Can You Really Have Too Many Coneflowers?

I’m going to stay in the Aster family in honor of Native Plant Week (October 16-22).  I love Purple coneflower, (Echinacea purpurea).  My daughter, Shoshana, always said, “They’re such happy flowers!”

When I removed the last large portion of grass in my backyard for the large perennial garden that I installed, I decided that I wouldn’t buy many plants, but use seedlings of a variety of plants that I had from other parts of my gardens.   I always have scads of Coneflower to give away, toss in the compost, or replant.  So, except for a few other plants, initially this garden,

was primarily planted with Coneflowers.  I wanted to experiment and find out if it was possible to have too many Purple Coneflowers. Well, I found out, that indeed, it is possible to have too many. Not that they didn’t look wonderful when in full bloom, but after the main bloom time, the garden was a little bare. Also, I wanted the garden to be a true mixed perennial/shrub bed, so I removed some of the Coneflowers in that garden.  I still have many individuals of this lovely plant  in that garden and throughout my landscape.

The primary bloom period for Purple Coneflowers is April-July.  In full (or mostly full ) sun, they get 2-3 feet tall and are magnificent in bloom. The individual flowers last a long time and make a beautiful cut flower.

I also have a few as understory plants, in dappled shade.  What I’ve noticed about those is 1) the flowers seem to be a paler color, and 2) they only bloom once and the blooms don’t last very long.

Once summer heat sets in, Coneflowers start to brown–this photo is from late June.  You can see the tips of the petals becoming a little toasty.

Eventually, depending on  heat and rainfall, Coneflowers will  go to seed in July/August.  I rather like them as they dry out, but I prune most of them down to the base plant just to prevent every seed from development and germination. Typically, some of my individual plants bloom throughout the summer, although that didn’t happen this year. Purple Coneflowers are terrific nectar plants for pollinators and I’ve often seen birds (especially finches) eat from the seed head.  I have several stands of spent blooms that I haven’t pruned because I think they’re interesting and the finches are still nibbling from them.

Just right of the spent blooms, in this photo is a Coneflower rosette that I pruned in mid-summer.  Without regular irrigation, this is what they look like from August until a fall bloom.

Usually in the fall, there is another bloom cycle, although not as dramatic as the one in spring.  It is in the fall that the butterflies really enjoy the Coneflowers.  I’m not so sure about this year, as the butterflies are scarce and the Coneflowers haven’t bloomed again.  However, with the rain this weekend (yay!!!), maybe that will change.  My plants tend to bloom until the first hard freeze of winter.  The Coneflower has a winter rosette, so it acts as an evergreen ground cover, if planted in groups.  I like to plant them in groups of three to five, but I’ll let seedlings develop and happen where they will, because each individual plant isn’t that large.  My experience is that Purple Coneflowers complement other plants.  I’m not sure I’ve ever disliked the way they look in a mixed perennial garden–with reds, blues, yellows, whites–they’re a fabulous addition to the mixed perennial garden.

A couple of my  individual Coneflowers didn’t survive this summer–some of those were in blasting sun. As a group though, my plants weren’t adversely affected by the heat and drought this year, except for a shorter bloom cycle.   I’ve heard from other gardeners with  heavy clay soil that they don’t have much luck with Coneflowers.  And years ago, I gave my mother some seedlings to plant (in Corpus Christi, on sand) and hers didn’t do well either.  Coneflowers seem to flourish in moderately rich and well-drained soil.

Purple Coneflowers are endemic to North America and a great plant for any gardener who wants a showy, long-lasting and easy addition to the garden.

  1. I’m another gardener torn between having too few and too many. In the early summer I love them and then when they fade away they look pretty ratty. Torn between cutting back the heads and saving them for the birds. What I have found is that if you have some young ones they bloom much later so it is fairly easy to have a succession of new plants. I saw your roadrunner in among the blooms. I have the same one although he is not recognized by our real resident roadrunner. He just thinks it’s a piece of old metal.


    • Funny about the roadrunner! I bought one for a friend and liked it so much that I bought another for myself. I think you’re right about having a succession of coneflower blooms. I also learned from the “experiment” that I talked about, to plant coneflowers with shrubs and other things that will bloom once they’ve peaked. I do love them though–even when they look ratty.
