Range

Cistanthe umbellata is native to western North America from British Columbia to California to Colorado, where it grows in a number of habitat types, including areas inhospitable to many other plant types, such as those with alpine climates.

A small subgroup of C. umbellatum are located in the Zayante Sandhills, a biological island in the Santa Cruz Mountains.[6] These individuals reside on a singular hill in the entirety of the sandhills, and their frail petals and loose seeds allow for easy wind dispersal.

Habit

It is a perennial herb forming generally two or more basal rosettes of thick, spoon-shaped leaves each a few centimeters long. The inflorescence arises from the rosette, a dense, spherical umbel of rounded sepals and four small petals.

C. umbellata usually has only one inflorescence per basal rosette; the related Cistanthe monosperma generally has more than one.[7]

gollark: Not that that's actually a problem most of the time, honestly.
