Last weekend I went to an open house/garden. Its is pretty interessting that it is possible to have an exotic garden in our climate too. Of course you have to invest some time and work to get your own oasis.
During wintertime the planted-in palm- and banana-trees will be covered up and those exotic plants in a pot will be carried into a greenhouse. So for sure next year I will get me 5 ft. palmtree and hopefully I will have a green thumb with it.
