This has always been my view as well, but earlier in the summer I was 
visiting a garden in the Cotswolds and saw the familiar flowers of T. 
pentahyllum twining round something else. I expressed my surprise and was 
told it was hardy there! The garden in question is even higher than we are 
here, so I shall put my plant out for 'hardiness testing' next spring. It 
certainly doesn't deserve precious greenhouse space...
