Yeah the wet cold Winter can do in some passiflora mollissima is not to hard to find to start again but P. ligularis is a little harder to find sometimes she looks happy now! I have one outside but die's back to ground then comes back so far just can't get it up big enough to survive. Mine was growing under passifloria edulis so was protected a bit.
