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.) |
Varieties 2 (2 in the flora). Ribes cereum has a notably spicy odor. The bright green style, which becomes brown with age, is striking. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
