This one is a 8-9 footer I installed in my neighborhood
I hope it makes it for you. It looks like the leaves are closed up a little. Are they freeze-dried or do they look good up close? That would be really cool if they survived unprotected.
Looks beat up, but I believe it will out grow the damage rather quickly. I think you may have found a good source for hardy windmills.
The leaves were curled up. They are mirroring my Rhododendron's leaves.
