Do Daylilies change their flower type from time to time? In my picture "old daylily" this is what the flowers looked like up until this year. Now this summer the same plant is producing markedly different flower types... see "New daylily" photo attached. I am stumped! Thank you, Ann Poitras
If a daylily is allowed to set seed and the seeds are not removed then they can fall to the ground and germinate into a new daylily plant. That plant will not be the same as its parent but may be quite plain. It may also be quite vigorous and outgrow its parent as time passes. If that is the case then after a few years only the seedling will be growing and flowering and then some may look at it and consider that it looks old-fashioned and like an ancestral daylily. But the original plant did not revert; it was more or less killed by its offspring and the offspring was not a parent or ancestral daylily.
