There is no reason to expect prime performance from a daylily without giving it good care. Fertilizer, no competition, water and sun. That's about it. While I do live in FL, I most often get 4 mo of rebloom from my evergreens. I fertilize a lot ..... really, a lot. They are in raised beds in really good soil. Unfortunately they get salt in the air and salt from the irrigation water. Neither slow them down. In the last 3 days, they have just jumped with growth--looking really good. Last year the first scape came up in the 3rd week of Feb. May not be that this year, but I keep looking.
