Hello,
I noticed this summer that a fair number (20-25%) of the Daylily blooms would only open up enough to look similar to a tulip. The average high in July when most bloom is 91, the average low is 57. I see Daylilies listed as CMO's, but at what temps should a person really start looking for them? Is mid to high 50's low enough for a fair amount of Daylilies to have trouble opening, or do you think it could just be a trait of those particular plants? The day typically warms up rather quick here.
Thanks,
Gale
