Hi

I'm going to be buying a Passion vine and need to know which type to go for that would survive cold weather.

It'll be kept in the wheelhouse of a boat which is un-insulated, so it will be protected from the wind but the tempreture will be pretty much the same as outdoors, which is pretty chilly most of the time. I'm guessing during Summer it'd have almost a greenhouse affect for the plant, if we manage to have any Summer that is.

Anyone know of any good types of vines that are pretty hardcore through cold weather but still have the colourful scented flowers too?

Thanks in advance!
