I like to cut the scapes that only have one or two blooms or buds left and bring them in to enjoy the next day. Usually in the morning they are all shriveled up. What kind of DLs would still be open in the morning? Diurnal? Extended bloom? Are there any two day daylilies?

Great question!
I occasionally observe dl that remain open a full 2 days, and others that may not be early morning openers that will still be nice the next day; haven't made any conscious effort to catalog them. I expect someone here has done so...

This morning I have a lovely "Breakfast Bouquet". last night at about 6:30 pm I picked the scapes with slightly open buds, rather than fully opened. And this morning they are all bright eyed and cheery!
These are the ones I picked:
Redefining Genetics
Raining Violets
Beautiful Edgings
Mount Zion
Driven Snow
Hyperion
and a few more that are nameless at present. Now I'm going to look these up and see if they are diurnal or nocturnal. Guess they would all be considered "early morning openers"?

The ones above that had an unopened bud on the scape are now open the next morning.

Hi, Caitlin,

I remember you from Dave’s Garden many years ago, and it’s great to read a post from you again. : ) I recall that you had some very fine pairings of nocturnal and diurnal daylilies along with companion plants that complemented the groupings. It was inspiring to see how seamlessly these plantings worked in your garden, and how floriferous the nocturnal and diurnals were during the early morning when you took photographs while both were in bloom. : )

Do I understand correctly that your Breakfast Bouquet was composed of daylily scapes that you cut from the plants two evening’s ago? You should check with the moderators (@Daylily, @Char) whether AHS would consider the subsequent performance of cut scapes, which were no longer attached to a cultivar, to qualify as EMO’s. I wouldn’t think so, but what do I know? : )

Happy gardening, Caitlin! : ) Elizabete

Most of the scapes I picked had only one starting to open bud. They were open the next morning. A few also had an unopened bud which opened this morning. Actually I don't know if they opened at night, or early morning! (I didn't wake up to peak.)
I don't remember the nocturnal/diurnal daylily pairings at Dave's Garden, but I was there; (actually I just renewed my subscription although I keep thinking I won't!),

I usually let garden visitors take home an arrangement of day lilies. I pick those that have not opened yet and have several unopened buds. I have had visitors tell me some arrangements have lasted over a week. Of course the flowers only last one day so you have to pick stems with lots of new buds to open over that period.
