I have given a lot of thought to that question and the way I grow daylilies my number appears to be around 150-200. That could change, but trying to keep up with dates for scapes and blooms really puts a limit on how many I can keep up with. I am around 150 now. If things should change even a little I would not be able to do that many. If I don't try to keep up with all the data I would be limited by available time and space(not planning on digging anymore beds) and that would be around at a max of 200 also. Of course that is named cultivars, my few seedlings and my NOIDs are a different thing.
