Balsamorhiza serrata hybridizes with B. careyana. Leaves of the hybrids tend to be prostrate rather than erect. Most of the hybrids display the larger size of B. careyana and lack the pubescence of the heads; serrata-like plants never develop more than a single head nor do they have the pubescence of the cypselae.
