Our Purple Coneflower - Little Echinacea on the Prairie.
By Johnny Caryopsis.
Mention the word “Echinacea” and most people will have heard it and know its association with herbal medicine. Echinacea in various forms is thought to be an immuno-stimulant helping people to ward off diseases of various sorts, especially colds and flus. But ask most people what Echinacea really is and where it comes from and you’ll probably get nothing more than blank stares. “Echinacea comes in a bottle”, is what you might hear. Yeah, and meat comes from the store in a plastic wrap on a styrofoam tray.
I recently read a report from Statistics Canada stating that, whereas in the 1930’s and 40’s one in three Canadians lived on a farm, now only one in 46 of us lives on a farm. The more our society “advances”, the further we get from the land and nature and knowing where stuff comes from. Echinacea comes from a plant, or rather it is a plant. Echinacea is the genus name for a group of North American wildflowers, called coneflowers, in the composite or Asteraceae family. They all have large, showy daisy-like flowers and they all contain chemical compounds thought to have medicinal value for people. In fact, coneflowers are so full of cool chemicals they are often said to be “pharmacological cornucopia” - try saying that fast three times!
Manitoba's Purple Coneflower in the wild: Click for pic.
Manitoba’s mixed grass prairies in the southwest of our province are home to one member of the coneflower family, Narrow-leaved Purple Coneflower (Echinacea angustifolia). I first came across these large, but straggly looking wildflowers in the Souris River Valley Wildlife Management Area, south of Brandon. As a wildflower they are not unattractive, but somehow, to me at least, they look a little rough and out of place; not exactly a delicate and graceful plant. And yet, Manitoba’s purple coneflower, though not ranked highest for beauty, is rated the best of all the coneflowers for its medicinal value. Another example of the hidden qualities of those that dwell on the northern prairies, we humans included.
Our purple coneflower is an important indicator species of good quality mixed grass prairie in this province. Sadly, both the coneflower and our prairies are dwindling rapidly. Mixed grass prairies are being plowed up to grow potatoes, overgrazed by cattle, buried under concrete and ashphalt, and covered over by human homes and lawns. Purple coneflowers, a plant we have only just begun to appreciate and explore for useful compounds may soon disappear from the wilds of Manitoba. We humans really are in danger of cutting off our noses to spite our faces. The planet can’t keep giving up species and wild places forever. We can only push the biosphere’s house of cards so far before it comes tumbling down.
So I keep writing about nature in Manitoba for NatureNorth, and hoping that I touch a few people with each article. And they in turn tell others and ultimately enough people can start caring enough about our natural heritage that we collectively act to protect what’s left. Sometimes, though, it feels like I’m writing an obituary of Manitoba’s natural heritage. I hope you’ll prove me wrong.
