How to identify a pawpaw tree
A pawpaw (Asimina triloba) is easiest to recognize by four things together: large, drooping, tropical-looking leaves, a small understory tree that grows in suckering patches, deep maroon flowers in early spring, and green, mango-shaped fruit hanging in clusters in early fall. Learn those and you will spot pawpaws for the rest of your life.
The five checks
No single feature is foolproof, but the pawpaw stacks several unusual traits that, together, rule out everything else in the eastern woods. Run through these in order.
- Look at the leaves. Pawpaw leaves are large, 6 to 12 inches long, broadest past the middle (obovate), and hang down so a pawpaw in the understory has a distinctly tropical, drooping look. They are simple, alternate, and turn clear yellow in fall. Crushed, they give off a faint, slightly unpleasant green smell.
- Check the size and growth habit. It is a small tree, usually 15 to 25 feet, growing in the shade beneath taller hardwoods. It suckers from the roots, so pawpaws often appear as a patch of clones rather than one trunk. A dense colony of identical small trees is a strong pawpaw sign.
- Look for maroon flowers in early spring. Before the leaves fully expand, pawpaw opens nodding, cup-shaped flowers about 1 to 2 inches across with six petals in a deep maroon or purple-brown. Nothing else in the eastern woods flowers quite like it, so a flowering pawpaw is unmistakable.
- Look for clustered green fruit in late summer. From late August into October, look for green, oblong, mango or kidney shaped fruit hanging in small clusters. As it ripens the skin yellows and speckles. The large fruit in clusters on a small understory tree is the clearest tell of all.
- Confirm the habitat. Pawpaws favor moist, rich bottomland and shaded slopes across the eastern United States. A tropical-looking, drooping-leaved small tree in that setting, especially in a patch, is almost certainly a pawpaw.
Leaves
The leaves are the everyday giveaway. They are big, 6 to 12 inches long, simple, and arranged alternately along the twig, broadest past the middle and tapering to a point. Crucially, they droop, which gives a shaded pawpaw an almost tropical, wilted look even when the tree is perfectly healthy. In autumn they turn a soft, clear yellow. Crush one and you get a faint, slightly rank green smell that many foragers use as confirmation.
Form, bark, and the patch habit
Pawpaw is a small tree, usually 15 to 25 feet, that lives in the shade of taller oaks, maples, and beeches. Its bark is thin, smooth, and gray-brown, sometimes lightly blotched, roughening a little with age. The habit is the useful part: pawpaw spreads by root suckers, so it commonly grows as a colony of genetically identical clones, the pawpaw patch of the old folk song. A thicket of matching small trees under a hardwood canopy is a strong clue.
Flowers and fruit: the sure tells
In early spring, before the leaves fully expand, pawpaw hangs nodding, cup-shaped flowers about 1 to 2 inches across, with six petals in a rich maroon to purple-brown. They are pollinated by flies and beetles rather than bees, and nothing else in the region flowers quite like them.
By late August into October, those flowers become fruit: green, oblong, roughly mango or kidney shaped, hanging in small clusters and yellowing as they ripen. Large green fruit in clusters on a small shade-loving tree is the single most conclusive pawpaw sign. See harvesting pawpaws for how to tell the fruit is ripe.
Lookalikes and how to rule them out
Because the leaves are so large, a young pawpaw is occasionally mistaken for another big-leaved understory plant such as umbrella magnolia. The difference is arrangement: magnolia leaves cluster in whorls at the ends of the branches, while pawpaw leaves are spread out along the twig and hang down. When in doubt, wait for the two features no lookalike shares, the maroon spring flower and the clustered green fruit, and you will have your answer.
Common questions
How do you identify a pawpaw tree?
By four things together: large drooping leaves 6 to 12 inches long, a small understory tree that grows in suckering patches, maroon six-petaled flowers in early spring, and green mango-shaped fruit in clusters in early fall. Any one can be mistaken; all four together are unmistakable.
What do pawpaw leaves look like?
Large, simple, and alternate, 6 to 12 inches long and widest beyond the middle, tapering to the tip. They droop from the twigs, giving the tree a tropical look, and turn clear yellow in autumn. Crushed, they smell faintly green and unpleasant.
What does pawpaw bark look like?
Thin, smooth, and gray to brown on young trees, sometimes with pale blotches, becoming slightly rougher and warty with age. Bark alone is not a reliable identifier, so use it with the leaves, flowers, and fruit.
What can be mistaken for a pawpaw?
Young pawpaws are sometimes confused with other large-leaved understory plants such as umbrella magnolia, but magnolia leaves cluster at the branch tips while pawpaw leaves are spaced along the twig and droop. The maroon spring flower and the clustered green fruit are the reliable tells that no lookalike shares.
When is the easiest time to identify a pawpaw?
Early spring, when the maroon flowers appear before the leaves, and early fall, when the green fruit hangs in clusters. Both are features nothing else in the eastern woods copies. In summer, rely on the large drooping leaves and the suckering, patch-forming habit.
