|Lilium superbum in the Great Smoky Mountains National Park, North Carolina|
Lilium superbum is a species of true lily native to the eastern and central regions of North America. Common names include, Turk's cap lily, turban lily, swamp lily or American tiger lily. The species is native from New Hampshire south to Florida, and west to Missouri and Arkansas.
Lilium superbum grows from 3–7 feet (0.91–2.13 m) high, with typically 3 to 7 blooms, but exceptional specimens have been observed with up to 40 flowers on each stem. It is capable of growing in wet conditions. It is fairly variable in size, form, and color. The color is known to range from a deep yellow to orange to a reddish-orange "flame" coloring, with reddish petal tips. The flowers have a green star at their center that can be used to distinguish L. superbum from the Asiatic "tigerlilies" that frequently escape from cultivation.
