Here's a comment on paw paws from yesteryear -

Fruit is quite edible, ..Matter of fact: chilled fruit was a dessert favorite of George Washington. Ripens in late Aug, early Sept. Has a sweet custard-ish flavor similar to banana, mango, & cantaloupe. Unfortunately, it has a very short shelf-life. I believe it is North America's largest indigenous edible fruit.
Fruits should manifest in tree's 6th or 7th year.
Native to eastern North America and the Midwest.
It is a patch-forming (clonal) understory tree found in well drained, deep, fertile bottomland and hilly upland habitats.
Young trees are susceptible to sun damage the first 2 years. To remedy that I planted Kong Sunflowers in the same area I planted 2 trees. These sunflowers grow so tall so fast, they performed an admiral job of shade protection. Being self seeders, the sunflowers returned to fulfill said duty the following year.
It's been 6 years and I'm still waiting...Flowered and fruited years 7 and 8. (Updated fall 2013).
Another positive about the Paw Paw is that it is the exclusive food source for the larvae of the Zebra Swallowtail butterfly. By consuming paw paw the butterflies ingest a chemical that makes them unpalatable to birds and other predators.
My two were planted in an area that received sun most of the day, which is a factor unhealthy to grow paw paws in. To overcome that problem I planted the giant sunflower Kong which grew swiftly to provide shade for the new paw paws. Said sunflower self seeded the area for years providing the necessary relief from the sun.
These days I sometimes almost regret planting those trees because they try to establish a colony by dropping a lot of seed bearing fruit that subsequently germinates without fail. They also send up new trees from underground runners; it can be a pretty aggressive
plant.
The only time I've ever seen a zebra swallowtail BF was when those trees were growing up. Seeing that zebras elevated that day to Signature Status.
The flower can be quite the visual delight (in spite of it's disreputable odor) blooming early in the spring on bare limbs. Here's one of my favorite pics related to gardening -
