When I purchased my two elderberry bushes from Audubon Society about 4 years ago, they were described as "Woodpecker Alley Shrubs", and the word "elderberry" was in the description, so I decided to try them. It took them 4 years to produce berries, but last year they were absolutely loaded with berries. I'm surprised the birds don't get them, but my daughter picked them and made elderberry syrup which was very tasty. They are loaded with berries again this year, not ripe yet. They have grown to about 12' tall each year and are very pretty for their foliage. I'm not sure which variety they are, but I think S.nigra?
