Thanks for the replies. I was interested to know if there may be others that experience multiple losses of related daylilies. I have not kept complete records so in some instances I am relying on memory to recall some plants lost over the years. I mentioned the three examples in my post as those got me thinking that putting plant genetics and climate conditions together led to the losses. You are all on to something that only good record keeping could help to answer over time. I don't like buying even a $20 plant that only survives one growing season.
I even changed my hybridizing where I have wanted to let new plants settle in for a growing season before using them or some would consider cutting off new scapes to let plants establish better roots. I have had a few new daylilies not survive for a second season so I will just use them as soon as I can get them to bloom. Texas Kaleidoscope and Cosmic Kaleidoscope are good examples. They only grew one season and died, but I have 2000 seedlings form them.
We do grow all our seedlings outdoors and it is survival of the fittest.
