Discussion | Delphinium barbeyi hybridizes extensively with D. glaucum in western Colorado and eastern Utah, where plants appearing to be hybrid [D. ×occidentale (S. Watson) S. Watson] are often far more common than plants of either putative parent. Several other names have been used for these plants, including D. elatum var. occidentale S. Watson, D. abietorum Tidestrom, and D. scopulorum subsp. occidentale (S. Watson) Abrams. Delphinium barbeyi is also known to hybridize with D. ramosum and D. sapellonis.
