I planted ROTKB in the Spring of 2021. It was my first Judy Davisson plant! I got a grand total of one flower that summer. By October, it was up to 5 fans, which is where it has stayed. This summer, it bloomed from June 27th to July 7th with at least 20 blooms. It's such a cutie! Very little to have an unusual form, a nice clear school bus yellow. And it's nice that it blooms EM.
