Not gonna be hardy for you in the ground. Check out this old GW thread for overwintering and propagation tips.

Here is a link that might be useful: Propagating corkscrew vine

Thanks for that link, I had read it before but because some may have had other successes, or failures... I reposted again.

I never did receive a seed pod on my vine this year and I "know" it is not hardy in my zone, but one could hope. It would be so difficult to dig up a section of this beautiful vine, so I have not done that yet. I may attempt this on the weekend as temps seem above freezing.

I did take multiple cutting at a node and placed them in water for starting. I also bought two new plants on Ebay that arrived promptly and in beautiful shape. One is actually about to bloom!

I have learned my lesson and these two new plants will be kept in large planters and trellised in the warmer months so I don't worry about these beauties again.

So fingers crossed that I root many new plants. In the mean time and with much wishful thinking and hope, I mulched hard the bases of my beautiful vines outside and will also lay fabric mulching cloth over top...then pray we have an easy winter hear in Princeton, NJ.

Thanks again!

I must say I admire your optimism! Attempting to overwinter in the ground, even with protection, a plant that is at least 3 zones above you in hardiness will definitely be a challenge. Good luck!
