Pawpaw can work here, with caveats. Native and genuinely common in central Indiana bottomlands, creek corridors and shady rich woods, where it forms dense clonal thickets in the understory; Purdue extension calls it the Indiana banana. It is now also planted on purpose for fruit, which requires two genetically different trees for cross-pollination — a detail worth raising before anyone removes the second tree in a pair.
Fruit is the entire debris story. Ripe pawpaws drop in a concentrated window from late August into September, bruise on impact and rot into a sweet mush on the ground that pulls in raccoons, opossums, deer and yellowjackets; the large leaves turn clear yellow and drop in fall, but nobody has ever called about pawpaw leaves.
The defining feature is a brittle, carrot-like taproot that drives deep before the top gets any size, which is why wild-dug pawpaws almost never survive a move and why bare-root stock fails at close to 100 percent — container stock is the only reliable option. Laterals sucker freely, so what looks like a stand of separate small trees is usually one clone sharing a root system, and severed suckers die because they never built independent roots.
