Yes it's another of the High elevation buckwheats. Eriogonum lobbii found locally in the Sierra Nevada Range. This one grows in the Northern Sierras of CA & NV. It continues on a path across Northern CA to the coastal mountain Ranges were it just crosses the southern border of OR.
I have found this growing on Slide Mountain at 9500'-9700'. It is a low clumping/mat with rather large grayish green tomentose leaves and a long tap root. What what sets this alpine Eriogonum off from the rest is the way in which it displays it flowers. They are splayed out on the surface of the granitic scree around the plant. I have found two color forms white/cream or rosy/cherry. This seems to be easy to grow in the garden, given of course a well drained planting medium.
The pictures will show both color forms. These are from the same population
