No I don't think osage is edible. They are rock hard and don't smell to
good. But I was also thinking about persimmon. It is a member of the
genus Diospyros. The genus contains about 500 species many of which
produce the fruit called persimmon in English.  About 12 species produce
black heart wood and are called ebony. D. kaki is the Japanese persimmon
which is widely planted in the southern US but it dosen't produce black
wood. It is great for woodworking. I can't remember about the fruit
structure. It being 30 years since I ate one. I think it has several
seeds. I can't think of a wood with berry like fruit.
