This is my 1 year later post, too.
Mine is still 1 fan. It did not bloom this year for me. It's just sitting there in a bed with many others that did not bloom this year. Those cultivars in the bed that did actually bloom, also re-bloomed. Go figure!
At least I didn't lose this one. But no increase at all. Still is a good looking fan. No rust. So ..... maybe next year it will bloom for me. I like to think that when daylilies are doing that, the root system is growing and will burst forth into multiple fans and lots of blooms the following year. But that is only wishful thinking.
