These small peach trees are hardy to zone 5a, grow to about 15 ft tall and 6 ft wide. If the blossoms aren't damaged by late frost, the crop is often heavy enough to break branches (thinning advised). 
 
White Iowa peaches are white fleshed, sweet and juicy, and about the size of a golf ball. Great for canning, freezing and eating fresh. Fruit comes off the pit easily.
