I liked this one so much that I accidentally bought it twice last summer
The DF I received from David's Dragonfly Farm in GA bloomed shortly after it's arrival here in June. The scape was short, as to be expected for such a new plant in the garden, but it was exquisite. My picture did not do it justice, even for its FFO.
The other SF I received was a complete wimp. While it did finally grow later in the season, it was just a tiny sprig of grass for most of the summer. This cultivar makes smaller fans in general, as stated by others in posts above.
I look forward to this summer to collect some true stats, and am looking forward to seeing that beautiful cascading pink bloom
