So glad to have 'discovered' your work, John. Welcome. I'm new on here, but an elder in many things. I hope we can all be motivated to grow our own; have seen the local wild elderberries progressively plundered by people who are coming into the new/old knowledge- last year could find very little to ethically harvest. Gratified that some trees were tall enough for birds to harvest, and our own trees are beginning to be really productive! I'm curious about your take on the red berried elder of the Pacific coast, having seen varying opinions on toxicity.
