I don't know whether these roses are all the same, but over the years I've planted out about a dozen, in my mum's rockery, full sun and open ground, and in a small raised bed of mine, sheltered and no sun, ever, and they've all thrived - I cut them hard back every autumn and they just keep going. Odd thing is they are now all the same colour flower, a sort of off-white - I don't like them much but I hate disposing of plants that want to grow!
