Thanks for the clue in the possible cause Hemlady. I have an unregistered seedling that I purchased that hasn't bloomed in 2 years. It produced scapes but they didn't grow right & all the buds dropped off. This year it has a scape and 2 out of 3 buds have dropped. I do think the last will make it since it is quite large now. The seedling is planted in a raised bed with several other daylilies and they all are fine. I guess that must be the tastiest one of the bunch!
