I acquired a small clump of 5 fans at the end of July 2015. They were transplanted into a new raised bed in October 2015. It did not bloom for me this year (2016) and it has decreased by 1 fan. I now have 4 fans with skinny leaves that are currently showing some thrip damage at the tips of the leaves. I hope it will bloom for me next year. I am disappointed that it has not done better, but perhaps the fact that this bed only gets sun for part of the day is the reason for a less than stellar performance.
