Seedfork - The daylily blooming times you quote from the other site were mine. I will tell you we had very unusual conditions in Nashville that year - a flood the first week of May 2010 that resulted from 13 inches of rain over a two-day period. Those cultivars are long blooming, but I don't think they've bloomed that long since then. Edge of Your Seat is a terrific rebloomer and my best rebloomer this year, putting up four instant rebloom scapes. Some years it has three cylcles of bloom, but I doubt this will be one of them because we had almost no rain in May or June, and I did not do a great deal of supplemental watering because I had to be out of town quite a bit with a sick relative. I can tell you Edge of Your Seat has been blooming continuously since June 13, and the scapes still have 6-8 buds to go. Uninhibited also bloomed well and rebloomed, although I do not have the date of its ffo. Bella Sera and Adamas had very poor bud count this year and have not rebloomed. I Remember You bloomed for 36 days, and has not sent up any rebloom scapes. Royal Jester has just started last week. It has a bud count of 18-20 this year. Others that have bloomed for up to 60 days in the past are Ruby Lipstick, Blushed With Emerald, Wonder of It All, Moonlight Sail, and Stealth Bomber. In my opinion what makes optimum conditions is plenty of rain in late April and early May for scape formation.
