The ones I mentioned are all summer flowering group 3s so are grown like the viticellas and very hardy.
In my experience, Mme Julia Correvon and Hanna are wusses that don't cope with hard winters. Betty Corning has nodding, lilac/blue-ish bells which are perfumed. Caerulea Elegans is another toughy but not perfumed.
