Planted in Oct. 2015, so the plant is under 2 years old. It was two small fans when I first planted it, now it is 12 fans, but two of those are small recent ones. I pulled eight dead scapes from it today, and they averaged 27 inches tall, with three way branching and 12 buds per branch. This plant has done very well in my garden this year and I enjoy the large(6 inch) bright blooms a lot. The plant is currently reblooming and also has a seed pod on one of the scapes I left on it.
Only two small fans when planted.
I took the photos today in the bright hot sun, so this bloom photo is from an earlier date.
