Phenology
Plants flower from July to August (sometimes September)
Species range
This species can be found throughout the Rocky Mountains and within the state of Colorado, Idaho, Montana, Nebraska, Nevada, Utah, Washington and Wyoming. In Utah, the species can be found in Daggett, Duchesne, Garfield, Salt Lake, Tooele, Uintah, Utah, Wayne and Weber Counties.
Threats or limiting factors
Current threats include competition from invasive species, vegetation succession, hydrology change: flood control, water development/redevelopment, and stream/riparian restoration [where plants are dependent on current, altered conditions, road maintainenece, recreation, natural herbivory (e.g. by voles), loss of habitat due to urbanization, loss of pollinators (reduction in the quantity and suitability of available pollinators, particularly certain bees), grazing, drought, and haying/mowing (Fertig et al. 2005). Approximately 60% of occurrences are affected by one or more "current threats", while an additional 12% of occurrences are not affected by any "current threats" but have one or more "potential threats" listed, bringing the total to 72% of occurrences thought to be threatened in the present or near future. Competition from invasive species, the most widespread single threat, affects 62% of occurrences and 84% of individual plants (Fertig et al. 2005). Although this species is now thought to be more resilient to human-influenced environments than was originally supposed, many threats remain high.
