That's the only name that I know it by. Mine was given to me two years ago by the neighbors across the street. They had dug it up from their grandparents place when the grandparents passed away, and thought I needed some, since I had given them a ton of ditchlilies. I had no idea what it was when it bloomed, but I loved it! I then found out that it can be very invasive, so I had to move it out of my regular daylily beds to a more secluded spot where it could roam all it wanted. It has been very busy doing just that! If I can find my picture of it I'll post it here.
