Way back when it was first heavily marketed, I had trouble with 'Magnus" where I used to live, it seemed to revert to the soft dusky barely visible mauve, then vanished forever. It was a very sandy spot, not watered much. Or maybe this was a seedling and the original was not perennial. I tried again in new home, also sandy, same result. Years later, I tried several of the fancy colorful new varieties (I don't recall which ones) but they did not return. This was on clay.
Now I have clay, but improved with about 6" of purchased planting mix on a slight slope where water never puddles. I tried some more, 3 years ago.
I planted one Echinacea 'PowWow White', which did not return.
Two E. purpurea 'Happy Star', another white variety, do return but are basically a white daisy, they are just starting to bloom now. Trouble free.
Lots of Echinacea 'White Swan'. Also just a white daisy. Only three of these have perennialized, they will bloom soon. Trouble free.
What Echinacea have you found to be hardy perennials here in the PNW?
What conditions do they prefer?
What conditions do they dislike?
Springcolor planted several of the new varieties several years ago- are any of them ones you might recommend?
