Gale - This is a GREAT thread! One of much interest to me, personally. Thanks for thinking of it and starting such a good topic thread!
I do not know about the plant habit yet on most of my seedlings (of known parentage), but I can recommend a few parents of seedlings I currently have that I am already impressed with:
Buddy Hudson - I have a few seedlings using this one as a pod or pollen parent. The blooms so far are perfect every time. Even in rain or heat. (Not sure about cold weather since I live in Florida.) This for me is a good one for ruffles! Has shown to be quite fertile, especially pollen. And has shown some rust resistance so far. (Fall will be the real test!!! So the jury is out on that quality!)
I like Victorian Lace for ruffles too, but it is rust susceptible ... all my seedlings from it have had pretty bad rust. But I will keep them anyway because I need to have rusty daylilies in my gardens.
Dragonfly Dawn - If you want patterning on a bloom ... this is my favorite one to use! Very fertile both pod and pollen!
Laughing Clown and/or Zanti's Misfit - This is my favorite seedling cross so far for crispate uf/spider. What I like about it is the sturdy, thick scape which is relatively tall, it produced a lot of blooms on many branches, and it re-bloomed. Definitely a good parent to use here in the south. (Not sure about north as it is evergreen). I think the genetics came from Laughing Clown, but ZM looks like it also produces some good scapes and lots of blooms, too. I have not seen any rust on these seedlings. I don't own either parent of this cross, so not absolutely sure which parent contributed what. But I am using my seedlings in future hybridizing of spiders/ufs.
I probably have more, but those above come to mind immediately because they left an impression on me this year with their first year children's blooms and plant habits.
I appreciate any comments posted with your lists! Thanks so much! Great idea for a thread!!!!
