We arrive finally at the trees I don’t know, though there may be a few more I do in later posts in this series. This one seems an ornamental, and it lines some streets in my area. It has very long alternate compound leaves (2’ or more), and the leaflets split in two at their tip, looking like 2 leaves welded into one. This past week or two a few have begun to bloom in large pink flowers. My pics are from several specimens lining a local street.
If we solve it, I’ll research it and do a follow-up post with more info. Thanks for any help!
