Red currants are commonly cultivated in N.Z. although they are not as abundant or important as black currants. However, they are more likely to occur wild than are black currants. White currants are occasionally grown and represent 1 or more cvs of R. rubrum; they differ from red-fruited cvs only in the fr. colour. White currants are wild near Mt Cook, Canterbury, and Lake Wakatipu in C. Otago. Red currants are sometimes referred to R. sativum (Reichb.) Berger or R. vulgare Lam. but these names are usually treated as synonyms of R. rubrum now.
