coneflower- strange green bud. aster yellows??
Comments (6)I had a coneflower with buds looking similar to yours. I finally took a bud, sliced it in half and looked at it under a microscope. I definitely found mites. I could not see the mites just by eye or with a magnifying glass. Of course, this does not rule out aster yellows, but it did make me feel a bit better. I decided to keep that plant. If you do not happen to have a microscope handy, you might be able to take the sample bud to a local group or agency that does have one. If you live near your county extension office (run through your state's land grant university), they might have a plant diagnostic lab. A local university or community college might have a plant sciences/ag department that could look at it. Sometimes even state parks with education centers have microscopes available for community use. A local Master Gardener group might be able to look at it as well. gl whatever you decide to do!...See MoreEchinacea - Yellow Asters Disease

Comments (2)I say no to asters yellows... The cone just isn't dense like they typically are. Yes they are hybrids. How they get a consistent mix of colors from the seeds is unknown ( from what I could find out about them). If you save seeds... There will be a shuffle of genes again... Including any common types you might have in you neighborhood. It's worth a try... I haven't seen of any second generation Cheyenne spirit plants yet so go for it!...See MoreYellow Aster Disease confirmstion in coneflower
Comments (5)You have a pic of the goldenrod? Goldenrod isn't on this list of host plants. The list is quite long. I've seen the witches broom growth on goldenrod before... didn't know it might be AY. My father had a few echinacea and rudbeckia get it He wouldn't pull them out cause he thought they looked neat for a few years They were surrounded tight by the same plants. I pulled the infected plants at some point and there hasn't been any return of AY since... two seasons now https://ipm.illinois.edu/diseases/rpds/903.pdf...See Moremarricgardens
