For the last 2 winters I have bought very cheap indoor roses from Morrisons and elsewhere. They flower well for a few weeks. When the weather gets warmer, I repot them into Verve compost or similar with Fish Blood and Bonemeal mixed in and put them outside. They will then go on to flower in the summer, which is their natural time for flowering. I don't quite know what the Nurseries do to get them to flower in January!
I have one that bloomed very well last summer, it is now in it's second year, it's doing ok, but I know that it would flourish more in open ground. I don't expect it to last another year.
