Hi Theresa,
For now, don't worry about registering anything. If you do, that will be down the road a ways. Just have fun ! Look at your daylilies and think what traits do you see in one, that you might like to combine with another. Most people do like to know both parents, so you might want to label your crosses. If you have your daylilies labeled in your garden it is very easy. There are many methods. I use the paper string tags that you can find at an office supply store. Just write the name of the flower that the pollen came from on the tag and loop it around the flower you are pollinating. Simple. Use your imagination and enjoy !
