Amber, I'm in the same boat. I have very little space but I love hybridizing! I'm not sure what the percentage of viable crosses were last year but it will vary with the weather. Some of my plants really suffered over the winter so I won't be surprised if they don't set pods. I figure your best bet is to make sure your plants are well watered & fertilized if you want them to set pods. The more stress on the plant the least likely they are to successfully reproduce. But if the weather doesn't cooperate there is nothing you can do.
If you have extra seed you don't need you can always donate it to the International Daylily Seed Bank. They give seeds to people in countries where they can't import the plants for free! I donated almost 50 crosses to them last year.
