Seems like a long while ago since I started this post Carol! In the intervening 3 years I have indeed got exposed soil in my courtyard - soon to be home to Mahonias Winter Sun and Buckland. However, I have also been growing Mahonia Soft Caress in a pot for nearly 3 years now, and it is doing very well.
so I think the answer to your question is that Yes, you can grow certain varieties of M in a pot, but only the small ones like soft caress (which, to my mind, looks more like a little palm tree than a traditional mahonia)
