When originally purchased, this plant was labeled "Lobelia cardinalis," but it is not blooming like a cardinalis. Could you please identify it for me? Thank you.
this looks like it's in the family of the "Cone Flower" which we know very well "Purple Cone flower" the one you sent the picture of is "Hot Summer" this flower comes back every year..it is hard to kill this one...it can be hardy to zone 4 and is easy to care for...just water it...the picture you sent shows a plant needing water...hence the wilted ones...it is good to deadhead this flower....b
Planted coneflowers outdoors and they started to turn black. Sprinkled with Sevin dust and they continued to die. Pulled stalk out and no roots. Will they come back next year or are they dead? What was the problem - bugs or disease?
If the coneflowers started to turn black soon after they were transplanted, they probably died either of transplant shock or of overwatering:
If instead they flowered and then dried out, this is normal and just due to the lifespan of the flowers.
Also check whether any of these possibilities match, especially sweet potato whitefly:
After they have died off, should they be cut to the ground? Thank you.
You can optionally cut back coneflowers to 4 inches off the ground. Leaving them in place until spring is fine too.
I want to put some type of support around the cone flower to retain it and hold it up .
You can purchase round wire supports that can be placed around plants.
Various sizes should be available at most garden centers.
