowers. Only members of this genus are "true" lilies; daylilies, calla lilies, and lily-of-the-valley belong to other families.

Fun facts

  • Lilies are among the most dangerous plants for cats — even pollen or vase water can cause kidney failure.
  • Lily bulbs have no protective tunic (paper skin), so they must be planted promptly and never allowed to dry out.
  • Lilies have been cultivated for over 3,000 years; the Madonna lily appears in ancient Minoan art.
  • In Asia, bulbs of several Lilium species have long been eaten as a starchy vegetable.
