Endemic to the Canyonlands of south-central Utah, where known from five occurrences in two distinct clusters: one in the southern portion of the San Rafael Swell in southern Emery County (administered by the BLM) and the other in Capitol Reef National Park in central Wayne County. Approximately 3,000 plants are known, but this may be an underestimate since this species occurs on difficult terrain. The Emery County occurrences are threatened by habitat degradation associated with uranium mining claim annual assessment work (an access road bisects the population); degradation could become more severe in the future if abandoned uranium mines near these occurrences were ever reopened. The Wayne County occurrences are vulnerable to trampling by hikers.

Only two known populations known, totaling approximately 2000 individuals. (Clark and Groebner 2000)
Currently managed by the BLM and Park Service at Capitol Reef National Park.
This plant has not yet been germinated from seed. Tissue culture might be tried.
