Is that the plant it came from in the background? Looks kinda like the boxwood we had in the yard when i was a kid...it had dark berries sometimes.

If it's from the plant in the background, I agree that it's some kind of Carissa, but they may be overripe. Usually they are more reddish when at their peak.

cocoplum

I agree, Cocoplum, Chrysobalanus icaco. It is a SoFL native.

There you go, then. If Eric says, it is. :)

Thank you everyone, I will let her know. By the way, is it edible?

You betcha!

Looks like cocoplum to me as well. I had some growing & while the fruit is edible, mine was insipid - barely even sweet.
