I acquired 2 fans of Webster's Pink Wonder in September 2015 which were potted up. It was transplanted into a raised bed in October 2015. It produced 2 scapes in 2016 and bloomed the beginning of June probably through the middle to end of June. Large blooms that didn't hold upright straight on the scapes. The scapes leaned from the weight. Maybe as it gets more established the scapes will become stronger? Just a handful of blooms per scape.
Here it is a year later (Fall 2016) and it has shown no increase so, it remains at 2 fans.
The early blooms were weird-looking producing some blooms with only 4 petals:
The final bloom looked quite nice:
