From the few examples planted in a flower front bed a few years ago, the Purple Coneflowers have needed no care at all and multiplied in a way very pleasing to us, and to pollinators both resident and passing through. There’s a honeybee on a flower in the lower right quadrant.

Lovely. Mr Honey Bee surely loves your place.
Thank you! A store owner about 200 meters away has several hives so I’m sure the word is out in bee-world.
These are one of my favorite flowers. I’m glad to see that others are having good success with spreading them.
Thank you for commenting! We planted some about seven years ago and let them go to seed every year, so they spread on their own. The same bed hosts Gaillardia, ferns, lamb’s ears, columbine, cilantro, and other things I can’t think of offhand. We are happy to provide needed habitat and food for pollinators. Less yard to mow is a bonus.
