if its in a sheltered enough position it will be ok if mulched deeply in the autumn. the top foliage would die back every autumn.

Many thanks SBG I have the very spot.

Thankyou

Also depends on exactly which species it is--most are frost tender tropicals.

As Tugbrethil said, it depends on what species it is. If it's Passiflora-caerulea (Blue Passinflower), and these are the most common passion vines sold in garden centres and the most hardy, then it should survive outside in a sheltered area.

Take a cutting or two for insurance in case it doesn't.

Hi Kath, I live in a pretty exposed area, and I grew Passilora caerulea for several years until we had those 2 very cold winters, the second 1 finished it off, but it did get down to minus 22c, if you plant them 2 or 3 inches lower than they are in the pot, and we get an average winter, if the top growth gets killed of, it should regrow from below soil level, { I had 6 rooted cuttings, but let them in a cold greenhouse, so lost those as well}, Derek.

I have 2 in large pots in west lothian and they do well .
