what berry bush has red berries that turn blue in groups of three and eye shaped oval green leaves?

Question

The berries taste like blueberries but are much seedier. Unripe berries are red. Leaves of the  tallish bush look similar to those on a wild blueberry bush but a little larger. They are eye-shaped ovals, green in colour. The bush has tall woody stalks.

The bushes were found in the Georgian Bay area of Ontario on a small island. They were growing at  waters edge and continuing about six or seven feet toward the centre of the island.

Answer 1

I would not eat them until you know exactly what they are.............take a branch to a grower and ask him...............it could be wild blueberries.............they are much smaller than regular ones............but no seeds in blueberries............it could be currents that are berrys with seeds 2 kinds.............there are also berries that are poisonious..........I would investigate further before eating them.
