On holiday in Scotland a few years ago I saw a truly awesome climber with masses of smallish pink flowers, and I'd love something like that for my garden. I don't know what it was - Google pointed me to bougainvilleas but I don't think they are hardy?
The wall I've got in mind is a south east facing one, so pretty sunny - it's south Germany so the winters are -10 at worst, and summers are long and warm.
Does anyone have any suggestions?
