Lily Family

31 speciesOrder Liliales8+ well-known plants

The lily family in the traditional broad sense — now split into many families, but often used for bulbous monocots with showy 6-tepalled flowers. Includes true lilies (Lilium), tulips (Tulipa), and many ornamental bulb plants. Most grow from bulbs, corms, or rhizomes in temperate regions.

Key pattern

Three sepals and three petals identical in size and colour (reading as six petals), six stamens, and a superior three-chambered ovary.

Many true lilies grow from a starchy bulb — but several unrelated, highly toxic bulb-forming plants share that trait, so a bulb alone is never a safe identifier.

Family identification method

To check whether a plant belongs to Liliaceae, compare the leaf arrangement, leaf type, flower symmetry, fruit type, and one distinctive marker together. A single feature can mislead; the family pattern is the combination.
