Hi Sue! I took a look at your registrations and they are very nice! I especially like 'Gekko Garden Miss Melba'. I love that they are late and very late for you.
I have the same issue as Elena. Buy a daylily that says it is late only to have it bloom in late July. My own fault for not checking where it was hybridized and registered.
As far as what the season extenders should look like, I would be inclined to love anything that would start blooming in August or September. I tend to like taller daylilies like the ones you have registered (over 36 inches).
It is too bad about the import ban, but being proactive may prevent spread of the disease until hopefully treatment is found. I have lost four roses to Rose Rosette Disease, also no treatment found to date, and it is spreading more all the time in the US.
