Answer: You can start a new plant from a tip cutting. (Keep in mind that many of the florist roses are not winter hardy, in case you are going to try to root one from a bouquet.)
Here are some instructions on how to take cuttings from shrubs. You may need to cut and paste the url into your browser to make it work correctly.
You might also consider layering, if it has long flexible canes. This takes longer but is much easier in terms of ongoing care.
Good luck with your project!
