Good advice Lyn!
I bought 17 roses from the Chamblee co-op in the fall of 2010. They all got potted up, no way would I ever plant then directly in the ground that small, some were very tiny. I only lost one. Some took a while to grow, maybe not the best candidates for own root. Two are still in pots as I haven't quite decided where they will go. They just progressed to larger pots as they grew. The ones planted in 2011 and 2012 are all huge. Westerland is easily 6x6, Molineaux is almost 7 ft. tall, Graham Thomas has reached the top of my satellite dish pergola this year, Cinco de Mayo is 4x5 and a bloom machine.
