}} Calochortus nuttallii — known as sego lily — is a bulbous perennial which is endemic to the Western United States. It is the state flower of Utah.[2] DistributionThe plant is native to a number of western states, being found throughout Utah and Wyoming, large parts of eastern Nevada, and parts of Idaho, Montana, North Dakota, South Dakota, Nebraska, Colorado, Arizona, and New Mexico.[2][3] DescriptionCalochortus nuttallii are around 15–45 cm (6–18 inches) in height and have linear leaves.[2]Plants have 1 to 4 flowers, each with 3 white petals (and 3 sepals) which are tinged with lilac (occasionally magenta) and have a purplish band radiating from the yellow base. A yellow petaled form with deep purple bands is known from Petrified Forest National Park.[5] The plant blooms in early summer, with flowers that can be up to 3 inches across.[6][7] TaxonomyCalochortus nuttallii is a species within the genus Calochortus, in a sub-group generally referred to as Mariposa Lilies. The specific epithet nuttallii, named for the English botanist and zoologist, Thomas Nuttall, was ascribed to the species by the American botanists John Torrey and Asa Gray when it was officially described in 1857.
A number of former varieties of Calochortus nuttallii have been reclassified as distinct species:
UsesCulinaryNative Americans had culinary uses for the bulbs, seeds, and flowers of the plant. Bulbs were roasted, boiled, or made into a porridge by the Hopi, Havasupai, Navajo, Southern Paiute, Gosiute, and Ute peoples.[9][10][11] The Hopi used the yellow flower ceremonially. They taught the Mormon pioneer immigrants to use the bulb for badly needed food. This resulted in the sego lily being formally designated as the Utah State Flower in 1911.[12] CultivationCalochortus nuttallii is cultivated as an ornamental plant for its attractive tulip-shaped flowers and to attract/support native pollinator species.[13] It prefers a deep, sandy soil with good drainage, and is cold-hardy. Plants can be propagated from newly formed bulblets which take two years to flower.[14]References1. ^1 Kew World Checklist of Selected Plant Families 2. ^1 {{cite web |url=http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242101485 |title=Calochortus nuttallii |accessdate=2007-11-12 |last= |first= |vauthors= |date= |work=Flora of North America |publisher=eFloras.org}} 3. ^{{cite web |title=Distribution Map |url=http://www.efloras.org/object_page.aspx?object_id=8184&flora_id=1 |website=Flora of North America |accessdate=November 30, 2018}} 4. ^1 Source: "Our State Flowers: The Floral Emblems Chosen by the Commonwealths", The National Geographic Magazine, XXXI (June 1917), p. 512. 5. ^Northern Arizona University: Petrified Forest Nat'l Park, Arizona.
