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.
