without knowing the flower color or height - it's going to be very hard to figure out what they are.
I don't know of a "master list"… or the term "dwarf" being used in daylilies in the same way as you would, say, an apple tree. There are mini daylilies, but it refers to the size of the flower, not the size of the plant (I think - I don't grow many of the tiny flowered ones)
A couple popular smaller ones sold at nurseries are Stella D Oro (hope I spelled that right
) and Happy Returns. Stella is more of an orange egg yolk yellow, but Happy Returns is more of a clear lemony yellow. Stella is known for making a ton of seed pods. Not sure about Happy Returns.
