Thank Becky.
We cross our small flowers with all different blooms. Full forms, spiders, and UF's crossed with small flowers can still make some 5"-6" booms. Also looking at a longer time, if you get some 4"-4.5" flowers that are really nice, these can be the next step to larger flowers in future crosses. There are lots of registered daylilies that are examples. If you select the small ones for something you want to produce in larger flowers, then you will want to use them.
I must admit that some of the southern produced minis don't perform that well for us. Some have had no increase in 4 or 5 years and only bloom every other year. I am working on the small flowers in my hybridizing to try and make some with better plant habits but keep unique colors like the blue eyes. I think I am going to have to breed the evergreen out of some. There are some that are registered as SEV that the foliage is perfect evergreen all year.
