Why Plant Native Plants?

WHY PLANT NATIVE PLANTS?

 

  1. Native Midwestern plants are sustainable.  They are well-suited to the climate and soil conditions of the area where they are found naturally–they are grown successfully with little effort.  They are adapted to extreme temperatures, blustery winds, and intense sunlight.   They are drought-resistant–once established, after 2-3 years, they need no supplementary water.  The roots of prairie plants grow deep into the earth–some as much as 15’ where water is available.  (The root systems make up 2/3 of the plants’ biomass).  In addition,  the surfaces of the leaves may be hairy, deflecting  sun and wind, or thick and leathery or waxy to minimize transpiration.  They do not need to be dead-headed or divided–they like to grow close together and  they seed themselves about, making them bountiful beyond belief.  They need no fertilizers nor pesticides.  The growing point of prairie plants is just below the surface, making them resistant to fire, unlike exotic species.  An annual controlled burn fertilizes the plants with its ash and keeps woody plants and Eurasian weeds  at bay.  Nothing needs to be brought in, nothing has to be taken out.  If native soil is no longer on the site, native plants wil create native soils.

2.  Native plants improve the soil and absorb and hold rainwater.  1/3 of  the dense root systems of prairie grasses and sedges  decompose every year, enriching the soil with organic matter and increasing its water-holding capacity.  The decomposed roots open channels for water to infiltrate into the soil and  replenish the shallow aquifer.  This water infiltration and holding capacity prevents runoff, erosion, and flooding.

3. Deep-rooted prairie plants have the ability to sink carbon--in the temperate zone where we live, grasslands are more efficient at absorbing carbon than are forests.  CRI’s Writings, Essays and Biological Monographs The Realities of CO2:Seeing through the Smog of Rhetoric and Politics Gerould Wilhelm

4.  Native plants support biodiversity by  providing food for native insects, that in turn are eaten by native birds–96% of birds eat insects.  Native landscapes and gardens provide habitat for birds, butterflies, bees, grasshoppers, crickets,and other insects; frogs, toads, and salamanders; and they offer fascinating places for children to play.

5. Native landscapes celebrate the character, history, and identity of a particular community and region.

    Some of the plants on display at Chelsea are English native plants or plants that have naturalized there. In England you see rhododendrons, digitalis and valerian (Centranthus ruber) growing wild in roadside ditches, for example. What’s “unnatural” about Chelsea is that many of the plants on display have been forced into bloom for the 3rd week of May. Imagine 50 different clematis, lilies or roses in full bloom at the same time. I once saw a tabletop display of perhaps 50 different alliums and I asked the presenter how he got them all to bloom at the same time. He replied “By growing 10 times more plants than you think you’ll need.” This was an indoor display under the tent. Then there are the outside gardens that are out of this world.

    Hi Pat, I love your reflection in the poster taking the picture. It’s very reflective of how passionate you are about natives. Thanks for all the lessons. Jean

      Thanks, Carolyn, for telling us about Chelseait must be gorgeous!

      Jean, I never noticed that before–you’re absolutely right. That is my reflection taking the photo–how clever of me! Thanks for pointing that out.

    Nice essay Pat. Thank you. Beauty is not only visual. A landscape also has auditory, olfactory, and tactile beauty. Most beautiful, though, as you relate is the functional, interrelated, co-evolved beauty of the ecosystem.

    You are a wonderful prairie ecosystem ambassador!

      Very eloquent, Mary. Thank you for commenting.

      Wonderfully stated Mary!
      Superbly presented Pat!

    So well described! Photos with commentary explain so much — thank you!

    Visiting the Chelsea Flower show is on my bucket list. Living in the Midwest, with our incredible natives, is an ongoing, visual feast. The pleasure of driving by the displays is doubled by knowing that so many other eco-services are happening there. A banquet for every pollinator, bird and insect in the area as well as our eyes.
    Thanks Pat

    Shall we count the reasons we should grow native Illinois plants? You’ve covered all of them, Pat, including one that is very quotable. “Native plants will make native soils”. Also, I didn’t know that Black Swallowtails like Joe Pye Weed. This blog might be one of my favorites.

    Well said!
