"Some daylily cultivars stop making new leaves when the scape appears; other cultivars make new leaves until after the scape is visible but stop making new leaves after the last bud opens; "
Maurice,
I observed this on daylilies last year. Is this dormancy of a sort? Meaning the plant as a whole? Do fans on the same daylily without scapes also quit making new leaves? I wondered last year if it was due to the excessive heat and if it might be a sign of the plants weakening. However, sometime after bloom but well before the heat was gone, most of the plants were clearly growing actively again. I'm going to watch this one a bit more closely this year. There seemed to be a definite rest period toward the end of blooming and then a resumption of active growth. I'm not sure it wasn't heat related or tied to another cause though, because that rest period also seemed to be occurring in the plants that did not bloom. It's possible those formed scapes that simply aborted and were still on the same schedule as those with successful scapes.
