acquired this plant (4 fans) in August 2015,
made 3 scapes, I noticed the first one 4-4-2016
April was very cold and wet here, May had cool evenings and nights, days were around 65F

First flower was 5-13-2016 and didn't open very well.
At the end of May temps were a bit higher and flowers looked great

Beautiful flower. Thank you for posting it . I am going to look for this to go in my collie Liams memory garden
