We also have seedlings that can be used for their plant habits and genetics. These may be really good, even outstanding seedlings in many respects where the bloom is not unique enough to be an introduction. You may be able to imagine possibilities of crosses that could make the next introduction using these step or next step types of plants for hybridizing.
This Dan Tau x Cosmic Kaleidoscope seedling #12-346 is a good example. Since the first year it bloomed, it sends up multiple scapes and produces lots of large flowers that have improved with each bloom season. It is not so unique for an introduction but has so many good qualities that I have crossed it with several different daylilies for eyes and patterns. A little improvement for a patterned eye zone or an unusual color or shape of eye and keep the outstanding bloom habit on super strong scapes and we have something. The first seedlings from these experiments should bloom next spring.
Your Frans Hal seedling may just need crossed with right daylily to make the pretty face to go with the buds and branches.
