In the United States, it occurs in Washington, Oregon, California, Nevada, Idaho, and New Mexico. Range extent was estimated to be 1.8 million square kilometers, using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1993 and 2024 (Collins et al. 2020, CCH2 Portal 2024, GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024). | ||||||||||
