Notes

USDA Plants National Database recognizes five subspecies of O. cespitosa, all native to the southwestern U.S. Subspecies crinita is found in California, Nevada, Utah and Arizona. Subspecies cespitosa, navajoensis, marginata, and macroglottis are native to many of the southwestern states including Colorado; the latter two can be found in the Fort Collins area. They all vary slightly in appearance in flower size, hairs and leaf shapes.


Flowers fade to dark rose-purple. Allow to move around garden to regenerate, rosettes are short lived.


This is an important adult food host for many of our native invertebrates.
