Discussion | 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.) |
Of conservation concern. Delphinium hutchinsoniae is known from only a few populations near Monterey and south to the Big Sur region. Hybrids have been produced between D. hutchinsoniae and D. cardinale grown in a common garden. Hybrids also occur with D. parryi subsp. maritimum. Delphinium hutchinsoniae is similar, and probably closely related, to D. variegatum. The two may be distinguished by the decurved spur of D. hutchinsoniae; the spur of D. variegatum is normally straight (or decurved nearer apex). Delphinium hutchinsoniae lacks marginal hairs on lower petals; such hairs are present in D. variegatum. The two species are also geographically separated.
