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.) |
The lobed, yellowish, pinkish, or red nectary discs and purplish red filaments of Ribes montigenum are striking. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
