Facts

Bristly swamp currant is a widespread but not especially common shrub that inhabits cool, moist climates in northern states and at high elevations. Although people do not make much use of the disagreeable-tasing berries, birds, deer, and rodents eat them.

Habitat

Forests, shores of rivers or lakes, swamps, talus and rocky slopes, wetland margins (edges of wetlands)

6.  Ribes lacustre (Pers.) Poir. N

bristly swamp currant. Limnobotrya lacustris (Pers.) Rydb.; Ribes oxyacanthoides L. var. lacustre Pers. • CT, MA, ME, NH, VT; also reported from RI by Gould et al. (1998), but specimens are unknown; confined to the western portion of southern New England states. Swamps, wetland borders, forests, rocky slopes, shorelines, ascending to high elevation in the mountains. This shrub is very distinctive in its branches being densely beset with slender prickles. Only Ribes cynosbati rarely shows this feature, but that species has gray to gray-brown branchlets (vs. yellow-brown or red-brown branchlets).

Native to North America?

Yes

Sometimes confused with

Ribes glandulosum:
stems unarmed, inflorescences ascending to erect, and berries dark red (vs. R. lacustre, with stems armed with thin prickles, inflorescence spreading to drooping, and berries purple to black).
