hau Ryan, the fruit serves two purposes to the tree, if the seed needs to pass through a gut system the fruit is the enticement for those animals whose gut the seed needs to pass through, the animal gets some food and the seed gets the acid bath it needs to sprout in the spring.
The fruit can ferment and decay, providing nutrients to the soil that surrounds the seed, these nutrients are thus available for the seed when it sprouts, giving it a better chance at thriving.
Regarding pawpaw trees, The seeds of the pawpaw are designed to over winter in the soil, in nature it can take up to 18 months (two winters) for the seeds to germinate.
The newly sprouted seeds will die if they are not under a canopy and protected from the sun for the first two years. This makes them an understory, secondary tree in the world of succession.
Out in the natural world pawpaw trees are tall, reaching for the sun once they have grown up for around 5 years, the sun is what activates their flowering and fruiting cycles.
The flower of the pawpaw is designed to be pollinated by flies, this means the "nectar" is stinky, stinky, stinky. Many people say they smell like rotten meat, which is perfect if you are attracting flies to pollinate you.
Zone 5 is pretty much the northernmost you will find pawpaw trees growing in the natural world.
pawpaw seeds are meant to go through freeze/ thaw cycles in order to be able to germinate, they are noted to be notoriously difficult to consistently be germinated in controlled conditions like humans do.
This is a tree that needs quite a lot of water in a consistent manner, that is why in the wild you find them along streams and lakes.
