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)
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

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).
Synonyms
- Limnobotrya lacustris (Pers.) Rydb.
