I wrote a lengthy reply yesterday citing merits of specific plants. My overall experience makes it easy to conclude that there can be highlights and pitfalls regarding too much shade or too much hot sun. Some hybrids are more tolerant of one or the other. Gardening at home is all just a grand experiment and sometimes just moving a specimen 5 or 10 feet can make a dramatic difference. Folks growing commercial quantities face a much larger challenge.
I would lean for too much hot sun here in 6a before burying something in shade but that can't be true in warmer climates. Those best producers in your landscape probably have as much to do with balance as individual hybrid traits. I just experiment, and without naming names many of my daylilies like a little shade. Several of my favorites get baked with the mid-day blast of sun pinned between a concrete walk and house foundation. With enough water they're happy so they stay where they are. I move others around until I'm happy. The gardening experience...er... experiment.
