How do I solve a problem like Safrano?

It has never been the same since I moved it out of the comfort of the porch (in this case more like a small conservatory with a solid roof). I moved it outside one summer, as I was supposed to do, and yet it never really picked up, although it did do much better when I brought it back indoors - too well, it got quite big, but not much bloom, and aphids had come in with it and thought it was Christmas, and I had an infestation of titanic proportions to deal with. So that didn't really work too well either! It has been outside again this year since April/May, and after a slight prune to get it in order, it has pretty much sulked all season. Plus the leaves went very small and crinkled in places, and it seemed to start sprouting shoots from the stems like a potato with eyes! Now I don't know what to do with it. Plant it outside for good, or keep it in a pot? Any suggestions welcome.

Despite this rose not being listed as thornless (or almost) I am finding it easy to get along with. There are some thorns on it, but they are easy to work around, and don't seem to be where they'll cause much trouble.

It is perfectly possible to deadhead the entire bush without gloves, and without getting ripped to bits. You don't even really need secateurs, as the pedicels are easy to nip off with just your thumbnail and forefinger.

The other nice thing about large Teas is you don't have to grovel around in the dirt to work on them. Everything is at a handy height, at least until they get so big that you need a ladder.
