Balsamorhiza rosea
Balsamorhiza incana
In a hybrid swarm involving Balsamorhiza rosea and B. careyana, B. rosea remains relatively uncontaminated; the dominance among the hybrids appears to lie with B. careyana. A record of a hybrid between B. rosea and B. careyana from the Spokane area is doubtful.
