Discussion

Cultivars of Prunus cerasus with doubled flowers are used as landscape ornamentals. Most of the commercial sour cherry crop in North America comes from Michigan. Unlike sweet cherry, all widely grown varieties of sour cherry are self-fertile. Bud scales at the bases of the pedicels on flowering and immature fruiting specimens of P. cerasus often have leaflike apices and the inner scales are erect; in P. avium the scales are not leaflike and the inner ones are reflexed or spreading.
