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.) |
Ribes nevadaense occurs in the southern and northern Coast Ranges, Transverse Ranges, and Sierra Nevada in California and western Nevada. Reports of it from southwestern Oregon are questionable. It is unusual in having pink bracts subtending the pedicels. Its leaves are much thinner in texture than those of R. malvaceum Smith.
