Long-term survivor for me. Bought from the hybridizer in 2007 at a Gulf Coast Daylily Society [RIP] plant sale. It was moved north later and has survived neglect, oak tree roots, shade, terrible "soil". I moved it to improved soil and [temporarily] got rid of the roots and hope for a good bloom this year. I don't recall it ever showing rust here but then we get quite cold over the winter.
