California Bearpoppy (Arctomecon californica)

General: Las Vegas Bearpoppy (Arctomecon californica), also called California Bearpoppy, is a perennial forb that only grows in gypsum-rich soils. The hairy, silvery-gray leaves grow in a clump at the base of the plant, and the large, yellow, poppy flowers grow atop long stems.

California Bearpoppy occurs on eroded, gypsum-rich soils in the Las Vegas Valley and near Lake Mead, which is in the Upper Sonoran (Mojave Desert Scrub) life zone. These plants can most easily be seen along Northshore Road (Lake Mead NRA). They also occur in the Gold Butte region, in Tule Springs Fossil Beds National Monument, and along the south side of Lake Mead near Bonelli Landing (towards Temple Bar).

Family: Poppy (Papaveraceae).

Other Names: Las Vegas Bearpoppy, Las Vegas bear poppy, California bear poppy.

Plant Form: Basal clump of leaves with several flower stalks.

Distribution: This species is endemic to the Lake Mead region of southeastern Clark County, Nevada. It can be found near Lake Mead in gypsum-rich soils.

Comments: This species has been considered for protection under the federal Endangered Species Act and is protected by state laws in Nevada, Arizona, and Utah -- don't pick or otherwise disturb bearpaw poppies!

An annoying habit of Bearpaw Poppies, a rare and protected plant, is that it grows in disturbed habitats, such as roadcuts along Interstate-15. This can cause problems for road maintenance crews and other landowners.
