Echinacea purpurea (L) Moench is the correct and accepted scientific name for the Eastern Purple Coneflower. The genus and species were named and described as such by Conrad Moench in Methodus Plantas Horti Botanici et Agri Marburgensis in 1794. It was first named Rudbeckia purpurea by Carl von Linnaeus in Species Plantarum in 1753.
Plants of the World Online by Kew lists nine species in the Echinacea genus (as of 10-19-21 when this page was last updated). It is a member of the plant family Asteraceae with 1,677 genera. Those numbers could change as updates are made on POWO. The number of genera in the family fluctuates quite often.

I dug several divisions of this Echinacea purpurea from a business north of where I live. I have been “eye-balling” them for five years and finally decided I would ask if I could have a few divisions. I took the owners of the business a couple dozen eggs in the spring and told her I would clean up the bed if I could have a few divisions. She said, “Yeah, sure. They aren’t ours.” Well, they rent the building… So, I cleaned out the bed and removed all the previous year’s dead leaves, stems, and flowers. Then I brought home a few divisions.
I am sure the plants I brought home are a cultivar and not the “native” species. I haven’t grown the native species of Echinacea purpurea yet, but I intend to do so and have them in several locations throughout the farm. There are a lot of them growing along the highways. There are also many cultivars I would like to try. The plants I brought home could be Echinacea purpurea ‘Magnus’ but since I am not sure, I am not going to say that’s what they are.
I put most of the divisions n the flower bed behind the old foundation where my grandparent’s house used to be.
I put other divisions in the southeast corner bed the house. Only one survived transplanting in this bed.
Zones: USDA zone 2a-10b (-50-35 ° F)
Size: 24-26” +
Light: Full sun to part shade
Soil: Well-drained soil
Water: Drought tolerant once established
Propagation: Division and seed
The plants behind the old foundation did well and had started to bud when the above photo was taken on June 14.
I am very happy the Purple Coneflower flowered. Yeah, I know the grass needs to be pulled in the bed but sometimes I get busy on the farm, or maybe it is too hot. I know I will think of more reasons if you give me a chance. 🙂
After a couple of weeks, the flowers started to fade leaving behind the spiky cones. I never realized how stiff and sharp they were until I grew them myself.
I was happy to find the Echinacea purpurea cv. ‘?’ made it through the winter and was starting to come up when the above photo was taken on March 24.
All the plants in the planter behind the old foundation and the southeast corner bed survived the winter.
The Echinacea purpurea in the southeast corner bed is getting off to a good start. This is a tricky corner so I was very glad to see it returned.
And growing very nicely…
The plants in the planter behind the old foundation are growing very well, too.
By June 1, they are beginning to bud…
It is interesting how some buds look compared to others. The Echinacea purpurea starts out with very tiny petals…
Looking pretty good…
Looking MUCH better now. You can see how the petals have gotten longer. As days go by, the petals get longer and start to droop and the cones get larger.
The Echinacea purpurea in the bed behind the old foundation and southeast corner of the house have really spread and are looking great.
I think the flowers look pretty neat at this stage.
Of course, a Japanese Beetle had to get in a photo…
I will continue adding more photos and information as time goes by.
There is a lot of information online about the Echinacea purpurea but I just added a few good links below.
