I'm new to this forum and I really love the tropical gardens. However, I'm zone 5 and in the heavy snowbelt area and I'm wondering if there are any plants that look tropical yet don't need to come in for the winter. My dad used to grow cannas but they had to be brought in for the winter. I like the look of the very large leafy plants but other than some very large leafed hosta varieties I don't know of any plants that I could use here. Any ideas?
