| 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 erythrocarpum is found in the Cascade Mountains of southern and central Oregon. It was allied with R. viscosissimum and R. sanguineum by A. E. Senters and D. E. Soltis (2003), with R. acerifolium (as R. howellii) and R. cereum by W. Messinger et al. (1999), and with R. glandulosum by M. Weigend et al. (2002). Ribes erythrocarpum shares fairly shallow hypanthia and conspicuous nectary discs with R. acerifolium,R. laxiflorum, and R. glandulosum.
