Good luck with them Alastair, I grew them from seed last year in normal compost. They took an age to germinate after in fridge/out fridge, inside/outside treatment. In the end I just left them outside and finally up they popped!
I have a few still alive in pots from my last place, they are lovely plants and although I found them fidley to grow, they look lovely and the butterflies and insects adore them!
ps- Didn't realise you can take root cuttings from them
