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.

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.
