Well I am glad I am not alone in finding the scent elusive to say the least. The purple one starts out darker coloured too. It was the most expensive of them all, but with the Garden tokens I did not miss it. The book says they even come with almost black coloured flowers!
You know I'm really glad you've started this thread, they are really lovely but I always thought I was missing out on something r.e. the smell. It's good to know I'm not really. It's like when I bought one of my clematis and they said it had a delicate smell. I've yet to smell it and i've had it for years.
