I have lots of Daylillies I'm still waiting on but none of the Stella D' Oro yellows I think you are referring to. Still have orange (tigers) as well as some Little Missy I'm still waiting on. That Crimson Pirate is the one and only.
Nice! I have a bunch of typical oranges, and 6 one of a kinds that came from a friends breeding program. They didn't fit in to his vision of what he was trying to develop, but they're real beauties. Won't be in bloom for a couple months though.
Subrosa: I have attempted a few crosses myself but Idk what the success rate will be. I crossed an Easter pupu with a Hemorocallis Crimson Pirate and crossed a Durango and Easter lily. Will probably try more as things bloom. I have three Double Tiger Oranges that are developing buds and I cannot wait for.
