The last, but far from least, suggestion I have is to give them room to grow . Daylilies are so vigorous that the new plant you put in will look nothing like the clump of five years later. It may look sparse at first, but have faith. With a little TLC to get them started, your new daylilies will quickly fill in. One exception to this would be a trick I call clumping.
Daylilies are fun to design with.
Try new things, observe, and learn what you like.
