|discussion=<p>Delphinium nuttallianum represents an extremely difficult complex, with many variations in a number of morphologic traits. The complex has been and continues to be a major source of confusion for identification of Delphinium in North America. Type specimens of D. nuttallianum represent plants growing under dry conditions in open areas. These are typically found at 1200-2000 m in sage scrub or lower montane forest. Delphinium nuttallianum may be confused with D. andersonii, D. antoninum, D. depauperatum, D. gracilentum, and two subspecies of D. patens (subsp. patens and subsp. montanum). Features that may be used to separate D. nuttallianum from the first four, are enumerated under the respective species discussions. From D. patens subsp. patens, D. nuttallianum may be distinguished by its narrower leaf lobes, larger fruits, and more compact inflorescence. The frequent presence of glandular hairs in the inflorescence of D. patens subsp. montanum, contrasted with their absence in D. nuttallianum, will separate these taxa. Dwarfed plants of D. polycladon may be confused with D. nuttallianum. The latter, however may be distinguished by its ringed seeds, and it does not have prominent buds or sigmoid pedicel.</p><!--
--><p>Hybrids have been seen between Delphinium nuttallianum and D. andersonii, D. depauperatum (D. ×burkei Greene), D. distichum (D. ×diversicolor Rydberg), D. nudicaule, and D. polycladon.</p>
