I just read that the tropical night bloomer "Emily Grant Hutchings" can be
planted in an 8 or 10 inch pot to reduce the size of the leaf spread without
sacrificing flower production. Perhaps reducing the size of the pots may
improve your situation? I have no personal experience trying this and read
about it in the Perry Slocum and Peter Robinson book, "Water Gardening-Water
Lilies and Lotuses." They are well known in the water garden industry.

There are many dwarf cultivars that are naturally small in leaf spread.
