Our elderberry bushes bloomed in early May this year. As these bushes gain in maturity, they continue to get larger and produce more bracts of flowers.
This year was the best yet.
The flowers ripened into small purple berries in late June and early July. However, only a small percentage of the flowers became berries. I attribute this condition to poor pollination. I don't think the poor pollination was attibutable to a lack of bees and/or moths because we have plenty of pollinators flying around. Elderberries require cross pollination, and I have planted two types of elderberries: Johns and Adams. I suspect that the Adams, which is placed well behind the Johns in the shade, may not be getting the attention of the pollinators that is needed for cross pollination, but this is speculation on my part. I may try to plant another Adams nearby to see if this will rectify the issue.
Here is what these partially pollinated berry bracts look like:
