Arlene - Thank you! I was relunctant to say that some of the "spiders types" in my garden have the thinner leaves, but that is what I am also seeing. When they do bloom, they produce numerous blooms .... better than many of my wide leaf seedlings. But it seems to take them a year longer to bloom during which time they expand into a clump with numerous fans. So I am still thinking that they need a decent clump to bloom. I've never had a bloom on a single fan of a thin leaf daylily.
