I think your difficulty would be getting them started, Alice; I think all those luscious roses will need to be cossetted enough to keep them from drying out completely in harsh winds, in their first couple of years, but once they get their roots really down into the rock cracks probably most of them would be pretty resilient. In a hot bed facing SW on chalk, in our French garden (not to be compared with your fierce conditions, but it does get very dry and hot in summer) Climbing Lady Hillingdon always looks good still at the end of summer. On a mainly shady wall there Aimée Vibert is fantastic (and virtually thornless - a great asset in a climber, as Mermaid's many admirers will ruefully admit); it also at least survives in our own hot Greek garden, and for friends there that we've given it to. Of the plants mentioned by Trevor, Alister Stella Gray has flourished in our most exposed and windy (French) site, looking fine after this unusually hot dry summer there. And at the end of the fiercest heat Général Schablikine burst into abundant bloom with the very first rain. All these plants, though, in the French garden, are at least 20 years old, most around 30, so their root systems are probably extraordinarily extensive now.
