Seems Worsleya do so well in Aussie, the top growers of this plant are from Australia! If you need any advice Ron Redding would be a great person to ask as well as Glenn Callcott!
I know people who grow this plant from Canada to Switzerland, Northern US and HOT Mexico to California! Some are growing this plant in blonde sphagnum moss with GREAT success, I don't think it's as difficult as a plant as once thought.
Good luck!
