Stella D'Oro is a dwarf daylily and there are lots of other dwarf daylilies available. However, you may have to order them. Here is one nursery and here is another. Do a search for "dwarf daylily" to find others. I think it is better to buy potted rather than bare root, especially as we are into summer, and the seller should list how plants are shipped. Familiarize yourself with those you find interesting; bring a list when you are shopping as you may find some at local nurseries.
