Bet it isn't up here, pal!!
I'm very pleased that the RHS have introduced a new hardiness guide - will the plant labelling companies use it?? 3 guesses - 1 will do!
I have certainly seen online plants being described as hardy in mild parts of the UK...when you look into it (not on the site selling them) then sheltered, frost free and winter dry is the only way to keep them alive. That rules out everywhere (and yes I know parts of Ireland and the Scillies are very mild but they are also very wet and windy).
