As a landscape designer and grower, I was always looking for the next cool variety of plant or perhaps enticing a plant that does not belong in your climate zone to stay and visit for a while. I went to a lecture by some landscape designers in Long Island and they wrote a book about putting Tropical Plants into the cool climates of New England. So I started integrating Cannas, Elephant Ears, Banana Plants and more into my Cape Cod gardens. Obviously they would not winter over outside so they had to be dug and stored in a greenhouse or basement.
Here are a few pictures of some of the gardens I planted in this manner.
When I moved to Florida, many of the Tropical plants that I found, I was already familiar with so the transition to Florida planting was a breeze.
