There are three species in color of white, pink and yellow found in the Zion Region.
Segolily Mariposa
2. YELLOW MARIPOSALily Family
Calochortus nuttallii var. aureus
Found only in the petrified forest of the Coalpits Wash section of Zion National Park, this plant is not very abundant and probably suffered from overgrazing by livestock during the settlement period before Zion became a National Park.
Mariposa in Spanish means butterfly.
This species with bright-yellow flowers is associated with a specific geologic stratum—the Petrified Forest member of the Chinle formation. It is found in great abundance in the Petrified Forest National Monument near Holbrook, Arizona.
