Yes, I have been bringing my huge vine in for about 4 years now.
I keep it in the basement by the sliding glass doors - it gets the setting western sun. We rarely turn the heater on down there, but it does quite well.
The ONLY problem I have, is that one of our cats just LOVES to eat the leaves and it is usually bare by the time I take it back outside in the spring
!!! Last year I cut the vines back dramatically in about February, and it grew like gangbusters outside this past summer.
Don is bringing mine indoors today. I'll try and take a picture later.
I've tried taking many many cuttings from this plant, but so far have only managed to get 1 to grow - and that was just pure luck.
By the way... what color are your flowers
