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.

Prunus texana is endemic to south-central Texas from the Edwards Plateau southeast to the coastal plain.

Despite the peachlike fruits of Prunus texana, DNA evidence supports its placement among the native American plums (J. Shaw and R. L. Small 2005). The leaf margins look like those of no other North American species of Prunus. The teeth project perpendicular to the margins and are capped with disc-shaped glands.
