The Polly White or Polly peach will give you reliable crops of tasty, sweet, medium-sized, white-fleshed fruit.  It is hardy to 20 degrees below zero.  It is self-fruitful so a pollinator is not needed.  It blooms beginning in late April.  It's mature height is 18-20 feet.  You can harvest these great peaches in early August. 

This would be a good peach for smoothies and desserts as well as eaten fresh.  I remember going to my aunt's farm and fruit orchard in Iowa, and by the way Iowa is where this peach was developed, and picking fresh peaches off the tree.  The sugary sweet juice dripping down my chin and onto my formally clean clothes.  The dogs loved it as they tried to lick the juice spills off my clothes and face.  She did a lot of canning with peaches and the made the best pies, jams and desserts that I had ever tasted.  Unfortunately, we didn't get to visit often but those visits were memorable visits!
