What type of rose is this?

An identification would be good, but I would like to no what type it is so that I can look for other varieties - if they exist.
I bought it in Woolworths so that might give a clue to his old it is.

It's in a dreadful dry spot but soldiers on, poking it's head above the shrubbery and flowering all summer.

 

Anyone got any ideas?

 

No, but it’s very pretty.
