Enriching your Native Landscape

When we southeastern US homeowners release ourselves from the notion of a rigidly controlled landscape, magic happens. Instead of spending time shearing defenseless evergreen azaleas and boxwoods into cubes and spheres, or pouring chemicals onto a non-native lawn that you must then mow and fuss over, you can devote your energy to enriching your home landscape with native plants adapted to our region.

Not only will your blood pressure drop as diverse native shrubs, trees, wildflowers, ferns, and vines adorn areas once reserved for sterile sod carpets, our native wildlife — birds, insects, mammals, amphibians, and reptiles — will gratefully seek shelter and food in the havens you create. Suddenly, your home landscape not only contains beautiful and relaxing plants, it is also animated by native wildlife — a win-win for all.

After you’ve adjusted your thinking about your home landscape to embrace native species, myriad options unfold before you. The purists can plant unhybridized specimens of a plant. These species will be identical to the native vegetation that naturally occurs (where it hasn’t been obliterated) in our region.

For a little more wow factor in your home landscape, many, many wonderful varieties of our native species — called cultivars — have been developed by horticulturalists and are sold at most nurseries. For example, my spectacular specimens of Magnolia — ‘Elizabeth‘ and ‘Butterflies‘ — are both cultivars of our native Magnolia acuminata.

As all gardeners know, creating a landscape is a long-term endeavor. Unlike redecorating the interior of your house, when you implement a landscape design of any kind, you must factor time into the equation. Plants are alive; they start small and grow larger. Weather, disease, and animal predation affect how they grow and whether they flourish. But in my 45+ years of gardening experience in this region, I have learned that if I plant a landscape dominated by a diverse array of well-sited natives, year-round, breath-taking beauty is my reward.

Spring wildflowers like this Trillium start the prolonged display of beautiful natives in my landscape.

Autumn is almost upon us, which means now is the time to review your landscape plans, so that you will be ready for the fall plant sales that abound in our region this time of year. Perennials, shrubs, and trees are all best planted during the fall and early winter in our region, because the cooler temperatures encourage root growth, thereby better preparing your new additions for summer heat waves next year.

In central North Carolina where I live, the plant sale I get excited about is the North Carolina Botanical Garden’s Fall Plant Sale. The sale is an annual tradition at this Chapel Hill, NC public garden, and the array of healthy native plants available increases every year.

This year, among their many offerings, are two species of Pipevines — Wooly Dutchman’s-pipe (Aristolochia tomentosa) and Pipevine (Aristolochia macrophylla).  These shade-loving vines with heart-shaped leaves add vertical interest to a naturalistic landscape, and they produce interesting little flowers that really do resemble tiny pipes. My fanciful brain imagines elves smoking them beneath the abundant fairy rings of toadstools populating my yard.

But I plant this vine mostly because it is the only larval food source for Pipevine Swallowtail butterflies. This is one of our more spectacular large native butterflies, but we don’t see it much in the Piedmont region, because its larval food sources (what the caterpillars eat) are not widely available.

Yes, this means that if you succeed in persuading Pipevine Swallowtails to lay eggs on your Pipevines, the caterpillars will eat holes in the leaves. But these vines are vigorous and perennial. New vines will sprout from the roots the next spring. For my money, a few ragged Pipevine leaves are a small price to pay for seeing Pipevine Swallowtails visiting the nectar-rich flowers I grow nearby.

Creating a rich, diverse native landscape is like choreographing a ballet. Shapes, colors, and forms interweave in a complex dance that differs daily, promising always to entertain and engage observers while feeding and sheltering the dancers.

Consider buying some Milkweeds (Asclepias spp.), the only food their  caterpillars eat.

So, my fellow green-thumbed choreographers, now is the time to patronize your favorite plant sales, preferably first at your local public gardens that use sales proceeds to keep their garden gates open to the public. And if you live within driving distance of Chapel Hill, NC, pencil in a visit to the NC Botanical Garden’s Fall Plant Sale on September 26 (members-only night) or September 27. Options will be numerous; truly there will be plants to suit any growing condition your home landscape may possess. I’ll hope to see some of you there!

September means bugs and plant sales

This past weekend, I was able to persuade Wonder Spouse, Ace Photographer, to join me in a walk around the yard. He took just over 200 pictures, and he’s still post-processing most of them. But he released a few finished shots to me now, so that I could show them off.

As the leaves begin to color up and tumble from the trees, the insects and spiders in our yard seem to accelerate their activities. Flowers buzz audibly as the diversity of busy pollinators gather as much pollen as they can before winter stops them cold.

As I mentioned in my previous post, the spiders seem to get especially busy now. Orb weavers in particular erect massive webs between trees big enough, I imagine, to snag small birds. Not that I’ve ever seen a bird trapped in a web, but I do wonder sometimes.

The Writing Spider I showed you before now has a name — Big Girl — BG to her friends. She has grown enormous feasting on butterflies. Their discarded wings litter the ground beneath her sizable web. Last week, I watched the tiny male move his mini-web ever closer to the object of his fancy. I think he must have succeeded in his quest, because now he’s gone, and BG is distinctly fatter — full of fertilized eggs, I imagine.

Wonder Spouse took such amazing photos of BG that I must show you all three views:

We are fortunate in the southeastern Piedmont to have a wealth of autumn-blooming wildflowers. And this year’s uncharacteristically generous rainfall is making for especially widespread and colorful displays. Our floodplain is full of the red spires of Cardinal Flowers, numerous yellow composites, goldenrods, Monkey Flowers, and Blue Mistflowers. Wonder Spouse’s shots of the Monkey Flowers are still being processed, but here are a few photos to give you an idea.

My Green-headed Coneflowers have gone nuts this year. If you’ve got room for a 4-5-foot tall wildflower in your landscape, I highly recommend this one.

As the humidity levels begin to drop and the mornings grow cool and filled with cricket song, my mind turns to fall planting season. In my region, fall is the best time to plant most perennials and all woody trees and shrubs. Our usually prolonged falls give new plants plenty of time to focus on root growth before the ground freezes — if it ever freezes at all.

Most years, our Septembers are still hot and very dry, so I’ve tended to wait until October to plant new additions. However, this year, the ground has remained blessedly moist all season, and the heat has remained astonishingly bearable — no 100-degree temperatures at all (knock wood).

Thus, I feel comfortable encouraging my Piedmont readers to go ahead and start getting serious about fall planting. Local plant nurseries will all be advertising sales soon, but there’s one sale North Carolina Piedmont gardeners should be sure to put on their calendars now: The NC Botanical Garden’s Annual Fall Plant Sale. Members get first pick from 5:00-7:00 p.m. on Friday, September 27. The general public is welcome the next day, Saturday, September 28 from 9:00 a.m. to noon.

Bring your own trays or boxes to carry home your purchases, and if you’re like me, only bring as much money as you can afford to spend. The wide array of vigorous native flowers, trees, and shrubs is more than most avid gardeners can resist.

I am a firm believer that there’s always room for more special plants in a landscape. Now is the time to survey your yard for spots crying out for color or shade or scent — or all three! Go forth, survey your yard. Then acquire the new plants that will help you realize your dream landscape.

These yellow sunflower-family members have a faint sweet scent that seems to draw  a diverse array of pollinators.

Sweet dreams, avid gardeners!

A Great Time to Go Native: Fall Plant Sale at the NC Botanical Garden

You can never go wrong with Purple Coneflowers.

Those of us living in the southeastern United States hear the refrain every year: fall is for planting. Truer words were never uttered. In our hot, humid, often droughty summers, plants do well to survive at all. Spring planting of new trees, shrubs, and perennials is a huge gamble, even if you water during droughts. Spring-planted plants just don’t have big enough root systems to withstand all that our summers often throw at them.

Swamp Milkweed is a food plant for Monarch caterpillars and a nectar source for many butterfly species, including this Spicebush Swallowtail.

However, as the cooler, usually wetter weather of autumn arrives, new plants can focus on root growth while soils are still warm but not desert dry. Native deciduous trees, shrubs, and perennials do especially well at establishing themselves when fall-planted, because they can devote all their energy to root growth after leaf fall.

Mid-summer blooms of Buttonbush lighten shady moist spots in your landscape, and provide nectar for pollinators, and seeds for wood ducks.

You’d be hard-pressed to find a better selection of native trees, shrubs, and perennials than you will find at the NC Botanical Garden’s annual Fall Plant Sale. Members get first crack at the goodies on Friday, Sept. 14 from 5:00-7:00 p.m. — and a 10% discount! If you’re not a member, you can join that evening and use your discount immediately. The public gets their chance at the plants the next day, Saturday, Sept. 15, from 9:00 a.m. to noon. Bring your own flats or boxes to use to carry your purchases home.

Umbrella Magnolia offers gorgeous flowers, dramatic leaves that turn tobacco gold in fall, and these scarlet seed cones before the leaves turn — a native showstopper!

Why go native? If you’re a reader of this blog, you’ve read my reasons more than once. To summarize:

  • Native plants are adapted to our region, so they are better able to withstand our droughts, wet spells, heat waves, and occasional ice storms.
  • Native plants are food sources for native wildlife. As urbanization continues to eradicate our region’s native forests and fields, planted natives in home landscapes, parks, etc. help to keep our native wildlife alive.
  • Native wildflowers especially are key to maintaining our native pollinators. Now that honeybees (not native) are under attack by diseases and other issues, native pollinators are becoming increasingly critical to farmers who need their crops pollinated. Nobody eats if the food crops don’t get pollinated.
  • Native plants in our landscapes remind us of where we are, affirming our sense of place. Certain trees, shrubs, wildflowers, and ferns evolved here; they belong here, as do the insects, reptiles, mammals, and birds that evolved along with their native food sources.

The berries of this native Viburnum are devoured by birds as soon as they ripen in mid-summer.

We are all in this together, whether we realize it or not. Going native is your easiest gardening choice, and it’s your wisest. This fall, please consider adding some native plants to your landscape.

And if you live anywhere near Chapel Hill, North Carolina, plan to visit the NC Botanical Garden’s Fall Plant Sale. All proceeds support this wonderful public garden, so every purchase is a win for all who love the natives of this region.

Our native deciduous azaleas are usually overlooked by deer, and offer bloom colors that the evergreen non-natives cannot match.
