Sunrise Elegy was slow to start for me. I got two rhizomes in the PNW sale in 2013. Neither bloomed in 2014 (which was sort of expected as it was received on 9/21. This year only one of the rhizome "clumpettes" bloomed this year. I dug up this bed this year as the whole bed under performed and my guess is the dirt needs some amending. I expect to se both perform well this upcoming Spring.
It needs a "settling in" time.
