I moved into a new home in CO in the last 6 months, and just noticed some berry bushes in my front yard. They seem to be either blueberries, huckleberries, or possibly bilberries. But I'm hoping someone can help me better identify these berries, and confirm if they are indeed edible.
The berries appear to start our red, and then their color darkens to purple and then to blue as they ripen. The bushes themselves are about 4-5 ft tall.
