When you
specialize in one particular plant, it’s easy to fall into a gardening rut.
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.

Should I
get a Milkshake and Tomato Soup? Or a Marmalade and Merlot?
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.
Raspberry Truffle |
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.
It’s a
disappointing result after a great deal of hype and high expectations.
Anecdotal
evidence also suggests that the success rate for certain new coneflowers may
depend on the region where they are grown.
Jeff
Dinslage of Nature Hills Nursery reports that Tomato Soup has been a star in
his Nebraska yard for several years despite being placed in the worst spot in
the garden. Kim’s Knee Hi is another variety that does well in the heartland.

And
compact Elton Knight has done well enough in Britain to be given the Award of
Garden Merit by the Royal Horticultural Society.
White Swan |
I don’t
know if my White Swan and Ruby Star will be winners
here in the North Carolina mountains, but I will certainly report if either one
rates a thumbs-up.
I hope to
hear more about Echinacea experiences in other areas of the country.
The explosion of
these unique and enticing plants is exciting news for gardeners.
But before we
all go coneflower crazy, we need to separate the dazzlers from the duds.
