Just wanted to share that I do grow different exotics in Sydney on Cape Breton Island. Here is the only pic I can find right now of one of my Waggy's. I do grow Musa Basjoo, Fatsia Japonica, Moso Bamboo, and three variants of Trachycarpus also. (Wagnerianus, Fortunei, and the Hybrid cross between them both).
As of winter protection, all I do is put 3 rebar in ground surrounding the palms and wrap burlap around the bars. No heat, and nothing wrapped around the palm physically and just throw some pine bark nuggets around the trunk. I was hoping to have them unwrapped by now, but with this out of the blue late storm we had last week, there is approx a one foot drift around them and I don't want to walk through it
So looks like I'll have to wait till the beginning of April to unwrap.
Here is the waggy in my backyard:
