You should probably look up the "asters yellow" virus and how it expresses in echinacea. If you the flower petals are green then you need to pull the plant and trash it immediately before it can spread to other echs or other plants/veggies you may have around.

This is what im told is asters yellow

Nevermore: Am I glad you posted this! Some of my echs have also bud centers that are twisted. Not all of the plant is affected, but I'm thinking if it's a virus the whole plant needs to go. Argh! What about the soil it was grown in?? I have to read about this. Thank you.

Do you have an opinion about all the seedlings I've been getting? And about the fact that the flowers are so much smaller and more pale? I've read that hybridized plants don't reseed true to form and wonder if that's true with Red Cone Flower too . . .

I planted those same two coneflowers and have many healthy seedlings all over the garden. I never could tell Magnus from Rubenstern, and to me all the seedlings look like the parents. Which is to say, they look strong, colorful, and vibrant. I love them.

So I'm not sure what's going on with your seedlings, but I might yank out the weak ones and see if you get some better ones down the road.
