New hybrid coneflowers: How reliable are they?
The new hybrid coneflowers offer appealing colors and shapes, but some may not be as reliable in the garden as the old standby, Echinacea purpurea.
When you specialize in one particular plant, it’s easy to fall into a gardening rut.Skip to next paragraph

While living in Maryland, I focused on roses and companion plants that looked good with roses. I wasn’t very interested in experimenting with anything new.
Now that I’m starting over with a garden in the mountains of North Carolina, I see I’ve been missing out on some really interesting perennials. I inherited a few daylilies and am just beginning to appreciate their beauty and usefulness.
I was also intrigued when a coneflower popped up in an area where I’d sown wildflower seeds last summer. It was just an old fashioned Echinacea purpurea, but it looked quite elegant amid a group of oxeye daisies.
I wondered why I hadn’t noticed this appealing flower before.
The humble Echinacea has some fancy new cousins
Hardy, attractive and easy to grow, these popular American wildflowers have long been a staple of the perennial border both here and in Europe.
Beginning in the mid-1990s, a number of enterprising plant breeders began making crosses between several varieties of native coneflowers in an attempt to make a good thing even better.
The result is a dizzying array of new hybrids in a rainbow of delicious colors, along with a wide choice of flower forms (including pom-poms and doubles) and sizes from midget to statuesque.
Keeping up with all these new and unusual coneflowers is about as difficult as figuring out which of a multitude of rose introductions to try. The number of choices and names boggle the mind.
And once I decide on which of the new beauties to try, should I assume it will be as easy-care as the old standby?
The coneflower controversy
The traditional purple coneflower has been a Top 10 perennial for decades. It self-seeds so even when the original plant is just a memory, true seedlings will have taken its place.
Unfortunately, many of the new introductions don’t perform as dependably in the garden.
Many seem to disappear after a year or so, and others never bloom. Some fade quickly in the heat. A number of varieties don’t set seed and others produce strange seedlings.
