''Sego'' is derived from the Shoshone word ''seego''. The sego lily was commemorated by the Sego Lily Dam, a flood-prevention infrastructure project in the shape of a giant sego lily, built in Sugar House Park in Salt Lake City in 2017.


Cultivation

''Calochortus nuttallii'' is cultivated as an ornamental plant for its attractive tulip-shaped flowers and to attract/support native pollinator species. 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.
