| 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 binominatum occurs at relatively high elevations in the Coast Ranges of northern California and the Klamath Mountains of central and southern Oregon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
