The symbol of summer. Peaches are also called Persian apples, as they are believed to have originated from Persia (present day Iran). However, they have roots in China, where the peach was a symbol of longevity and prosperity. Today, China is the world's largest producer of peaches, according to the Food and Agriculture Organisation (FAO). Peaches are a summer fruit that reach their peak of ripeness in July and August, and today there are more than 100 varieties of peaches. For example, a nectarine is a type of peach, and did not arise, as it often thought, through crosses with the plum.
