Discussion | Of conservation concern. Delphinium viridescens is local in mountains southwest of Wenatchee, Washington. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Delphinium geraniifolium is a more pubescent analog of the closely related D. scopulorum, the former occurring in heavier soils at higher elvation. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
