New listing for 2023. The D’Artagnan Cherry is a cold-hardy sour cherry that produces small, sweet dark-red berries that are ready for harvest in early August. It is typically high-yielding and the berries are good for fresh eating, or in preserves and desserts. The D’Artagnan Cherry is from the new Musketeer Series from the University of Saskatchewan. Cross pollinates well with ‘Romeo’ or ‘Juliet’ sour cherry.
