Penstemon unknown

This is similar to the one given to me in Cornwall, at a cottage we stayed in. The person who owned the cottage gave me the cuttings after i admired it, that was ten years ago.. still growing strong. Just take a few cuttings .. just in case.

I bought the 'blue collection' from Hayloft this spring, and all but one is growing really well. I shan't know the names until they flower, but one of them might be this one.
