I can understand that growing daylilies in pots in Florida would have its problems.
Light coloured pots (white) would help with controlling the temperatures and the speed at which water was lost from the pots. Using a double pot system (pot-in-pot) would also help control the temperature of the pots (which contained the soil and daylilies). The larger outer white pot (empty - no soil) would need to have an air gap between it and the inner (white?) pot. The larger the air gap the better, to a limit, since too large an outer pot might allow sunlight to directly hit the surface of the inner pot containing the daylilies. That would be undesirable for keeping temperatures down. I do not know if the outer pots could be large enough to allow the water tray/saucer/etc. to be completely inside it and out of direct sunlight. If the white pots that are available are not large enough then perhaps large enough black pots could be painted white or wrapped with white (or reflective) material of some sort to help reflect light or otherwise reduce their temperature.
