Peach trees (Prunus persica), is a fruit tree of the rose family (Rosaceae), grown throughout the warmer temperate regions of both the Northern and Southern hemispheres.  Peaches are the pitted fruits that are born from this tree.  There are hundreds of varieties of peaches, but they all have a velvety, easily peeled skin, and range in flavor from light and sweet, to more tart and acidic.
