Type of FlowersSego Lily:
The Sego Lily ( Calochortus nuttallii ), is a bulbous perennial which is endemic to the Western United States. It is the state flower of Utah adopted on March 18, 1911.
The Sego Lily has 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. These appear in early summer. Plants are around 15–45 cm (6–18 inches) in height and have linear leaves.
The bulbs of this and other Calochortus species were roasted, boiled or made into a porridge by Native Americans and were also used as a food source by the Mormon pioneers in Utah. Currently, it is grown as an ornamental for its attractive tulip-shaped flowers.
The plant is native to a number of western states including Idaho, Montana, Wyoming, North Dakota, South Dakota, Nebraska, Nevada, Utah, Colorado, Arizona, and New Mexico.
The Sego Lily 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.
