The Red Saucer Peach tree gets its nickname from the shape the peaches take, which is flat and round with the center sunken in. This clinging peach tree produces a medium to large size peach that is very sweet with a slight hint of almond. The Donut Peach tree is self-fertile and the fruit can be harvested anywhere between July - August. You can grow the Donut Peach tree in many areas since they are cold hardy down to approximately -15 degrees farenheit. (USDA Zones 5-10)
