4/ Diospyros virginiana, American persimmon tree

(Sorry for underwhelming pics.) 

Fruit is only ripe when it falls to the ground and is very soft. You can set up a net to catch them. Firm or picked off a tree, they are very astringent. Ripe, they taste like dates and honey. Expect to fruit between 4-9 years after germination. Mostly dioecious but can easily be trunk-fused.
