Phenology | Flowering spring (-early summer). | Flowering summer, more than 8 weeks after snowmelt. |
Habitat | Basaltic cliff faces, n and e slopes at base of cliffs | Old homesites |
Elevation | 200-500 m (700-1600 ft) | 50-3000 m (200-9800 ft) |
Distribution |
OR; WA |
BC; MB; SK; and probably elsewhere; native to Europe and w Asia [Introduced in North America] |
Discussion | Of conservation concern. Hybrids between Delphinium basalticum and D. trolliifolium are known. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Delphinium elatum is cultivated as a garden plant or for cut flowers. It is not known to be naturalized extensively in North America; it may persist long after cultivation in cooler parts of the region. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
