Water Gardening: Question about water lilies, 1 by newtonsthirdlaw

I have 2 minerature water lilies both for about 3 months now. The yellow lilly has sent up 3 flowers. The first 2 appeared at the surface but never opened and eventually grew down into the pond. The third flower opened 3 days then headed downward. I also have a changable orange and it is just now making a bud and I do not know what it will do. Why do the flowers keep retreating into the depths?
