Hey all.. I've created and read several threads about the most northern palm trees, but what about the most southerly ones? The most southerly Phoenix Canariensis could probably be grown or is already in Invercargill, NZ (46 degrees south) which is zone 9 (I've personally seen them growing in Melbourne, Australia at 37 degrees south but I'm sure they could be cultivated much further south than this). The most southerly Trachycarpus Fortunei could probably be grown or is already in Punta Arenas, Chile (53 degrees south - Zone 8). What are your thoughts?
