Question: What part of the purple coneflower is used for herbal remedies? I have seeds that were given as a present, but was told the plant can produce an unpleasant odor. I don't want stinky plants, especially if I don't know how to use them or if they have a use. My gardening space is very limited and I want practical plants only.
Answer: The part used would depend on the species of coneflower and also on the intent of the remedy as different parts of the different plants have different chemical properties and would be used differently. In any case it is difficult to grow your own reliably because a home gardener has no way of ensuring quality controlled guaranteed analysis of the crop and individual plants and growing seasons can cause variations.
In my experience I have not noticed an unpleasant odor in purple coneflowers; Echinacea purpurea plants produce very pretty flowers attractive to butterflies and very easy to grow.
