Denver Botanic Gardens holds at least one conservation seed collection of this species, originally collected in 1987. Denver Botanic Gardens plans to recollect seed from this 34 year old accession as part of CPC's IMLS-funded seed longevity project that will evaluate how the germination rates and RNA integrity of this species endures in long term seed storage.
Currently twenty-one documented occurrences, however these within a restricted range. More occurrences known. Found only on the Uncompahgre Plateau (approximately 300 square miles). Colorado National Monument and Rough Canyon Natural Area each contain one population. Insect infestation may threaten reproductive viability at one site.
Insect herbivory may pose a threat (Pers. Comm. 1987).
Documented twenty-one occurrences, most near Grand Junction (Mesa, Delta, and Montrose Cos.) (Pers. Comm. 1987).
Karron (1987) compared pollination in this rare species and its more widespread relatives. He hypothesized that this species may be a poorer competitor for pollinators, and that this factor may help to maintain its rarity.
