I have noticed that these late bloomers (rebloomers or extended) generally take a day and a half to 2 days to open, then they tend to be "two day" lilies, instead of just "day"lilies. It is not unusual, at least for me, to see less saturated color or missing bands of color
I took these photos this evening in the dark because neither of them were open enough this morning:
Purple Pashtina rebloom
After Awhile Crocodile continuous bloom
This is very unusual for blooms this late. Our weather is very normal, we have been touched by mild frost. Even last year with the extreme heat I didn't have blooms this late. I suspect all that spring rain and the late arriving summer may be affecting this - I am not complaining, I haven't even covered anything to protect them this season.
But I am hearing rumors of snow next week, so I guess I had better enjoy them while I have them.
