Everyone is missing the obvious choice, and I would have, too, if I hadn't seen it in person.
This is Negronne, grown from cuttings of my tree, about 90 miles north of me. Most of my leaves have three lobes, and some with 5 (usually 3 with two smaller lobes, like this one has), but I have never seen 7 lobes on my tree.
Ain't frigs fun?
