"I think it would be a very sad and one dimensional world if we couldn't appreciate something and grow it simply for its beauty. "
True. But that's not what permaculture is about. And in fact, most plants we grow for their beauty are not just beautiful. They have other dimensions as well, and that's when they would have a role in a permaculture landscape. Otherwise, we are talking about something like an English Border, or formal beds. Or even a potted patio plant.
