| 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 diacanthum was first seen as apparently naturalized in 1947 in oak woods on bluffs near the Experimental Farm, Brandon, Manitoba; collections were made in 1956 and 1959 and deposited in DAO and the Experimental Farm herbarium (G. A. Stevenson 1965). Its current status in Manitoba is not known. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
