Canadian Gardening: Tropicals in Canada, 1 by eastjack

How many Canadian gardeners try growing tropical plants? I have an unheated stand alone greenhouse and an unheated sun room attached to the house. So far I have only tried growing Mandevilla. They do very well in the sun room during the summer as they can stand the high temperature that the room sometimes gets to. As soon as the temperature drops to freezing in there I cut them back and bring then in the house for the winter. It would be interesting to hear what varieties other Canadians have had success with under similar conditions.
