Susan I have no idea. I picked it up when I first started gardening 20 years ago. I do not know if you had a Big Box store called Hechinger. In PA it was replaced with Home Depot. I had just brought the house and it did not have any flowers and I went in there and purchased things and as BB stores go no name plants.
It is a crazy daylily. It blooms different colors depending where it is planted.
It blooms this muddy brown color in the shade. In sun it is a little brighter yellow.
I am looking for another pic. I planted it somewhere else and it actually bloomed pink and yellow. I gave it the name of Chameleon.
