On a recent South Jersey Wildlife Garden Tour we explored Shoshana's garden, a homeowner in Cumberland County NJ. She greeted us with exotic Pawpaw fruits (Asimina triloba). I had only seen them in a garden catalog years ago and didn't know you could grow the trees in New Jersey.
According to Shoshana, "They sucker beautifully," meaning they can form a grove. Pawpaw trees produce the largest fruits native to North America. Typical to most fruits, pawpaw fruit is an excellent source of Vitamin C. Kentucky State University researchers report that nutritionally, pawpaw fruit has about as much dietary fiber as an apple and is most similar in composition to bananas. Rutgers New Jersey Agriculture Experiment Station reports that it's rare to see pawpaw fruit in markets and come to think of it, I never have.
Scientific studies in 1980's and 1990's by researchers at Purdue University discovered compounds from pawpaw bark extracts may have beneficial effects on killing cancer cells. Since then there has not been enough scientific evidence to make claims supporting the effectiveness of pawpaw for any condition.
