Answer: What you describe could be frost damage; time will tell. I wouldn't dig the plant up quite yet. If a late frost nipped the new growth, the roots should send out new shoots in a few weeks. I'm not sure I can solve the mystery of why only one plant was affected, except to say that all gardens have micro-climates and some plants within a few feet of one another can escape frost damage while others are totally overcome. I'd wait on the vine - you wouldn't want to dig it up if it was really putting all its effort into resprouting. If you see no signs of life in 2-3 weeks, I'd replace it with a new silver lace vine. Best wishes with your garden!
