Are the bloom habits prompted by weather (heat), rain (water), or by sun cycle .... or what?
Daylilies will bloom once they reach their own specific mature or adult size (ie depends on the cultivar or genotype). That presumably applies to each fan of a cultivar independently. How quickly that happens depends on how fast they grow and whether they stop growing during certain times. How fast they grow does depend on the weather. The amount of sunlight will be important but usually the most important factor is the temperature. Below a certain temperature a daylily fan will stop growing; above a certain temperature a daylily fan will suffer. In between those two limits a daylily fan will grow faster the higher the temperature and vice versa. Water and fertilizer, usually, especially nitrogen, also affect how fast a daylily will grow.
