Discussion | Of conservation concern. Delphinium viridescens is local in mountains southwest of Wenatchee, Washington. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. In addition to the Alabama sites, Delphinium alabamicum is known from one population in Georgia; it might have been transplanted there. Delphinium alabamicum has not been seen in central Alabama since 1950; populations there might have been extirpated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
