Of conservation concern. Eriogonum nortonii is a rare and localized species restricted to the Gabilan Range of Monterey and San Benito counties, from Fremont Peak south to The Pinnacles. It is confined largely to two protected areas, the Hastings Natural History State Reservation and the Pinnacles National Monument. A disjunct population is found southeast of Carmel Highlands in the Santa Lucia Mountains of Monterey County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum bicolor is common from Castle Valley and the San Rafael Swells of Carbon and Emery counties, Utah, eastward to Grand Valley of Grand County, Utah, and Mesa County, Colorado. It occurs to the south in Garfield, San Juan, Sevier, and Wayne counties of Utah, especially in Canyonlands National Park and the Grand Staircase-Escalante National Monument. The species is worthy of cultivation, although being a slow-growing perennial of rather specialized soils it is a challenge. Seed germination in garden plots is reasonably successful; transplanting is difficult. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
