Different-colored blossoms on the same plant, which suggests the yellow is a color variant. Lupinus spp., probably L. arbustus , which occurs widely in the mountain West and has blossoms ranging from white to bluish. Blue Mass Scenic Area in extreme eastern Nevada.

Lupinus spp. I don't know if this is a separate species from the usual one around here or just a color variant. The inset shows an individual with both yellow and the more usual bluish-lavender blossoms. Blue Mass Scenic Area in extreme eastern Nevada. Edit: On further research, it seems to be L. arbustus , which has a range of flower colors and which occurs widely in the mountain West.

Probably longspur lupine, Lupinus arbustus , off the Pacific Crest Trail north of the Sierra Buttes, California. It is probably _not_ yellow bush lupine because of this alpine location--not to mention the shrub is much smaller. It's a bit incongruous, nonetheless, when you're expecting lupines to have blue flowers!

Hah-CHOO! Chrysothamnus spp., probably Chrysothamnus viscidiflorus . A common shrub in the sagebrush steppe that flowers in late summer and early fall, and for many people (including yours truly) is right up there with ragweed as an allergen. As the flowers ripen later in the fall the bright yellow color fades. It's an important colonizer species. This particular specimen is off the road to Cow Canyon in the southern Toiyabe Range, Nevada, but it's _everywhere_. We have some in our yard!

Wyethia spp. Often called "sunflowers" locally, and per Wikipedia they're indeed related. A common flower in Northern Nevada, they pretty much like the same conditions the sagebrush does, maybe a tad wetter. They can add quite a splash of yellow to a meadow! The name comes from the broad tapered leaves. The gray-green fronds in the background are sagebrush.
