... I think you have flore pleno. I looked it up this year because I think I may also have it. Here's a link to the description of the difference between flore pleno and kwanso:
Basically, they differ in the number of petals (I believe, given the scientific terminology, and welcome correction with explanation if needed!). Kwanso normally has 7-12, flore pleno normally 15-18. Looks to me like both of your picks show between 15-18.
Also, it is said to be less invasive than Kwanso, though both reproduce from wandering root systems.
