I've got plenty of daylilies that aren't as tall as they should be, but I'm positive that I've got the right plant. I know that it can also depend on where they are planted. I've got one daylily that I divided and moved to the front yard from the back. It's much taller in the backyard, and the one in the front has been there for 3 years now. The blooms are better in the front yard though. Keeps me busy scratching my head!
