Michele, your GD is beautiful! She obviously get her looks from you.
Most of the big northern hybridizers have greenhouses. Mike Grossmann, Jamie Gossard, Carol Emmerich to name a few. That some what even the playing field. Mike keep his at 35°f during the cold MN winters. I imagine you could go warmer but the cost could be astronomical. Solar energy anyone?? I started mine indoors around late February to mid March and had some blooms the next year.
Becky, I agree with Michele in regards to registering a daylily for a family member or friend. If you are pleased with it in your garden then go for it.
I have read of hybridizers that had ten to fifteen thousand seedlings. Somehow the name "Apps" is ringing in my ear.
