I acquired a clump by getting this from two places this Spring. Great Expectations sent some and I picked up more from Cameron Stern at the NEDS Club sale. So in the Spring I had 11 fans, although I only counted 8 by October.
Rainbow Maker sent up a very late scape and squeezed out some very unattractive flowers from September 26 to October 16. I think there were 6 altogether. It was just too cold for them to open properly.
