I do plan on putting the passion flower on the south side of the garage, between the west wall of the greenhouse and my double rain barrels. There will be a Caryopteris in front of it. Theoretically, it should be warm enough during the winter (I think) since it's protected on the north and west. If it grows, it can stretch over the GH roof in the summer, giving some shade in there. I tried one there once before but I was probably too impatient to plant it properly. Plus, that would be under the eaves of the garage so will have to watch the watering.
I only have one canna that I grow in a pot. Don't have a lot of sunny spots for it.
