I've managed to overwinter a few broms in the greenhouse for a couple of winters now.

Love, love, love them but will never get to enjoy them being outdoors year around. As a result I am careful about the sizes I chose for overwintering indoors.
Also have a variety of Cryptanthus, Dyckia and another favorite, the Orthophytums.
