Pawpaw are Native to North America and are Very Cold Hardy Fruit Trees. They Grow Wild in 26 States, Mostly East of the Mississippi. It's Probably Best Known and Loved in the Mountain South, where Stands of Trees Produce Fruit that Weighs between 5 and 16 Ounces, Making it the Largest Tree Fruit in North America. In Recent Years, More Pawpaw Trees have been Cultivated, but, for Most Fans of the Fruit, Part of the Pleasure is in the Thrill of the Hunt for them in the Wild. According to Kentucky State University's Cooperative Extension Program, Pawpaw Fruit has a Sky High in Vitamin C, Magnesium, Iron, Copper, and Manganese. They are Also a Good Source of Potassium and Several Essential Amino Acids, and they Also Contain Significant amounts of Riboflavin, Niacin, Calcium, Phosphorus, and Zinc. Pawpaw Fruit Contains these Nutrients in Amounts that are Generally about the Same as or Greater than those Found in Bananas, Apples, or Oranges. Though the Pawpaw’s only near Relatives are Tropical, and Paw Paws Look like Mangos and Taste like Bananas, they are Not Tropical but are Native to Most All of the Eastern United States and Even in Parts of Canada. The Pawpaw Grows Best in Areas with Hot Summers and Cold Winters (USDA Plant Hardiness Zones 5 to 8). It is Cold Hardy and Relatively Pest-Free, and it's Tolerance to Shade Makes it Suitable for Intercropping with Certain other Trees. Pawpaw Trees will Grow from 12 to 25 Feet Tall and Should be Spaced 8 to 15 Feet Apart.
