This is my first post so I hope that I am doing it right.

The other day I was walking on the Georgia Tech campus in Atlanta and I saw someone picking berries from a tree/bush. I asked him what they were and he said that they are related to blueberries and native to the south. Unfortunately I could not for the life of me understand what he called them even after asking him to repeat it three times (maybe because he was eating them as we were talking). I didn't want to annoy the guy so I just let it go.

Can somebody help identify this plant? The berries look and taste very similar to the blueberries I'd buy in a store, though the skin was a bit thicker.

Thanks.
