The only one I can think of is Clematis montana 'Marjorie' which is described as 'salmon pink' (was more salmon than pink in my garden) but probably will not be hardy for you. To my knowledge, there are no LFH's that fit this coloring.

'Pink Fantasy' has a slight peach/salmon cast to the blooms especially as they open but it is slight. I bought her to go with a darker salmon rose. See the bottom photo linked below for what I mean about the color as they open. This is the closest that I've seen to peach/salmon.
