Discussion | Subspecies 2 (2 in the flora). Although Delphinium menziesii has often been confused with D. nuttallii, it may be distinguished by its consistently larger flowers and usually fewer flowers per plant. Interestingly, each species produces both blue-purple and yellowish flower colors in separate populations. The Chehalis consider Delphinium menziesii poisonous, but they also apply it to sores. The women of the Thompson Indians use it as a love charm (D. E. Moerman 1986, subspecies not indicated). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Delphinium wootonii hybridizes with D. madrense in the eastern Big Bend area of Texas, and with D. carolinianum subsp. virescens. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
