The hybridizer, Morrie Otte, lived near Pittsburgh, PA, if I remember correctly and he died around the time I was becoming active in daylilies. My best guess is that if you contact one of the co-presidents of PIDS ( Pittsburgh Iris and Daylily Society), his former club, and ask them to check with club members who might be growing it, that would be your best chance of finding this. I doubt that many of his cultivars are well distributed outside of Region 3. The co-presidents are Dan Taylor and Gary Ball.
Here's the link to the Region 3 page where you can find contacts for the Pittsburgh club:

Good luck~
