I have had CW since 2015. It has taken awhile to really get established, at no fault of its' own. She got moved twice due to a home siding project, but has been in her permanent home now for 2 years.
She has consistently bloomed the middle of July in my 5b garden. She is on track for the same this year as I have 2 scapes as of June 22. Height and size of bloom are as registered. The plant habit is nice.
Overall, she isn't my most favorite plant. There are so many out there that are more vibrant and showy. But she does look awesome when covered with dew and raindrops
