It’s paw paw season! Paw paws (Asimina triloba) are native trees that bear fruit in August, September, and October. Fruit of cultivated trees look very similar to mangos—green, kidney-shaped, and about 6 inches long and 3 inches wide. They have a variety of common names such as Indiana banana, poor man’s banana, and bandango. When cut in half, the interior reveals a yellow, custard-like pulp with two rows of large seeds. Paw paws can weigh from ½ to 1 pound. Technically a berry, they are the largest North American edible fruit. Paw paws taste like a cross between a banana and a mango with a splash of pineapple. They can be eaten raw or used in ice cream, pudding, smoothies, butter (such as apple butter), baked goods like cookies and pies, and even beer, brandy, and wine!
From Florida to Texas, north to New York, and west to Michigan, Illinois, Iowa, and Nebraska, paw paws are native to 26 states and grow as understory trees in hardwood forests near streams and rivers. In the wild, the trees grow to 15 to 30 feet and sucker, creating colonies. Reminiscent of cucumber magnolias, they have foot-long, dark green leaves. Unlike other fruit trees, paw paw trees are not subject to a high level of pests and diseases.
Paw Paws in American History and Folklore
Paw paw trees are part of American history and folklore. Jamestown colonists wrote about them in the 1600s. John Lawson, an Englishman, described them in his travels in the Carolinas in the 1700s. Danielle Boone enjoyed eating them. Members of the Lewis and Clark expedition ate paw paws for pleasure as well as sustenance. George Washington grew paw paw trees at Mount Vernon and ate the fruit as dessert. Thomas Jefferson grew them and sent seeds to his colleagues in Europe. William Bartram, a naturalist, described the trees in Bartram’s Travels. His father, John Bartram, a botanist, sent seeds to Europe. During the Civil War, soldiers as well as African American slaves collected the fruit in the wild to supplement their meager diets. There is even a popular folk song called “Way Down Yonder in the Paw Paw Patch” about collecting ripe paws paws from the ground and putting them in a basket.
Finding Paw Paw Trees and Fruit
Currently, Washington DC residents can see paw paw trees in the wild along the C&O Canal and Potomac River and as native plant representatives in public gardens. There are paw paw trees at the Smithsonian Pollinator Garden, next to the National Museum of Natural History, and at the U.S. Botanic Garden’s newly renovated Bartholdi Park and their National Garden’s Regional Garden of Mid-Atlantic Native Plants.
Although paw paws are part of American heritage, you may not find them in grocery stores. When the fruit is ripe enough to eat, it drops to the ground and is highly perishable. The thin skin bruises easily, discoloring to black. Paw paws are best eaten immediately or preserved by removing and freezing the pulp. You may find them at local farmers markets in peak season and you will definitely find them at paw paw events across the country in the fall.
Growing Paw Paws in the Home Landscape
“There is a paw paw renaissance now,” said Michael Judd, owner of Ecologia, an edible and ecological landscaping service in Frederick, MD. Author of Edible Landscape with a Permaculture Twist and For the Love of Paw Paws, Michael hosts an annual paw paw festival which will be on September 21 this year at LongCreek Homestead. “I call the paw paw an edible landscape all-stars because the tree is very attractive, low maintenance, and very fruitful.”
As native, hardy trees, paw paws can be grown in typical suburban plots. “Paw paws grow easily here,” said Michael. “This is paw paw country.” Although they are not self-fertile, that is, there must be two trees to cross pollinate to produce fruit, one can trim the trees to fit in residential properties. Michael recommends growing the trees in full sun, 10 to 12 feet apart, and cutting the central leader back to keep the trees at 8 feet. This shorten stature also makes them easier to harvest the fruit. Therefore, homeowners could have two 8-foot trees in the yard producing 50 pounds of fruit each year. If full sun is not possible, they can grow in part shade but will produce less fruit.
Michael recommends purchasing either a grafted tree, a select seedling, or a specific cultivar. Starting from seed takes years to produce fruit. Also starting from a wild paw paw seed will result in less than desirable fruit. The taste of wild paw paws varies plus the fruit is small with a poor pulp to seed ratio. Breeders spend years selecting desirable characteristics such as large fruit, a high pulp to seed ratio (more pulp, less seed), and good flavor.
You can’t go wrong planting paw paws. They are native, deer resistant trees that provide fruit and pretty yellow fall color. “Paw paw trees are very ornamental, they have a beautiful pyramidal shape,” explained Michael. “The leaves turn to a beautiful yellow golden color in the fall and when the leaves drop they reveal a tree with nice architecture in the winter.”
