Cherries are a healthy and refreshing fruit of late spring and summer. There are nearly 1,000 different varieties of cherry trees in the United States alone, which were brought over by English colonists in the 1600s. Cherries are a stone fruit that are closely related to peaches, apricots and nectarines. In many parts of North America, the cherry is among the first tree fruits to ripen; hence the colloquial term “cherry” to mean “new” or “the first.” The most popular cherries picked for eating are wild cherries, which are on the sweet side, and sour cherries, which are primarily used for cooking or to make jam. Cherries are a seasonal fruit that have a very short fruiting season beginning in late April and ending in early June.
