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. Delphinium bakeri is possibly extinct in the wild because of cultivation and sheep grazing in the small area where it grows. It is known from only two localities and has not been collected since 1960. Plants have been grown at Strybing Arboretum, Golden Gate Park, San Francisco. Although their geographic ranges are distinct, D. bakeri is most similar to, and probably closely related to, D. trolliifolium. The former has more rounded incisions on the leaves than the latter, and the pedicel of D. bakeri are consistently glandular. Glandular pedicel appear only occasionally in D. trolliifolium.
