More about this plant

Berry Blue is a tall, vigorous, early-ripening Russian cultivar historically used as a pollenizer because it carries many flowers. Its fruit becomes less tart when fully ripe. Bloom timing limits some pairings: Aurora is listed as a pollenizer, while Berry Blue was a poor companion for the later Boreal Beauty.
