No, you probably ought not to, and they are bitter anyway. Birds love them which is the main reason I have planted them.
They are known to like damp habitats or stream edges, but they grow well, and spread, almost anywhere. They like sun. I have found them very easy to grow, and highly productive of fruit in Sept/Oct.
What are they good for? Jam and pies. I have never had Elderberry Wine, and most likely neither have you. Why bother?
People use their flowers for flavoring things.
