Its habitat includes chaparral, woodlands, and forested areas.[3][4]DescriptionRibes roezlii is a spiny shrub growing erect to a maximum height around {{convert|1.2|m|ft}}. The hairless to hairy or woolly leaves are up to 2.5 centimeters (1 inch) long and divided into 3 or 5 rounded, toothed lobes.[3][6][7]The inflorescence is a solitary flower or raceme of 2 or 3 small wind-pollinated[5] flowers hanging pendent from the branches. Each flower has five reflexed red-purple sepals around a tube-shaped ring of smaller white or pinkish petals, the stamens and stigmas protruding.[3][6][7][8] The fruit is a red or purple berry up to 2.5 centimeters long which is covered in thick, long spines. Among other currants and gooseberries with overlapping ranges, such as mountain gooseberry (Ribes montigenum) or wax currant (Ribes cereum), the sierra gooseberry is especially notable for the large size and extreme spininess of its berries,[9] and for the absence of a noticeable dried flower remnant at the end of the fruit.[6][7] Seeds are dispersed by running water and by animals that eat the fruits, such as American black bears.[5] The foliage is an important food source for mule deer and bighorn sheep, and the fruits are a common food for fox sparrows living in its range.[5][6][7] References1. ^Tropicos, Ribes roezlii Regel 2. ^{{PLANTS|id=RIRO|taxon=Ribes roezlii|accessdate=22 October 2015}} 3. ^1 2 Calflora taxon report, University of California: Ribes roezlii . accessed 1.30.2013 4. ^Biota of North America Program 2014 county distribution map 5. ^1 2 US Forest Service Fire Ecology 6. ^1 2 3 Flora of North America, Ribes roezlii 7. ^1 2 3 [https://www.biodiversitylibrary.org/page/40100001#page/282/mode/1up Regel, Eduard August von 1879.
