I purchased Ninja Storm at the Nebraska Daylily Society auction in the spring of 2018. It bloomed last summer. I recall it being pod difficult, but the pollen was good.
It survived the winter and has increased. This year's scapes are sturdy and thick and three fans are showing instant rebloom. NS is not even listed as a rebloomer...
Bloom in 2018.
Ninja Storm so far this year. I've numbered two of the three rebloom scapes. The third is on the backside.
