What is that?
Looks like blueberries! Pancakes, muffins or pie? Or freeze and eat on top of cereal. What ever floats your boat!
Look at the leaves, not blueberry leaves. Is it barberry? Mahonia? Is it freeze tolerant at your place?
Looks like mahonia to me.
Mahonia.....no pie! gets a little burnt in the winter, but has been there for years....
