Yes. However, sometimes cuttings put out new leaves before they have made roots, so you need to leave it right where it is (including inside of the produce bag - keep the bag blown up so it makes a little greenhouse). I would wait another 2-3 months to make sure it has time to really make roots before I would take the bag off and transplant it into a one gallon pot. Since it is indoors where it is so dry in the WInter, after transplanting it into a pot, I would still leave it under some kind of cover - I use huge soda pop bottles with the tops cut off.

Then when Spring comes you can gradually take off the pop bottle, and put it outside in partial shade for a few days, and then into full sun. Keep it well watered, and wait one year before planting it in the ground - by then it will be big enough to survive.

Presuming it survives, it will make a fine rose, just as good as any other. It will be own-root, of course. Do you know what rose this cutting came from?
