"The sudden bursting, splitting or severing of a daylily scape.
Scape blasting is usually caused by heavy rain following a period of
drought causing a rapid increase of internal pressures within the scape.
Fertilization just prior to or during a swift increase in soil moisture
may contribute to scape blasting. Sometimes the rupture is complete,
and all blooms are lost. At other times the rupture is partial and the
daylily will continue to bloom. Should the scape not separate
completely, the break can be supported with ice cream stick splints and
duct tape. Scape blasting has been attributed more often to tetraploids than diploids, possibly because of their thicker, less flexible cell structures."
You did say you had torrential rain , so that is probably the cause.
In my garden, the first person to blame would be a deer.
Deer could easily jump your fence, or get their heads through the bars. They tend to taste everything. What they don't like, they spit out. At this time of the year they are probably lactating and have a greater urge for flowers.
