Cultivars of Prunus avium are grown in North America both for their attractive flowers, especially where the Japanese ornamental cherries are not hardy, and for their sweet fruits. Most of the sweet cherry crop in North America is grown in the Pacific Coast states and in Michigan and Ontario. Most varieties are self-incompatible and require pollen from a variety in a different incompatibility group in order to set fruits.
