After much frustration, of trying to open a zodiac room over and over waiting for him, and he never came. It dawned on me. I had used him a few moments before for oceanic room. So I closed out my app, did the delete thingi at bottom of iPad and reopened game. Went to the room, tried once and there he was. I tested it a second time, as I needed seeds for Sakura as well, worked the second time as well.
No more long waits.
