Peaches are actually not considered to be tropical fruits but rather from the Rosaceae family which includes a number of temperate fruits. Both white and normal peaches are from this family as well as the nectarine which has strong ties with peaches.
The Rosaceaea family includes a wide range of medium-sized flowering plants, including peaches. They are not in fact considered to be tropical fruits as many people think but rather temperature fruits from this particular family, along with many others such as cherries, plums, raspberries, apples, and apricots as well as many others which a number of people have misconceptions about due to unfounded rumors and myths.
