Well, I was posed to ask virtually the same question. I do not grow silver lace vine myself, but the garden I am employed to care for has 2 of them. They have been in place for at least 3 or 4 years. I started working there last summer, when the silver lace vines were beautiful - vigorous and full. This spring, one shows absolutely no sign of life, the other has growth from only one of its many "stalks". I have ordered replacements for them...but my question is, do silver lace vines have a reputation for putting on a glorious show one year and then giving up the ghost the next year?
These vines are in NH where we had a record breaking snow fall, but temps weren't significantly lower than usual.. These vines grow right up the side of a house.
