Nic,
I am close to you and may have an air layer of makadonia dark for you as well ( will have to check). I believe it is a Mt. Etna, and among one of my earlier producing ones, along with Unk Dahrouge Lebanese, and bisirri #3, which have all started producing. All other Mt. Etnas are getting close, but the aforementioned ones are 7-10 days ahead, at least. It would be a good one for your project, I think. It suffered very minimal dieback this past year in ground ( caveat: it was 3 years old and this past winter was mild).
Frank,
