Ribes hirtellum is a species of gooseberry commonly known as wild gooseberry or swamp gooseberry. It is native to Canada and the northern United States. Cultivated gooseberries are derived from this species and from "Ribes uva-crispa".
"Ribes hirtellum" is known by several other names, including American gooseberry, hairy-stem gooseberry, hairy gooseberry, low wild gooseberry northern gooseberry, smooth gooseberry, and wedge-leaf gooseberry.
Distribution and habitat.
"Ribes hirtellum" grows in a variety of habitats, including wetlands such as fens, sedge meadows, riverbottom forests, and swamps, shorelines of streams and lakes, and rocky openings in forests and along cliffs. It grows throughout much of eastern north America, from Alberta to Nova Scotia in Canada, south to West Virginia, and west to Nebraska in the United States.
Use in gooseberry breeding.
Whereas "Ribes uva-crispa" crops have been devastated by American gooseberry mildew, "Podosphaera mors-uvae", which was accidentally introduced to Europe, "Ribes hirtellum" is resistant. It is one of four American species that have been interbred with "R. uva-crispa" to produce resistant cultivars similar to the original "R. uva-crispa" cultivars. The cultivar 'Houghton' is one of those obtained by crossing "R. uva-crispa" with "R. hirtellum".
