Lovely seedlings, everyone!
I don't know, Sue. I would think the more age they get, the more they are going to bloom the way they will when they are totally mature. On the other hand, you know how daylilies are. If they've had a stressful summer: Drought, contention from weeds, trees growing into their space, overfertilized, underfertilized, unusual heat, unusual cold... I think those things can impact flower color and how they open, so I just don't know. Would be kind of interesting if 46-6 bloomed like the middle picture most of the time. Kind of reminds me of trillium.
