I've had RFK for 4-5 years, I bought a clump.
The second year I had it, RFK had nearly 100 blooms on the clump.
It's a great increaser, I have lots of it.
It only has about 10 buds per scape, but every fan even little ones usually have a scape.
The first year we had it we put it in everything, we probably harvested 5,000 seeds with RFK as a pollen parent. It sets pods very easily too.
It stands out in the garden.
RFK is definetly a garden favorite.
