A small cluster of these small trees (large bushes?) are growing on my
property.
They were pretty non-descript until the fall when they suddenly became
covered with
very small blue berries. Anyone know what kind of tree this is? I'm in Zone
5 (connecticut)

Nothing seems to be eating the berries, so I'm assuming they're toxic.

There's a picture at
