You don't often associate Dogwood trees with berries. One reason is that only mature dogwood trees (15+ years) produce enough berries to get noticed. Another is that the immature berries are green and get lost in the foliage, while the mature berries turn red about the same time the leaves do - so they're lost again. Plus, birds often get to them first.
However, they can add a hit of red to the fall garden. This berry cluster is on a Cornus florida or Flowering Dogwood, and they're just about peak.
