I have a ton of berries growing in our woods. The berries are ripe right now and appear to be blueberries. The bushes height range from 1-4 feet tall. The thing that throws me off is that some berries on bushes right next to the other are almost black in color. The leaves of both bushes look the same. Both berries the blue colored and dark almost black colored taste blueberry like but are very seedy. I've surfed the internet and they look like blueberry bushes. How can I find out. I'm in MA so would they be ripe now? Are they bilberries?
