Jan -- I'm sure you're joking, but chunks of ice were my "secret weapon" for getting SDB bloom in southern NM. On very cold mornings, the dog's water pan would be iced over. Fragments of broken ice scattered around SDBs significantly increased the bloom ratio.
Of course, the dog was a St. Bernard and his water pan was a standard stock tank next to the SDB bed so we're talking about more than a few ice cubes.....

Chuck, Magnificent! Now when can you get this flower combo onto an IB, BB, or TB so it will grow here in So.Cal., the land without cold enough winters?? Do you think that ice cubes would work?
