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 lasianthum occurs in the Transverse Ranges and Sierra Nevada of California and western Nevada. The petals and stamens are closely appressed and form a tube.
