Thanks for the information Laura. I will try to get a leaf closeup this coming weekend and the bush should be more mature as well. Sounds worth saving, so far.

I can’t see the leaves details clear enough to be certain, and could only speculating this might be a type of elderberry shrubs (Sambucus)? According to sources, it is a food sources for bees, birds & butterflies. If this is elderberry, I can’t tell which one this is. Check out these links for more information.
