I have some mutant Rudbeckia. What is happening to these plants?
I have let this area reseed itself and am trying to have it fill itself in. Should I pull out the odd looking plants? As you can see some of the blooms are green and very small, Some of blooms have tiny blooms growing out of the center of the flower...I have never seen this before.

as soon as the temps go below 99F today I will start pulling up the diseased plants...Drat...that will really thin out the garden. Thank you for the quick response!

I have about given up on Rutabeckia. They are perennials that don't come back, get all kinds of rust and fungus problems, and seem to spread their troubles to plants nearby. I'll admit that I probably am doing something wrong, but I find it easier to just not bother with plants that I find difficult

minnesippi, sorry about your purple cone flower. I planted some seed a few years ago and finally this year, it bloomed. That's right, I have one from a pack of seed. Not much sense in worrying about things that just do not grow very well. Luciee {;^)

And today I pulled up and put into the house trash, a rudbeckia with yellow wilt. I am thankful to you all that I read this info here and knew what to do. Thanks to all, Luciee (;^)

I have found it in my sunflower, monarda, phlox and cone flower..and powdery mildew is especially bad this year as well. I have never had either before and now I have both. Maybe it was the 90 degree March and hot June & July?

I've not heard of aster yellows disease but I do have Rudebekia Goldstrum and until I found that variety I had the problem keeping them growing every year.
I was told that it is the hardiest variety of black eyed susan.

When I looked up aster yellows on the computer, I found out that there are a number of plants which are susceptible, including marigold, which is a staple for me. Now, I am not going to be surprised what I find it on. Luciee {;^)

Don't be too worried yet, it is a disease spread by leafhoppers so if your not organic, fist step, spray insectiside. Second step continue pulling any plant with first sign or starting to wilt (do not compost these plants, throw them away). I had it go through my garden this year and I'm still seeing it pop up because it was wide spread this year for some reason. About everyone with coneflower in town has it and many are oblivious. Its obvious their flowers are sick and they are just letting it spread(small town). It seems like the leafhoppers that went through only mostly really like coneflower and some rudebekia. Hopefully your leaf hoppers have a preference too.
