Varieties 3 (3 in the flora). The California Department of Transportation is planting members of this insular species, especially var. giganteum, on the mainland, where it readily hybridizes with both E. fasciculatum and E. cinereum. Every effort should be made to remove the introduced E. giganteum from coastal California. The Avalon scrub-hairstreak butterfly (Strymon avalona), which is endemic to Santa Catalina Island, uses Eriogonum giganteum as a food plant.

Eriogonum libertini is encountered infrequently in the Dubakella and Tedoc mountains area of Tehama and Trinity counties in northwestern California. It is closely related to E. ternatum, found to the north. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
