Some peach trees have attractive purple foliage which can add a hint of color to any landscape while also offering fruit. The most common variety of the purple leaf peach tree is the “Bonfire,” a dwarf purple leaf peach tree which is very hardy. The fruit of this tree is bland when uncooked, but is good for making preserves or pies. Purple leaf peach trees require the same types of care as green leaf peach trees. This means that they require a high standard of care in terms of pruning, watering, feeding, and treating for pests and diseases.
