Why Natives Matter: A Sense of Place

In the weeks leading up a virtual panel discussion that GNPS is sponsoring (and I’m moderating so I’m definitely thinking about it a lot), I’ve wanted to put in writing some of my thoughts on this topic. While there are several aspects to why native plants matter [in conserved areas and in our gardens]—and I expect the panel to touch on those: pollinators, birds, etc.—there is one aspect that doesn’t get the attention it deserves. 

It is the concept that native plants give ecoregions a sense of place.


Ecoregions are unique physiological areas and, at the state level, Georgia has five of them: Cumberland Plateau, Blue Ridge, Ridge and Valley, Piedmont, and Coastal Plain (the Coastal Plain can be further divided into the upper Southeastern Plains and the lower Southern Coastal Plain/Maritime). Each of these regions is home to hundreds of native plant species, from towering native oaks (Quercus) to small single-leaf native orchids like the crane-fly orchid (Tipularia discolor). While some plants span multiple ecoregions, others occur in such unique environments that they grow only in one.

How many of us love to travel to the North Georgia mountains in the spring to see trilliums, mountain laurel, and rhododendron? Who doesn’t smile when they arrive in South Georgia to see acres of saw palmetto dotted with towering cabbage palms or an expanse of wiregrass and longleaf pines? How about the waving sea oats and the beach morning glories on the dunes at the beach?

In landscaped areas, we’ve lost the concept of Georgia plants. As we walk around our neighborhoods, drive along roads with landscaped median strips, and pass through shopping and business areas, what plants are there? Knock-out roses, non-native juniper shrubs, Japanese azaleas, Loropetalum, waxleaf privet, crape myrtles, and Cryptomeria. Encase those in a wrapper of non-native annuals, elephant ears, purple fountain grass, and dyed mulch and you have a landscape that you can see repeated from Georgia to New Jersey, and—surprisingly—from the east coast to the west. A canned list of non-native shrubs, trees, and seasonal bloom annuals/perennials seems to be passed from one designer to another, fueled by big box stores and nurseries that churn out endless supplies of these plants.

Why not appreciate the natural beauty of our regions and use our native plants as the primary landscape plants? Instead of knock-out roses in sunny spots, how about native plants like: St. John’s wort shrubs (Hypericum), Fothergilla, dwarf wax myrtle, hollies, summersweet (Clethra), viburnums, beautyberry (Callicarpa americana), blueberries, Spiraea, buckeyes (Aesculus), shrub dogwoods (Cornus), and more. Might we have to change the way we design those spaces to fit some of these? Perhaps, but don’t let a challenge stop us!

I cringe when I see beautiful mountain homes landscaped with non-native plants like butterfly bush, rose of Sharon, and crape myrtle. They could be decorating their landscapes with gorgeous native rhododendrons, azaleas, and mountain laurel. Why take a beautiful area and make it look like everywhere else?

Virginia sweetspire (Itea virginica)

I love finding landscapes where oakleaf hydrangea (Hydrangea quercifolia), Virginia sweetspire (Itea virginica), and Fothergilla have been used in the design. How refreshing to see these “unusual” choices show up. I usually always pull over and admire them. Perennial choices like purple coneflowers (Echinacea), black-eyed Susans (Rudbeckia), and pink muhly grass (Muhlenbergia) get the most use when it comes to natives, from what I can see. The need for continuous-flowering plants is what often drives choices to non-natives, but thoughtful selection could solve that. How about a 50-50 mix of native and non-native to get us started? Of course, we should pick regionally appropriate choices as much as possible.

When you're thinking about what to plant in your garden, think about choosing the plants that make Georgia and the Southeast unique: native plants. They'll beautify your yard and contribute back to the bigger ecosystem around you while also showcasing more of the natural beauty of Georgia.

  2. Great idea love the article. My goal is to use as many attractive Native perennial plants and shrubs as possible. As i explore I'm surprise to find how many attractive native plants there are. Some are hard to source, like Mt. Laurel(Kalmia) for example.

  3. This is such a wonderful post. I always think of far away places and distant lands and all their beautiful vegetation, but when I think of Georgia, and more specifically Atlanta, I've inherited a list of plants that are "southern" but not actually American. Gardenia from Asian and Africa, Azaleas and Japanese Cherry trees, Wisteria and Mop head hydrangea from Japan. All beautiful and lush, but unproductive and "sterile." I really want to see a beautiful example of what a real Atlanta Garden could be. Maybe they're out there and hidden, but I hope more show up and become prominent parts of our culture.
