I had not too bad of damage, mostly the unknown got hit the hardest, the negrone lost any leaves it had coming out but the terminal bud is still green with no spots, the black maderia lost the top most leaves but the breba on the bottom is safe and half of one panachee lost expanded leaves so I would say I got lucky for now but next year a greenhouse would help. The VdB about 2 feet from the negrone did have a damaged leaf only a single one, all the brebas are fine so I was very excited to see it is fairly resistant to frost, it is the only one that doesn't have distorted leaves from the cold temperatures, only distorted leaves from fmv, still this will be the next one in the ground.
