Donna: That is how new rose cultivars are "discovered" , ruling out the odd "sport" that Mother Nature breeds. All the famous Rose Breeders, i.e. Kordes, Tantau, David Austin, Weeks, and on and on do it continuously. AND, numerous individuals play at it, sometimes with amazing results. It does take a lot of work, in that you have to isolate the rose you want to pollinate from insects, etc. and hand pollinate it with pollen from the "donor" you want to cross with it. Then you have to plant the seeds from your crossing, and plant them out and wait a few years to see what appears? Lot of work but it certainly can and is done somewhere on this Planet all the time. I know you accidentally misspelt "patients", but there is the probability that one could wind up being a "patient" in pursuing this quest! LOL. Go for it! Cheers!
