Other:  Sour cherry. There is good evidence suggesting that P. cerasus arose from an unreduced pollen grain of P. avium crossed with P. fruticosa; this occurred in the same geographic region as for sweet cherry. The sour cherry came to the US with English settlers, like sweet cherries. It is more tolerant of the humid, rainy eastern conditions, and therefore proliferated there more than sweets, where it is still cultivated today in greatest numbers. Sour cherries do not attain good size when grown in arid climates.
Sour cherry growers prefer the term "pie" or "tart" cherry over "sour", since this connotes bad flavor. Most sour cherries are processed into pie fillings, hence the name.
