Well it did take me some time (years) to decide to remove some daylilies from my garden, When it got to the point that to add one meant removing one. I would select those that were not performing as well as possible here in the north. I want all the bloom possible. There are now hybridizers here in the north who have some that have instant rebloom or bloom for a long season and higher bud counts all a plus for me. I am now at the point where I only add a small number each year so I do get some new introductions from a few hyridizers instead of buying a lot, so money wise it comes out about the same.
