|discussion=<p>At the sites in Manitoba and Saskatchewan, <i>Delphinium glaucum</i> is naturalized, not native.</p><!--
--><p><i>Delphinium glaucum</i> hybridizes extensively with <i>D. barbeyi</i> in Utah and Colorado to the extent that hybrids [D. ×occidentale (S. Watson) S. Watson] are more common in many areas than individuals of either parental stock. It occasionally hybridizes with <i>D. distichum</i>, <i>D. polycladon</i>, <i>D. ramosum</i>, and <i>D. stachydeum</i>. Hybrids with <i>D. brachycentrum</i> are called D. ×nutans A. Nelson.</p><!--
--><p>Tremendous variation is apparent in what is here recognized as <i>Delphinium glaucum</i>. This is the northern expression of the complex described in the discussion under <i>Delphinium sub</i>sect.<i> Exaltata</i>. Although some geographic patterns are apparent in the variation within <i>D. glaucum</i>, infraspecific entities are not here recognized. Apparently because of rather recent and/or incomplete genetic isolation, the degree of differentiation between these units is not such that they can be consistently recognized.</p><!--
--><p>Specimens named <i>Delphinium</i> splendens represent plants grown in high-moisture, low-light conditions and may occur as sporadic individuals anywhere from California to Alaska. Type specimens of D. brownii Rydberg, D. canmorense Rydberg, and D. hookeri A. Nelson represent plants grown on relatively dry sites at high latitudes. Plants from dry sites at low latitudes are represented by D. bakerianum Bornmüller and D. occidentale var. reticulatum A. Nelson. Plants with lavender to white flowers are represented by type specimens of D. brownii forma pallidiflorum B. Boivin and D. cucullatum A. Nelson. Type specimens of D. alatum A. Nelson and <i>D. glaucum</i> <i></i>var.<i> alpinum</i> F. L. Wynd (an invalid name) represent plants growing above or near treeline.</p><!--
--><p><i>Delphinium glaucum</i> may be confused with <i>D. californicum</i>, <i>D. exaltatum</i>, <i>D. polycladon</i>, or <i>D. stachydeum</i>. For distinctions from <i>D. californicum</i>, see discussion under that species. Absence of basal or proximal cauline leaves, generally much larger plants (greater than 1.5 m), more flowers in the inflorescence, and shorter petioles on the leaves of <i>D. glaucum</i> are features that serve to distinguish this species from <i>D. polycladon</i>. In the latter, the leaves are primarily on the proximal stem, plants often less than 1.5 m, flowers more scattered, and petioles more than twice the length of leaf blades. Features of the sepals may be used to distinguish <i>D. glaucum</i> (dark lavender to blue purple, usually only minutely puberulent) from <i>D. stachydeum</i> (bright blue, densely puberulent). Vegetative parts of <i>D. stachydeum</i> are also densely puberulent, while those of <i>D. glaucum</i> typically are glabrous.</p>
