New Plants around the Grounds

Posted on November 20, 2024 by Katie Schmidt

I recently spoke at the Oklahoma Native Plant Network fall festival in Oklahoma City. They had a day full of speakers, including representatives from Tulsa Botanic Garden, the Xerces Society and Bat Conservation International. But the real treat of course was the plant market outside the presentation hall. So many great native treasures were available from local vendors, I couldn’t resist buying a few new plants. I was able to get a few hard-to-find species for installation on the Arboretum grounds. Keep an eye out for these beauties on your next visit.

Callicarpa americana var. lactea – White American Beautyberry

I didn’t even realize a naturally occurring white variety of beautyberry existed until I saw it being sold by Wild Things Nursery at the ONPN event. All the same lovely characteristics as its purple cousin – shade tolerant, pollinator friendly, bird attracting – but with striking white berries on arching stems. Marilyn, the owner of Wild Things Nursery said she collected the seed over twenty years ago down a shady dirt road in north western Arkansas. According to her they come true from seed reliably. Beautyberry are marginally edible, though not very tasty. Find these new additions in the back of the Compassionate Friends Garden near the hedgerow at the arboretum.

Hibiscus laevis – Halberd-leaf Rosemallow

Our pond has several lovely Hibiscus moscheutos thriving along its edge, and I am excited to add H. laevis to the mallow collection. This is a slightly taller species with narrow leaves, as the name implies, in the shape of a medieval sword. Native throughout the eastern half of the US, though much of its wetland habitat in the mid-Atlantic has been disturbed. Sadly, it is not as commonly found as it once was. I’ll be planting this on tip of the island, where there is some space on the banks thanks to our latest renovation. I found this at a great plant at a vendor called Duck Creek Farms from Mounds, Oklahoma.

Wisteria frutescens – American Wisteria

Anyone who has seen the opening scenes of Bridgerton house on Netflix’s hit show will recognize the pendulous purple blooms of Wiseria vine. But most of the Wisteria you see in media and in formal landscapes is the asian variety. Beautiful, but at a price: invasive in certain parts of the country and downright pushy in the garden, it needs diligent trimming to keep growth in check. But native W. frutescens is a great alternative to its exotic cousins, and with plenty of color to spare. I’ll plant this next spring near a leg of our new octagonal gazebo soon to be erected in the Birdwatch Garden.

Shop Til You Drop

In between shopping for the Arboretum, giving the keynote presentation of the festival, and networking with all the like-minded conservationists and plant peddlers, of course I also snagged a few things for my own landscape! I found blackfoot daisy (Melampodium leucanthum) for a hot, dry spot near my front sidewalk. I also found an adorable spineless cactus (possibly Optunia ellisiana?) to plant nearby. Here’s hoping these cuties fill in the rather inhospitable space between my purple prairie clover and creeping sedum.

If you are in the area, put ONPN’s fall festival on your radar for next year. It was a great time to learn about native plants and related topics in conservation. And you will never see me turn down an opportunity to buy plants and support small growers!

Messy Trees

Posted on November 6, 2024 by Scott Vogt

I love this time of year. Cool mornings and warm afternoons are a welcome break from the heat of summer. This time of year also reminds me that not all trees are the same. Some have beautiful fall colors of orange, red, yellow and purple while others shades of tan and brown. Once the leaves drop from the trees, the fruit stands out even more.

We also quickly realize that some trees are “messier” than others. Whether it is the leaves that drop, the fruit that drops or the sticks that litter the yard, trees are constantly dropping something. Sure, there is not a perfect tree that magically cleans up after itself, but there are some trees to avoid planting in certain locations within your landscape if you have a choice. Here is a list of trees to think twice about planting in your landscape.

Sweet Gum (Liquidamber styraciflua)

This ornamental tree is primarily grown for its brilliant fall color of oranges, reds, yellows and purples. It can be quite stunning, but it also produces copious amounts of spiky gum ball fruit. My in-laws had one of these growing in their front yard and it was a prolific fruit producer that they complained about every year. Like most messy trees, it has its place in the landscape, but not in a place where your grandchildren will be walking barefoot.

*Sweet gums have great fall color, but spiny fruit*

Catalpa (Catalpa speciosa)

The large heart shaped leaves of this native lowland tree along with the fluffy white blooms in the summer can be reasons to have this tree in your landscape. However, the long cigar shaped seed pods and thousands of catalpa caterpillars are major drawbacks. I have one of these trees in my yard in a low spot that has standing water when it rains. I can appreciate the blooms from a distance but in the fall, I do have to collect the large leaves so they don’t smother my lawn.

*Catalpa heart-shaped leaf with long cigar shape fruit pod*

Cottonwoods (Populus deltoides)

These trees are notorious for dropping sticks and debris throughout the year. The fluffy cotton clogs up air conditioner units and seedlings sprout up any place with constant moisture in the spring. They are also susceptible to many diseases and insect pests. As our state tree, their native habitat is along rivers, streams and ponds. Their roots are typically shallow, buckling sidewalks and driveways. My colleagues have been lobbying to cut one of these down that currently grows on the edge of our prairie.

Black Walnut (Juglans nigra)

This tree is often found along prairies, stream margins and fencerows. While native, you should avoid planting a black walnut along streets and driveways. The round, hard nuts will stain concrete and they are tripping hazards. The fruit and foliage can be quite pungent as well and the leaves are a favorite of walnut caterpillars. These pests can become so numerous that they will totally defoliate the tree. It also produces a toxic compound that can kill other plants you are trying to grow around and under its canopy. Leave it in the wild and go to it to collect the black walnut fruit if you like to eat them.

Oaks (Quercus sp.)

I hesitated including oaks in this list, but then I looked at my back deck, currently covered with tiny acorns. We value oaks for their long life, shade, hardiness, fall color (sometimes), and wildlife attraction to our yards. In fact over 900 species of winged insects rely on oaks for their life cycles, not to mention birds and other wildlife. If you plant one of these mighty oaks in your yard, just know that you have to take the good with the bad. In my case, the good far outweighs the bad.

*Pin oak acorns roll around my backyard like marbles, but at least the squirrels are happy.*

Ginkgo (Ginkgo biloba)

The ginkgo tree is a living fossil with distinct fan-like leaves. The beautiful yellow fall color and hardy disposition make it a much sought after street tree. However, there are male and female trees. The female trees produce a fruit that is both messy and smelly. Some liken the fruit smell to rotting flesh. If you really want a ginkgo in your landscape, seek out one of the many male varieties.

Other obvious trees to avoid

Bradford pear, mimosa, Goldenrain tree, silver maple, Norway maple, weeping willow, river birch, Siberian elm, tree of heaven, mulberry, black locust and Russian olive.

Choose Wisely

As I said earlier, there are no perfect trees. We view some trees as “messy” because they require us to repeatedly clean up the yard. Every tree drops something, but messy trees with stinky, messy fruit and large branches that can damage your house or pests are more problematic. If possible, do your research before planting so you know what to expect as the tree matures. To get good shade, you might have to put up with some messiness. If you are stuck with a messy tree, either embrace its faults by regularly cleaning up the mess or choose to have it removed.

As you know, trees in Kansas are a luxury, so think carefully before removing a mature tree. The downsides of a mature tree needs to far outweigh the upsides. In the case of my 60 year old oak trees that frame my backyard, I regularly pick up fallen branches and routinely blow off my deck and sidewalks of acorns and leaves. I have come to appreciate these trees because they attract so many different forms of wildlife, provide shade, and add to the diversity of my entire landscape.

Aromatic Aster

Posted on October 23, 2024 by Brad Guhr

One of my favorite prairie wildflower species has to be aromatic aster (Symphyotrichum oblongifolium). Aromatic asters are hardy, drought-tolerant forbs that bloom toward the end of the growing season. Their leaves have an herbal scent when crushed. Aster species are host plants for caterpillars of butterflies including painted ladies, pearl crescents, and silvery checkerspots as well as many species of moths. In the late summer and fall, aromatic aster flowers delight the human need for color and provide nectar for many insects, most notably, butterflies, bees, wasps, flies and beetles.

*Aromatic aster var. ‘Raydon’s Favorite’*

According to Mike Haddock at Kansas Wildflowers and Grasses, aromatic aster is found across almost the entire state of Kansas on dry, open prairies. In our Dyck Arboretum reconstructed prairie, aromatic aster (seed collected from the Smoky Hills ~30 miles north of Hesston) is just about finished flowering. Its purple hues popped a couple of weeks ago among the reddish-brown colors of senescing warm-season grasses.

A Star in the Prairie Garden

In our native plant gardens, aromatic aster is the star of a show that we have been looking forward to all growing season. Aromatic aster fills garden spaces between other plants nicely where its dense, low 1′-2′ foliage crowds out weeds and lends above-ground support to neighboring plants. But its late-season flowers are the main reason that this species is a dominant part of our featured Butterfly Garden.

*Educational signage in our Dyck Arboretum Butterfly Garden bed (line drawings by Lorna Harder)*

While I enjoy observing all prairie flowers throughout the growing season and the pollinators they attract, aromatic asters just seem to take the human entertainment value to a higher level. Given the high number of flowers on each plant and the lack of anything else blooming this time of the year, this species usually seems to put on the greatest show of the year as it plays host to a busy array of insect pollinators.

The two varieties of aromatic aster in our Butterfly Garden are ‘October Skies’ and ‘Raydon’s Favorite’. They bloom at different times and in nice succession for a long season of attracting pollinators. I seem to usually observe the former blooming from late September to mid October and the latter from mid October to early November.

*Comparison of aromatic aster varieties ‘Raydon’s Favorite’ on left and ‘October Skies’ on right (Photo by Janelle Flory Schrock)*

Whether I’m walking with elementary schoolers, college students or retired master gardeners, this Butterfly Garden spot on a sunny afternoon is always a regular stop. The flowering spectacle by aromatic aster in this time of the year is one of my favorite flower/pollinator interactions in the prairie garden.

When trying to capture the jaw-dropping wow factor of a landscape scene like the Flint Hills or a Kansas sunset, a photo or video never conveys the inspiring scene I want. Nevertheless, here is a video of the super busy pollinator scene I witnessed yesterday (10/22/24).

13 Butterfly Species Observed

The butterflies I observed nectaring on the flowers of aromatic aster var. ‘Raydon’s Favorite’ yesterday included the following species: checkered white, sachem, common checkered skipper, fiery skipper, dainty sulphur, clouded sulphur, orange sulphur, eastern tailed blue, common buckeye, monarch, pearl crescent, Melissa blue, and American lady (not all species were visible in the video). Various species of bees (audibly busy), flies, beetles and moths were also abundant.

Stop by and see our Butterfly Garden before the aromatic aster finishes its show in the next week or two. Better yet, add different varieties of aromatic aster to a sunny spot in your landscape where you can enjoy a similar show for years to come.

Think Pink

Posted on October 16, 2024 by Katie Schmidt

Muhly grass is in its prime this time of year, and all our regular visitors are asking about it. This native grass is unforgettable once you see it in bloom, and we are lucky to have multiple types growing on our grounds. Read on to find out which species is right for you!

Muhlenbergia capillaris – Muhly grass, Hair

Planted in the northwest corner of the Arboretum, our plot of muhly grass is in its third year. When first planted they are pretty thin and unimpressive, but once mature these grasses really put on a show, especially if planted in large groups. Vibrant pink seed heads appear in late summer and persist in a thick cloud of color all through fall. Extremely drought tolerant, they hardly need watering once established. They require excellent drainage, best planted in gritty soils, or on a slope.

*M. capillaris* is native to the southeastern US. Map by USDA plants database.

Muhlenbergia reverchonii – Seep Muhly

Usually smaller in stature, this grass is notably less stiff. While M. capillaris grows straight up, the graceful blades of seep muhly are arching and curled. It isn’t as deep in color, but still has a nice pink hue that is slightly more airy and light. Better for folks who prefer more neutral tones. This species has much more movement in the wind, and is softer to the touch. Something to think about when installing grasses around play areas or walkways!

**M. reverchonii** has a more limited range, found in the central regions of Oklahoma and Texas.

Muhly Grass cultivars

There have been some great options on the market for Muhly grass cultivars in recent years, including a variety of M. capillaris called ‘White Cloud’. It has all the allure of those wispy seed heads but in an ethereal white, a perfect pop for darker backdrops like brick or evergreens. At 4 ft tall it grows a bit taller than the pink types and can be used as a fluffy, neutral tone backdrop in the garden. Muhlenbergia ‘Undaunted’ is a well-loved cultivar of M. reverchonii. It’s weeping seed heads and open habit make it a great specimen plant for the perennial border.

*‘Undaunted’ is noted over the straight species for increased hardiness in norther zones and having a deeper panicle color at first flush. Photo courtesy Walter’s Gardens*

No matter which Muhly grass you choose, as long as you plant in full sun and well draining soil, you will surely be thrilled with its light texture and season-long interest. It is a water-wise plant with no major pest problems, but it does have few flaws: collapses easily in heavy snow, not very hardy in northern zones, and doesn’t always establish well when planted in fall. Keep those things in mind when considering adding this grass to your landscape. Look out for the spring update of the Native Plant Guide on our FloraKansas page to find out what species we will have available at our spring sale.

Right Rudbeckia, Right Place

Posted on October 4, 2024 by Katie Schmidt

Rudbeckia is a very recognizable flower. Its bright yellow blooms appear when summer reaches its peak, and flowers steadily through the hottest part of the summer when we all need it most. Also known as black eyed Susan (named after a romantic poem!) or sometimes as yellow coneflower, Rudbeckia is a variable genus with many garden worthy species. But they each want a little bit different environment, so be sure to put them in the right place!

Rudbeckia maxima – Giant Coneflower

R. maxima is a lesser known species native to the southern US, including Oklahoma and Texas. It averages about 6 feet tall in our area, but can be taller in moist, fertile soils. The flowers attract pollinators all through July, and through the winter a bevy of birds perch on the cones and eat the nutritious seeds. The foliage is striking: waxy and grey, resembling cabbage leaf. A wonderful vertical element to add to your landscape, with very sturdy stems and large blooms. It is a show piece in the garden! But it can easily be floppy if it gets too much shade or the soils are too rich. Situate it in strong sun and semi-dry soil, with dense grasses around it for support.

*These **R. maxima** are thriving on the dry side of our drainage ditch near the greenhouse. The cones were huge this year!*

Rudbeckia subtomentosa – Sweet Coneflower

Sweet coneflower is often found in moist sites, as seen here growing on the banks of the Arboretum pond. This plant can handle a bit of dry soil once established, but in general it likes moist sites. So try to plant it in a low spot or drainage area. The common name references the subtle sweet smell of the blooms. Less spready than other species of Rudbeckia, it pairs well in the garden with grasses like Panicum and other tall forbs like Eryngium yuccifolium. The petals can vary in length, and sometimes they are even rolled or ‘quilled’ as seen in the cultivar ‘Little Henry’.

Rudbeckia triloba – Brown Eyed Susan

Clouds of small yellow blooms on stiff, wiry stems appear in mid to late June on this easy to grow perennial. It readily self seeds, to the point of becoming an absolute menace in the garden! But if you have the space to let it run wild it is a pollinator-attracting powerhouse. It is best planted in an area that can be contained, either by mowing, burning or hemmed in by sidewalk/pavement. This species is native throughout most of the eastern half of the continental United States, and grows well in full to part sun and average to moist soil. The cultivated variety called ‘Prairie Glow’ flowers red with yellow tips. It is a seed strain from breeder David Cavagnaro introduced to the garden trade in 2003. Both the straight species and the cultivar are often available at FloraKansas.

**Rudbeckia missouriensis** blooming in the Gjerstad garden on the northwest side of the Arboretum.

And beyond these three, there are tons more to choose from! In a previous post, Scott talked a bit about R. missouriensis, R. hirta, R. lacinata, and R. fulgida, all great options for the habitat garden. All of these and more are usually available at our biannual FloraKansas event, so be sure to keep your eyes peeled for our updated plant list when it comes out.

Plums, Cherries, and Very Bitter Berries: A Prunus Profile

Posted on August 14, 2024 by Katie Schmidt

In honor of all the wild plums ripening right now, this week’s blog is all about the Prunus genus of plants. There are several common Prunus species found in Kansas. All are excellent choices for wildlife and habitat gardening, as they produce fruit and many are important caterpillar host plants.

Gee, What a Genus

Prunus is a group of plants known as a Genus. If you remember back to your high school biology days, that is the grouping just smaller than a plant family, but less specific than a species. This genus contains over four hundred different species within it, and many are economically important plants for humans, including cherry, apple, pear, peach, plums, apricot, and almond. Thank goodness this genus exists, as it contains all my favorite types of pie! It also contains four very common species in our area: sand cherry, choke cherry, American plum, and Chickasaw plum. Those are the species we are going to focus on in this post.

Sand Cherry

Height: 3′-6′
Full Sun
Average to dry soil, tolerant of clays

Prunus pumila is a tough-as-nails plant that adds a splash of fall color to the landscape. Hot southern exposures are no problem for sand cherry. Birds and bugs alike visit this plant throughout the growing season for its fruit and flowers. A naturally occuring variant, Prunus pumila var. besseyii, known as western sand cherry, tends to be wider than it is tall. A great choice for parking lots or street medians when you need vegetation to stay shorter than five feet. There are even lower growing varieties, like Prunus besseyii ‘Pawnee Buttes’ , which stays reliably short (under three feet) with a prostrate habit. Prunus pumila ‘Jade Parade’ is another low growing option, but its branches arch upward rather than snake on the ground like ‘Pawnee Buttes’, better to show off its spring flowers. Edible fruits can be harvested for pies, jams, and all manner of sauces.

Chickasaw Plum

Height: 5′-7′
Full Sun to Part Sun
Average to dry, sandy soil

Also known as sandhill plum, Prunus angustifolia grows best in sandy soils but is highly adaptable and can be found all throughout the state. Showy white flowers in April give way to sweet and tangy fruits by July. The fruits are used to make wine and jellies. This is a great plant for stabilizing soil and preventing erosion, or for filling in hedgerows. It suckers quickly, creating dense thickets useful to small birds. Many of us Kansans have fond memories of picking these in childhood, careful to avoid the spiny branches, and toting a bucket of them back to Grandma’s house for processing.

Chokecherry

Height: 8′-10′
Part Sun
Average to moist soil

Pendulous white blooms in spring cover this small tree in April, attracting every insect in the area. It is a handsome landscape plane, thought it suckers aggressively in certain settings. The fruit of Prunus virginiana is beloved by birds, but not as well loved by humans. It has an incredibly astringent taste that basically chokes you, hence its name. Thanks to all those tannins, it takes a lot of sugar to make a yummy jam out of this but it can be done! Be sure to process and pit them correctly, as like most Prunus species, the pits/stems/leaves all contain cyanide-producing compounds.

American Plum

*Photo by: Matt Lavin from Bozeman, Montana, USA, CC BY-SA 2.0 https://creativecommons.org/licenses/by-sa/2.0, via Wikimedia Commons*

Height: 6′ to 12′
Full Sun to Part Sun
Average soil

Prunus americana is a delicious treat to find while out on a hike or walking in the pasture. Ripening in late summer, the fruits turn reddish orange when ready. They make for a fantastic jam, and can be used in desserts or turned into an applesauce-like consistency as a sauce for pork or venison. The tree itself is petite and ornamental, with white spring flowers that feed the bees.

Prunus, and We Will Grow!

The species mentioned here are relatively easy care and don’t take much special treatment. Many Prunus species will sucker, sending up shoots from the base of the plant and spreading to form a colony. You can either trim them off as they arise, plant in an area you can mow around to control the spread, try to find sucker-free varieties of your favorites, or simply plant them in an area that allows them to grow wild and free. Birds love the thicket-forming quality of these plants, and the less pruning you do the more cover they have to play around in! Trim out dead wood as it arises, and in the case of Prunus americana, trim in late winter and remove any dead wood promptly to encourage healthy fruit production.

If you are looking for a plant to add some high quality native habitat to your landscape, look no further than a member of the Prunus genus. They all have great ornamental appeal and high scores for their wildlife value. And many will be available at our upcoming FloraKansas event September 5-8!

Plant Spotlight: Spigelia marilandica

Posted on July 17, 2024 by Katie Schmidt

Bright red, versatile, compact habit and attracts hummingbirds…why has the landscaping industry so often overlooked this plant? Spigelia is a lesser known and underutilized species for native gardens. We rarely see it in landscape designs in this area, and it can be hard to find commercially available. What gives? Read on to find out about this wonderful plant and how to use it in your garden.

*Photo by J. Carmichael (Tevonic), Public domain, via Wikimedia Commons*

Pinkroot

Spigelia marilandica, also known as woodland pinkroot or Indian pink, is a petite treat. Two feet tall and wide and blooming in June, it is a big show in a small package. The deep red trumpet shaped blooms are yellow on the inside, forming a two-toned flower when the petals bend outwards. Indigenous people in its native range have used it medicinally, though we don’t suggest trying this on your own as it does have some toxic properties at higher doses.

*USGS Bee Inventory and Monitoring Lab from Beltsville, Maryland, USA, Public domain, via Wikimedia Commons*

The tube shaped blooms attract butterflies and hummingbirds, and it is low maintenance once established, needing no special trimming or care. According to its entry on the Ladybird Johnson database, “This plant does very well in gardens. It blooms from the bottom upward and the flowering season can be prolonged by removing the flowers as they wither.”

So, What’s the Catch?

S. marilandica is not found much around here. Its native range is mostly in our neighboring states to the south and east. Not to say there aren’t going to be a few stray specimens living in some moist woods of eastern and south eastern Kansas, but it would be rare. It likes lots of moisture, like streambanks and seasonally wet ravines, and prefers shade. Moisture and shade are not what Kansas is known for.

*This map shows the native range of **Spigelia marilandica**, from BiotaNA*

But if you have a shade garden in Kansas, you are likely giving it a bit of supplemental watering just to keep things going during our droughty summers. Why not add this beauty to the mix? They are difficult to find and propagate from seed (though there is some helpful advice here on that topic), but lucky for our local readers we will have some live plants available at our fall FloraKansas fundraiser! We will have a variety called ‘Little Red Head’,

*Spigelia ‘Little Red Head’, Photo courtesy of Walter’s Gardens*

Companion Plants

With its bright red color, Spigelia is a showstopper. But that doesn’t mean it can’t be complemented by companion plants that also like semi-moist shade. Think hostas, phlox, geranium, and starry champion. Spring blooming woodland ephemerals like Columbine and Mertensia would play well with this species. Remember to plant in clusters of three or five for the biggest impact, and repeat those clusters to create a cohesive look even if you are aiming for a naturalistic woodland garden.

Spigelia will be available at our fall FloraKansas event, which is coming right up in September, the weekend following Labor Day!

Early May Blooms at the Arboretum

Posted on May 7, 2024 by Scott Vogt

As we work further into spring, I thought I would share some rare and some common prairie plants in bloom at the Arboretum the first week of May. Enjoy!

Plains wild indigo *(Baptisia bracteata*)

Missouri evening primrose (*Oenothera macrocarpa*)

Native Blue False Indigo-*Baptisia australis var. minor* and Golden Alexander-*Zizia aurea*

Eastern Gama Grass-*Tripsacum dactyloides* reestablishing itself along the new concrete pathway in the Prairie Window Project south of the hedgerow.

We have been fortunate to receive just enough rain to green up the prairie nicely. If you are in the area, stop by and see the many other early May blooms. The Arboretum will be at its peak for spring bloom in a couple weeks.

Gardens of France: American Cemetery at Normandy

Posted on March 6, 2024 by Katie Schmidt

When most people visit Normandy, they aren’t coming for the gardens. World War II historians flock here from all over the world to learn, explore, and pay tribute to the thousands who died here liberating France, and later freeing Europe. I personally love this area of France. It is my favorite by far, not only for its history, but for its beautiful, rugged landscape and friendly people. (And did I mention Normandy is the home of Camembert cheese?)

Of course, no trip to Normandy would be complete without a stop at the American Cemetery and Memorial. And though we aren’t always looking for great garden design, sometimes I can’t help but notice!

Design That Sets the Tone

This is a garden bed at the entrance to the Normandy American Cemetery and Memorial. It surprised me! Modern and understated, blending so well into the blocky, simplistic design of the memorial I almost walked right past it. It is made up of two species: likely Calamagrostis ‘Karl Forrester’ and Gaura lindheimeri, also known as white beeblossom.

This is a perfect example of matching the tone of the place to the design. At such a somber site, it might feel strange to have anything too colorful, jazzy, or disorganized. Instead, the grasses stand tall and stately, the Gaura wispy and low. The combination is perfect here, and when a bit of wind comes through them the planting has wonderful movement, and an ethereal quality. If a garden could whisper, this one would.

Ornamental Grasses

I spotted some familiar North American native grasses as I explored the well kept grounds. Through the memorial and onto the walkway to the cemetery, there is a border of switchgrass and fountaingrass. This combination was repeated multiple times along the way, softening the edges of the walkway – pink and pillowy, and always in motion thanks to the sea winds off the beach. The shrubs and trees behind created a three tiered border – making the walk feel a bit enclosed and sheltered from the otherwise open plain. After a tearful trip through the memorial hall and museum, it is a lovely feeling to be ushered along by this soft texture and gentle swaying movement, mimicking the waves on the beach.

Beauty in the Margins

In Normandy, even the parking lots are beautiful! I was impressed by the city planning. In the many small towns in the area around the beaches, there was an effort to create greenspace at every opportunity. Instead of bare, sparse plantings dominated by mulch we are used to seeing in parking lot islands, I encountered lush shrubs and thickly planted perennials. This is simply a choice of good design — choose plants that thrive under harsh conditions, plant thick enough that weeds cannot get through, and stick to mass plantings for the greatest effect.

Landscape vs Landscaping

The genius of the plantings in this region was that they seemed to blend right into the surrounding rural landscape. I can’t be sure whether the plants used were always native to the area or just well adapted ornamentals. But regardless, great care was taken to blend and match the natural shapes and textures of the seaside climate. Sometimes with grasses that bring to mind sandy hues and beach waves. Or even by using dense shrubs planted in layers, to mimic the famous hedgerows of the area. We can bring this lesson back home by taking careful note of the common shapes, colors, and textures in the natural landscape of our area. Using that, we can recreate those things in our residential landscaping on a smaller scale. It is an abstract way of designing, but the pay off is a garden that feels balanced and very much at home.

Gardens of France: Seaside Plants of St. Malo

Posted on February 28, 2024 by Katie Schmidt

St. Malo is known as the corsair city; a place of pirates and lighthouses, rocky islands and medieval walls. Besides great history (and excellent pastry!), a botany-minded visitor in St. Malo can enjoy sightings of lichen, ferns, algae, and more. We did not visit one of the “gardens of France” in a traditional sense, but the plants of the city spoke for themselves, needing no formal planting or ornamentation. This was my second visit to the charming town, and because we got to spend several days here lazily walking the ramparts and beaches, I had plenty of time to admire all the plant life!

*View from the Ramparts looking out into the English Channel.*

St. Malo has fascinating history that includes Roman occupation, British invasion, pirates, and total bombardment and destruction in World War II; it has been a busy place! There is even a Netflix series out now based on the Pulitzer Prize winning book All the Light We Cannot See by Anthony Doerr, set in St. Malo. The best way to learn all this history is to head immediately to the ramparts that surround the city. These are 20 meter thick walls that were first constructed in the 12th century. The ramparts contain armory platforms for cannons to fire out at unwelcome ships, and below, seawater-soaked kennels formerly (from 1155 to 1770) used for housing rather vicious dogs that enforced curfew.

My travel companion had to put up with constant stops for plant photos!

Plants and Place

We didn’t visit any botanical gardens while here, but opted to admire the natural landscapes instead. In modern cities we think of plants a bit like infrastructure – something to be built up, planned for, and placed “just so” for a specific use. We call this greenspace. But in a seaside town like St. Malo, there are plenty of wonderful unplanned “plant moments” around every corner: ferns growing on the stone walls, intrepid xeric species sprouting up along the rampart edges, and salt-tolerant wildflowers on the nearby islands, just a short walk away at low tide. The plants allowed to grow in situ certainly give the city an old world charm. Why, in our modern American landscapes, are we so quick to weed whack and spray every little plant that sprouts up in an unexpected place? Maybe we are a bit overzealous in our management techniques, and we could aim to coexist with the native plants in our surroundings instead of control and prescribe.

Favorites and Substitutes for our Region

I loved these plants and want to plunk them into my landscape if possible. But I know my home climate is not suitable. I can, however, achieve a similar look using plants native and/or adaptable to our area, which is easier for me and better for pollinators and wildlife.

Echium vulgare was a favorite of mine, spotted on the top of Grand Bé island. Its upright purple spike reminded me of Liatris of the prairie, but their iridescent quality and bloom shape set it apart. Echium amoneum, known as red feathers, is a related species and grows extremely well in our dry, limey soil. The adorable and dainty yellow Diplotaxis I saw growing along the sidewalks could be replicated with our native Coreopsis palmata. Rock Samphire (Crithmum maritimum) looked so similar to garden sedum in shape and habit, which thrives in our area. All of these plants will be available at our spring FloraKansas event, so I will have my chance to recreate, in a small way, the shapes and textures of this wonderful place.

Unsolved Mystery

This wonderful silvery shrub seen above is still a mystery to me. I can’t pin it down, and neither can my plant identification apps! It was planted in well maintained hedges as well as growing in small town square gardens and bordering rock walls. Possibly in the mint family based on its squarish stems and resemblance to the annual plant known as dusty miller. Perhaps it belongs in the Scenicio genus? Those yellow flowers make me think yes, but I want to hear what you all think it is! Shoot us an email if you have any clues. In the meantime, I will use species like Perovskia atriplicifolia (Russian sage), Stachys byzantina (lambs ear) and our native Ericameria nauseosa (rubber rabbitbrush) to mimic that wonderful silver tone in my own garden.
