American Heritage: Native Paw Paw Trees

Paw paw flowers in the spring

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

Paw paw fruits can be eaten raw

“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, Michael currently is writing a book about paw paws and hosts an annual paw paw festival that will be on September 22 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-f00t 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.

Paw paw trees have a pyramidal shape

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.”

Greenstreet Gardens Sets Up Shop in Belle Haven, Virginia

It’s no mirage–that is a tropical oasis on Richmond Highway. Residents of Belle Haven are noticing a pop of color now that Greenstreet Gardens has moved in.

Ray Greenstreet, owner of Greenstreet Gardens, is leasing the lot at 5905 Richmond Highway, Alexandria, Virginia, as an extension of the Greenstreet Gardens retail operation. Instead of building a new structure, Ray created an open air retail garden center featuring houseplants, perennials, annuals, containers, fertilizer, and gardening tools.

“This location just fell in our lap but it is a great opportunity,” said Ray. Despite the windfall, it took months to get the place into shape for the customers. “This was vacant for a long time, maybe 10 years,” said Ray. “Before we came, it was a VDOT (Virginia Department of Transportation) lot for the Wilson Bridge where they dumped gravel. We had to remove 5 dumpster loads of trash.”

Currently, the cash register is in an open shipping container. The products, from plants to fertilizers, are outside on racks or wooden benches. The fire hydrant on the sidewalk provides the water for the plants, most of which are in full sun.  Although Ray is working to have electricity, lighting is not an issue now with the long day length. Just the inventory alone, lush green foliage and eye-popping flowers, beautifies the neighborhood but Ray intends to enhance the location even more. “We intend to add trees to create a park-like setting,” said Ray. “In the fall we will sell chrysanthemums and pumpkins followed by Christmas trees.” After the holidays, the location will close in January and February and re-open in March.

I visited the corner lot last weekend. A large, tall display of tropical plants in containers marks the entrance to the parking lot, which is quite spacious. There was a wide variety of plants on benches and racks of new plants that had just been delivered. The plants were well watered and healthy and the employees were pleasant and helpful. Because this location is just south of the Beltway on Richmond Highway with plenty of traffic, stop lights, and median strips, I thought it would be difficult to access. It turned out to be easy to get in and out with no problems.  This new location truly provides a new source of greenery to residents on the northern end of Richmond Highway.

A native Marylander, Ray and his wife Stacy started Greenstreet Growers, a greenhouse operation in Lothian, Maryland, in 2000. They then ventured into retail and opened Greenstreet Gardens on 14 acres of their 65-acre farm in Lothian. In 2012, they expanded into Virginia and opened a retail store at 1721 West Braddock Road, Alexandria, which is thriving. Later they opened a smaller store in Del Ray, now closed. The Belle Haven location is the third Virginia location and is open every day of the week from 9:00 am to 5:00 pm. If you are ever in the area, stop by and say hello to our new neighbors!

 

My Podcast Debut on the Vegetable Gardening Show

It is an audio and visual podcast so you can have the pleasure of seeing me talk with him on Show #414: Gardening in the Nation’s Capital for 30 minutes on YouTube or listening to me on Podbean, Stitcher, iTunes, or iHeartRadio.

Mike gardens in New Jersey, manages the Seed of the Month Club, and has authored Vegetable Gardening for the Average Person. We talked about why I started writing gardening articles for magazines and how I designed my website and the services I provide, including the free monthly newsletter. We talked about growing tomatoes, herbs, and potatoes and the gardening challenges we have in common such as minimal space and deer. The podcast was like chatting with the neighbor in the garden, it was a lot of fun. If you have not heard of Mike before, check him out at www.averagepersongardening.com.

Relax in DC’s Renovated and Sustainable Bartholdi Park

The U.S. Botanic Garden (USBG) has completed the renovation of Bartholdi Park. The new garden is a showcase of sustainable gardening. Created in 1932, Bartholdi Park has served as a demonstration garden for more than 80 years. In 2016, a complete renovation started that also provided the opportunity to increase accessibility, showcase the Sustainable SITES Initiative principles in action, and demonstrate USBG’s commitment to sustainability.

Some of the changes will be noticeable to visitors. For example, most of the plants are native to the mid-Atlantic region. There is an expanded collection of edible plants in permanent and seasonal plantings in a new kitchen garden. Some of the large trees and shrubs were retained while others were placed in other locations in DC. There is more signage and more places to sit and relax. The tables and chairs were made from white oaks that had fallen naturally during a storm. There is a bike rack, additional lamps/lighting, and a water fountain. There will be outside activities such as yoga and nature-in-motion walks. Not so obvious to visitors are structural changes such as using permeable paving and rain gardens to capture rainfall, diverting runoff from D.C.’s combined sewer system. The original soil was saved and then added back with additional compost. Flagstones from previous pathways were salvaged to create new paths.

Bartholdi Park has achieved the SITES gold certification for its sustainability strategies. It is the first project in Washington, DC, to be certified under SITES Version 2. Sites is a comprehensive system for designing, developing, and maintaining sustainable land. The Park serves as a model for communities interested in sustainable gardening landscapes that are accessible and enjoyable by the public.

The story of the renovated Park is shared through new signage in the Park. A new Field Journal, an interactive booklet for young visitors, can be picked up free at the U.S. Botanic Garden’s information desk. Tours of the Park and other activities can be found at www.usbg.gov/programs.

The U.S. Botanic Garden is open to the public, free of charge, every day of the year from 10:00 am to 5:00 pm. The conservatory is at 100 Maryland Avenue SW on the southwest side of the U.S. Capitol. The Bartholdi Park is across the street. All of these photos are courtesy of USBG.

This Week is National Pollinator Week: Learn How to Support Vital Pollinators

This week, June 18 to 24, 2018, is National Pollinator Week. Organizations across the country will host pollinator awareness events.  In Washington DC there are several events this week. Also, you can participate in the Million Pollinator Garden Challenge by making your garden pollinator friendly and registering your garden at the site (free). I just registered my Virginia garden, a typical suburban home, for the Million Pollinator Garden Challenge.

For National Pollinator Week in 2016, I featured an herb a day that attracts pollinators. Marjoram, cilantro, dill, sage, chives, basil and thyme are common culinary herbs that when left to flower will attract bees and butterflies. Day seven, marjoram, provides links to the herbs as well as other pollinator related resources and organizations.

This year I am focusing on a different group of plants that attract pollinators, see my article tomorrow on pegplant.com.
