Of the 3 lilies I have in z5, 2 hardy, 1 tropical day blooming, they all
open fully by around 9:30 a.m. (start opening around 8:00) and close up by
around 4:30 p.m. There are night blooming tropicals (tropical lilies not
being hardy in z5, much bigger spread, more floriferous, more choice of
colors) that bloom at night, opening around the time the day blooming ones
close.
