About plant names...

The sego lily is Utah’s state flower.

Identification: Each lily has one to four flowers, each with three white petals. The petals sometimes have a purplish tinge. The stems are straight and bare. Flowers are about 12" (30 cm) high.

Edibility: Sego lily bulbs, after removing their outer husks, are tasty raw and further improved by slow cooking; bulbs may also be dried and ground. Flowers and buds are also edible and can be added to salads. Their edibility was discovered (or rediscovered) during a cricket-induced food shortage in Utah between 1840-51, and sego lilies were later adopted as Utah’s state flower.
