Sorry, I don't know. If you don't get a reply here, clip a leaf and take to nursery! Maybe the armadillos collect plant tags.

Thank you! Gorgeous plant. Thinking of adding a few on the north side of our house.

Thank you James Patrick for this thread. What a beautiful specimen, probably because it receives abundant sunshine. Yesterday I traveled to a 60 acre public garden in Delaware. While the gardens were full of rhodies and azaleas they were all of Asian origin. Here is best ML specimen on the property which is around by the employees parking lot. On my way to Delaware and on my return I noticed rhodies, azaleas, hydrangeas, viburnums, mockorange and lots of knockout roses all in full glory. The only place that I ever see ML of any significance is undisturbed understory, stream banks and woodland edges. OP's pic is a true gem.

Not sure which leaves are which. The walnut-like leaves apparently are a different plant. If you could snip off a full leaf & lay it on a white background for a close-up pic, that would help.
