Asimina triloba, also known as the Pawpaw tree, is a flowering tree native to the Southeastern part of the United States.
The tree grows to between 15 and 30 feet (4.5 to 9 m) in height and has a spread of about the same size.

The tree features long, oval leaves of pale green, and dark purple or red flowers; these bloom from April to May in the Northern hemisphere.

After the flowers have passed, yellow-green fruits appear. These are edible and taste somewhat like bananas.

Asimina triloba are generally considered to be easy to care for, and for that reason, they're a popular choice as a statement tree in the yard or for use in a rain garden.
Asimina triloba is often found growing along streams or in the lower regions of wooded areas, so it makes sense that this tree prefers medium to wet soil.
These trees thrive in partial shade, but they will also tolerate full sun or full shade.
Soils that are high in nutrients and that remain moist are the best choice for these trees, but even sandy or clay type soils will still allow the tree to grow well.
The Pawpaw tree is a hardy plant and is not generally susceptible to diseases or parasites.
Asimina triloba reproduces through cross-pollination, but the tree can also be propagated from its root suckers.
Trees that are located near each other and can cross-pollinate tend to produce more fruit.
So if an overabundance of unwanted fruit is an issue, it may be best to keep only one tree in the garden.
