I’ve seen these gorgeous purple beauties growing in many a private garden over the years, particularly in the South-West, but I noticed several of them this month (August 2008) for the first time ever, blooming quite happily in a few sunlit, out of the way places not far from the North Cornwall coast path….and a significant distance from any cultivated gardens! Of course, there’s always the possibility that someone actually planted them there, but I’d say that it’s unlikely in view of the fact that all but one of the locations was virtually inaccessible!
