Red, pink and white currants are self-fertile, meaning one plant will set fruit without any other currant varieties nearby. Pink and white currants are albino selections of red currant. The fruit of pink and white currants is generally less acidic. Some consider pink and white currants to be better for fresh eating.

Do currant bushes need a pollinator?
