| Discussion | Varieties 2 (2 in the flora). Ribes sanguineum is widely cultivated. It begins to bloom very early in the season, providing a nectar source for pollinators when little else is available. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Ribes canthariforme is endemic to the Cuyamaca-Laguna Mountain region of San Diego County. It has quite thick leaves. Thirteen populations are known; nine of those are historic. About 70 plants have been found in the remaining populations.
