Marilyn Morss Johnson bloomed for me this year on June 9, 2016. And then again on July 11th. I did not record stats, unfortunately. At that time there were 2 fans. Checking it today, I see 1 single fan. So it has either gone summer dormant or this plant is decreasing and failing to thrive. I hope it is just heat dormant because I love this cultivar and would be so disappointed to lose it.
Here is a bloom from June 9, 2016:
And here is a July 11, 2016 rebloom flower:
I've had a lot of rain lately, so I do see a small amount of rust showing up on the single fan. Nothing serious yet. Just sad to think this cultivar may be declining in my garden. I have no idea why. New bed, lots of water and fertilizer and adequate daily sun.
