Gardens of France: American Cemetery at Normandy

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.

Little Bluestem Varieties

Schizachyrium scoparium, also known as little bluestem, is the official state grass of Kansas. And for good reason! It is found in every county of Kansas, produces an incredible amount of biomass per acre, and is host to nine species of skipper butterflies. No fertilizer or fuss required, it will grow well in harsh conditions and poor soil. Little bluestem is a great grass to add to your landscape if you want something ecologically beneficial, water-wise, and colorful.

Variety vs Species

Because it is such an impressive plant, little bluestem has gotten a lot of attention from the horticultural industry. Professional breeders have selected and cultivated many new varieties. Humans have been selecting and breeding desirable traits into plants for thousands of years, so we are getting quite good at it by now. Customers looking to buy little bluestem have a lot of options to choose from in terms of height, habit, and color palette. While they are all still S. scoparium, they all offer something different that might benefit a certain landscape use. Below is a comparison of several options and their traits to help you decide.

Little bluestem is known for its fine foliage and multitude of colors.

S. scoparium

The straight species, as we say, is the regular old wild type. S. scoparium that’s propagated by seed is genetically diverse from every other little bluestem growing around it. In contrast, most cultivated (named) varieties are propagated by division, meaning they are exact genetic copies of each other. This ensures the same coloration and habit. But if you don’t need that kind of aesthetic assurance, the classic little bluestem is a great option. You’d find this growing in prairies, pastures, and field edges. Pros: genetic diversity, great for restorations, wildlife areas or pastures, usually cheaper than branded varieties. Cons: floppy, not as colorful as other options, height is less predictable.

‘Jazz’ Little Bluestem

Foliage height: 1.5 to 2 ft
Total with bloom: 2.5 ft
One of the main differences between bluestem cultivars is height. ‘Jazz’ is a great solution for folks who want bluestem, but need it to be shorter than the regular species. A variety brought to market by Intrinsic Perennials, ‘Jazz’ usually stays under 24 inches and has a very bushy, upright habit. Pros: short, full and fluffy, upright. Cons: not as colorful as other options

Here you see two types of little bluestem in winter. ‘Jazz’ on the right, is shorter and fuller than the ‘Twilight Zone’ next to it. They also have subtle differences in color.

‘Twilight Zone’ Little Bluestem

Foliage height: 2 ft
Total with blooms: 4 ft
Known for its incredible coloration, ‘Twilight Zone’ is a fan favorite. Year after year we sell out of this one, and even our suppliers can’t keep it in stock. It has a powder blue coloration on the grass blades, followed by deep purple tips in fall. Mid-height, it is not as tidy and compact as Jazz but still stands up well with minimal floppiness given the right conditions. Pros: unbeatable blue color. Cons: too tall for some applications, may flop if partially shaded or in rich soil.

Adding lots of cool tones to the garden, ‘Twilight Zone’ works well with companion plants in purple, blue and yellow, such as Russian sage, gayfeather, golden Alexanders, and alliums. Photo courtesy Walters Gardens.

‘Blaze’ Little Bluestem

Foliage height: 2 ft
Total with blooms: 3 ft
If you like red, ‘Blaze’ is the choice. This variety is lush and green all summer, then packs a punch in fall with its deep red/orange/pink tones that delight all winter. ‘Blaze’ was actually bred as a high-yield pasture grass in the 1960s, but has been lauded for landscape use because of its beauty. ‘Blaze’ is especially nice in mass plantings. Pros: red fall and winter color, vigorous growth. Cons: flops easily if soil is too rich

I could go on and on about other favorites like ‘Standing Ovation’, ‘Prairie Blues’ and ‘Carousel’. No matter which little bluestem you choose, it will be a great low maintenance plant providing habitat and beauty all year long.

Reasons to Leave Ornamental Grasses In Winter

The use of ornamental grasses in the landscape has become more popular than ever, and for good reason. The allure of ornamental grasses is that they are tough and easy to grow. Their resilient nature reflects our prairie landscape in our own garden. They are a nice visual contrast to many other plants like perennials, shrubs, trees and even other grasses. A bonus is the beauty and movement they add to the winter landscape.

One of the questions we get this time of year is whether or not to cut ornamental grasses back to the ground for winter?

In the fall, ornamental grasses are in their full regalia with their attractive seed heads. From short to tall, these grasses put on quite a late season show. As we transition into fall, the colors they develop are another reason we use them in our landscapes. However, these fall colors fade and we are left with dull shades of tan and brown. Is it best to leave these grasses now or remove them? Generally, we leave them through the winter, and cut them back before they begin to grow next season. In Kansas, this task can be done in late February to early April.

Here are some of the advantages of leaving grasses for the winter and waiting until the spring to cut them back

  • Grasses provide form and texture in the stark winter landscape of withered perennials and deciduous shrubs. These qualities stand out in the frost or snow and low winter sunlight.
  • Mix well with perennial wildflower seed heads
  • Provide movement in the garden. The tawny stems and seed heads move with the gentlest breeze.
  • If used as a screen, they can be left up just before they start greening up again in the spring.
  • Most native grasses can provide habitat and shelter for birds and other small animals along with overwintering sites for insects and pollinators.
  • By waiting to remove the previous year’s growth until late winter, the crown of the grass is more protected from the elements.

How do I cut back my grasses?

After leaving the stalks up through the winter, they are drier, more brittle, and easier to cut back. I like to cut tall grasses like switchgrass and big bluestem down to about 2-3 inches off the ground. I do this with a hedgetrimmer by moving it back and forth across the stalks a few inches at a time. We used to completely remove these stalks and haul them away. Now, we let the clippings lay as mulch around the plants. These stalks may still have overwintering pollinators in the stalks that are left in the garden for next season. By spreading the cut stems around as mulch it helps to break down more quickly too. I shape smaller grasses like prairie dropseed with a pruner or hedgetrimmer. Again, I like to cut them back to two to three inches from the ground.

Over the years, we have found it very beneficial to leave ornamental grasses standing for the winter. You’ll be creating a habitat for birds, insects, and small animals. The rustling grasses will remind you of the successful season past and the promise of spring yet to come.

Native Grasses in the Garden

One of the more exciting trends in gardening today is the use of grasses, not for lawns, but as ornamental plants. Even though they do not have showy blooms, grasses can add graceful beauty to gardens and landscapes.

With long narrow leaves and upright habit of growth, grasses have a fine texture, which can provide interesting contrast to other plants in flower gardens.  They can also be used alone as accent plants in the landscape. Many grasses produce attractive seed clusters and have foliage that changes color at the end of the summer.  The dried foliage of grasses can be left standing through the winter, adding movement and texture to the landscape when garden flowers are dormant and tree branches bare.

Many of the grasses being used in landscaping today have their origins in Asia and Europe. There are a number of different grasses from our prairies, however, that also make excellent ornamental plants. These native grasses possess the added advantage of being well adapted to our soil and climate.

Big bluestem, indiangrass and switchgrass are three tallgrass prairie species that make attractive plants in the garden or landscape. Growing 4-6 feet in height, they can be used in flower beds and borders as screens and as accent plants.  Switchgrass is the most common of these added to landscape designs because of cultivars like ‘Northwind’, ‘Cheyenne Sky’ and ‘Totem Pole’, which offer consistent height and color year after year.

Like the leaves of certain trees, the foliage of these grasses also changes color with the onset of fall.  Big bluestem is particularly noted for its reddish fall color. Each of these species also produce distinctive seed clusters that add interest to the plant toward the end of the growing season. The seed clusters are shaped like a turkey’s foot.  Indiangrass produce attractive golden plumes.  Switchgrass seed cluster are open and feathery.

Sand lovegrass is another attractive taller species. It grows 3-4 feet tall and is found in sandy prairie areas.  It produces graceful arching foliage and open, airy seed heads.

Although found throughout much of the Great Plains, little bluestem and sideoats grama are two grasses that are particularly characteristic of the mixed grass prairie region of central Kansas. Both make beautiful additions to gardens and landscapes.

Little bluestem is a fine-textured, clump-forming grass that grows 2-3 feet tall.  Its landscape value is enhanced by its attractive reddish coloration late in the growing season. There are several selections that offer nice winter coloration and sturdy habit.

Sideoats grama is of similar height.  The most ornamental attribute of this grass is its beautiful seed clusters.  The seeds hang gracefully from one side of the seed stalk, giving the plant a windswept look, even when the air is still. The Sioux Indians called this plant “banner-waving-in-the-wind grass.”

Prairie Dropseed is a favorite of mine because it is long-lived and tough.  It is so tough, that they are often planted in mass in street medians.  The fine textured leaves and airy, fragrant panicles are a nice addition to any landscape.  Each clump can reach 12-18 inches wide and up to 24 inches tall.  The entire plant turns shades of orange and yellow in the fall, providing multiple seasons of interest.  It is great in a border, as a groundcover, in an informal prairie setting or as an accent to other short or mid-range perennials.

For people who live in prairie country, it may be easy to take our native grasses for granted. Yet these plants with their simple form and subtle beauty, can make attractive additions to the home landscape.

Five Grasses You Should Be Using In Your Landscape

I am always in search of the tough, resilient plants that stand out in any challenging landscape.  Certainly, ornamental grasses fit into this category.

They are increasing in popularity because of their texture, form/structure and interesting seed heads.  Another reason their popularity continues to grow is that they require minimal care and provide year-round interest.

Ornamental grasses are a diverse group of perennials that expand the plant palette of any design, but many of them get too tall for a typical landscape application.

This week, I wanted to make note of some of the dwarf grasses in our gardens.  As you know, fall is the best time of the year for most grasses.  They are showing off their attractive plumage and the beautiful fall colors are beginning to develop.  These five grasses have worked for me, and can be found next week at our Fall FloraKansas Plant Sale:

 


Blue Grama-Bouteloua gracillis ‘Blonde Ambition’         

This Blue Grama Grass is apparently on steroids.  I cannot believe how vigorously it grew this year, ultimately reaching two feet tall. This taller form has bright blue-green leaves that are topped by a host of eyelash-like golden yellow flowers.  They wave in the wind and ambitiously last from summer into the fall and winter months.  I used it along a walkway but it is so attractive that it could stand on its own providing many months of ornamental interest.   This beautiful grass was discovered by David Salmon of High Country Gardens.

Little Bluestem-Schizachyrium scoparium ‘Carousel’

At home in a formal planting or prairie garden, you don’t have to sacrifice anything by planting this Little Bluestem.  Carousel remains stiffly upright even through the winter.  The gentlest breeze puts the plant in motion.  The blue-green leaves are highlighted by pink that gradually turn to rich copper, pink, and mahogany tones in the fall.  It truly has a carousel of color.  It provides a beautiful backdrop to perennials like coneflowers or black-eyed susans. This graceful, low maintenance Little Bluestem will provide a form that can be used in any sunny landscape.   Other garden-worthy varieties of Little Bluestem are ‘Standing Ovation’, ‘Blaze’ and ‘Blue Heaven’

Carousel

 


Prairie Dropseed-Sporobolus heterolepis

At one time, this was the top selling native grass in the country.  To see a mass planting in full bloom, you can understand why it is so popular.  The narrow leaves form a perfect fountain of green.  In late summer, the fragrant airy seed heads develop.  Some liken the fragrance of the blooms to buttered popcorn.   With this plant, you can get your theater popcorn fix without all the calories.  It requires almost no maintenance once established.  Fall color is burnt orange and rivals Little Bluestem in mass plantings.  A shorter form of Prairie Dropseed worth trying is the variety ‘Tara’.

Switchgrass-Panicum virgatum ‘Cheyenne Sky’

WOW! This grass is spectacular this year.  They are totally saturated in reds and purples.  Most switchgrass varieties get four to five feet tall, but not ‘Cheyenne Sky’.  It forms an upright three foot clump.  The vibrant red color hues begin to develop in early summer followed by reddish flower clusters in August and September.  The leaves rustle with the slightest breeze and sway in the wind adding movement to the garden.  I use it in containers, groupings or as a specimen plant by itself.  It is a very versatile and beautiful grass.

Fountain Grass-Pennisetum ‘Little Bunny’

We have been thrilled with this miniature fountain grass.  It puts on a show during the summer when the tiny cream seed heads pop up over the cascading green leaves.  The seed heads resemble little bunny tails, hence the name.  We have found it to be a reliable performer in the perennial borders and  when planted in mass.  If you have limited with space, then this grass would be a great choice.
