Lilium superbum is a species of true lily native to the eastern and central regions of North America. [3] [4] [5] Common names include Turk's cap lily, [3] turban lily, [4] swamp lily, [6] lily royal, [6] or American tiger lily.[ 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. [4] It is capable of growing in wet conditions. [8] It is fairly variable in size, form, and color. [4] The color is known to range from a deep yellow to orange to a reddish-orange "flame" coloring with reddish petal tips. [4] 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. [5] It grows in swamps, woods, and wet meadows. [9]
The roots were a food source for Native Americans, and the flowers provide nectar for hummingbirds and larger insects. [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. [9]
Cats are extremely sensitive to lily toxicity and ingestion is often fatal; [11] [12] [13] households and gardens that are visited by cats are strongly advised against keeping this plant or placing dried flowers where a cat may brush against them and become dusted with pollen that they then consume while cleaning. Suspected cases require urgent veterinary attention. [14] Rapid treatment with activated charcoal and/or induced vomiting can reduce the amount of toxin absorbed (this is time-sensitive so in some cases vets may advise doing it at home), and large amounts of fluid by IV can reduce damage to kidneys to increase the chances of survival. [14]
The bulbs were made into soups by some Native Americans. [15]
