| 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 malvaceum occurs in the southern North Coast, South Coast, Transverse, and Peninsular ranges, and the Channel Islands. It has also been reported from the Sierra Nevada in Tuolumne County. Its thick, rugose leaves, which are white-tomentose abaxially and dark green adaxially, and glaucous, white-haired berries are striking. Plants with dark green leaves occurring below 800 meters have been recognized as var. malvaceum, those with bright green leaves occurring up to 1500 meters as var. viridifolium.
