Azalea Mollis

This azalea seems to do well in its pot, but I think it should be planted in the garden where it can flourish.   Unfortunately there isn't enough room in our borders to re-site it.  I think we will just trim its roots and repot it for another year when it finishes flowering.  Other suggestions welcome!

Thank you very much for all your comments and stars recently.  I'm afraid I am rather muddled and very behind with comments.
