I got my original Sandra Elizabeth from Seawright who inherited all their stock directly from Don Stevens, the hybridizer. When I bought it, I was actually told to buy the plant by Bob Seawright who claimed that ( at that time in the late 90s), it was the absolute last Daylily to flower in the garden. And it was! For many years! Eventually, that plant got lost when I was moving things around but when Seawright was going out of business ( 2012) I bought another one. It has formed a large indestructible clump on Lower Daylily Hill. Great Plant!
