  • Posted by Hortaholic (Columbus, Ohio - Zone 6a) on May 29, 2023 11:12 AM concerning plant:
    'Stella Supreme' is a valid cultivar name, however it is not registered with the American Hemerocallis Society, so it is not in that database. Because it is not registered with AHS, it is not eligible for any AHS awards. Nor can it be exhibited in AHS accredited daylily shows.

    This is a commercially propagated Daylily cultivar. Unlike many of those, it is not a patented daylily, nor is there any indication on sites selling it that the name is a trademark. It can be freely propagated and distributed under the name 'Stella Supreme' by anyone.

Brightstar3 On June 28, 2023 Miscellaneous Event
I found two more scapes on my yellow daylily today, which makes me wonder if it is Stella supreme. According to the database, she has six scapes and is a dormant daylily, while my yellow daylily has ten scapes so far that I have counted, and appears to be an evergreen. She has been putting up two scapes over the last two days. Are there any yellow evergreen Daylilies with more than nine scapes?
Brightstar3 On June 26, 2023 Miscellaneous Event
Possibly a tet, since it aborted the seed pods when crossed with rajah and raspberry pixie
Brightstar3 On June 8, 2023 Bloomed
First two flowers from Stella supreme?
