I do not have this rose yet, but am very, very anxious to get one. Have only found in Canada and they cannot ship to California. How can I get one soon?

I have a question about the Osiris rose - can it be grown in a pot? We are renting and don't know how long we will be here, would like to take this with us when we leave.
