I bought this in a pot early spring and put it at the base of a scrawny dogwood that I have a hook hanging from a branch that held the hummingbird feeder. I lost the plant label....

It was so pretty all summer with the vines growing up beside the hummingbird feeder. I can't help but think the birds were drawn to the feeder location by the flowers.

I need to bring it in for winter. Any suggestions? Will it flower indoors? I have a heated sunroom, pretty good light.
