Lilium superbum is a species of true lily native to the eastern and central regions of North America.

[citation needed] The native range of the species extends from southern New Hampshire, Massachusetts, and New York, west to Illinois, Missouri, and Arkansas, and south to Georgia, Alabama, Mississippi, and Florida.

[3][7] Lilium superbum grows from 3–7 feet (0.91–2.13 m) high with typically three to seven blooms, but exceptional specimens have been observed with up to 40 flowers on each stem.

[10] It is listed as endangered in Florida, New Hampshire, Alberta and Saskatchewan and threatened in Kentucky, and exploitably vulnerable in New York.

[3] The Turk's cap common name is derived from the reflexed shape of the flower petals, which presumably resemble a type of hat worn by early Turkish people.
