I planted Thundercat in the Fall of 2020. Last year, it did very nicely, blooming from July 2-20, with 18 flowers. In the Fall of 2021, it was up to 7 scapes but this Spring 2022, I only counted 6, so it lost one over the winter.
Thundercat is a big showy flower with a lot of splash. I planted it near Wild and Wonderful which is similar enough to be confusing. But they sure look great when they are blooming!
