'Zoe Allegra' does very well here on the southeast coast of Louisiana. It is both pod and pollen fertile and makes lots of seeds.
I prefer tallish daylilies, so it blooms a little short for my tastes but it does hold its blooms well above the foliage.
I believe its patterning is at its best during cooler weather as the patterning tends to disappear as the temperature rises. BUT, with heat, it morphs into a bloom with prominent teeth. A one word description for this cultivar would be "reliable".
