Six Plants That Will Make You Landscape Design Genius

There can be a tendency for landscape designers to have a set number of plant taxa in their design portfolio. The plants in the portfolio are reliable and perform, and they can be found at the local nursery or pickup yard, so they stick with the tried and true. The downside is that there is a good chance one's designs look a lot like everyone else's. 

Adding new and improved plants to your designs can set your designs apart and help you command higher margin jobs and clients. Plants that perform better and have multiple seasons of interest add greater value to a landscape or garden. Really good plants that exceed expectations can make you into a landscape design genius, particularly compared to the competition that does not keep up with the best plant materials. Here I have listed six outstanding plants that will make you stand out from the crowd. 


'Aphrodite'  Calycanthus 'Aphrodite' PP#24,014

Think of it as a red-flowered, dwarf magnolia that flowers from June until frost. It is a large shrub or small tree (6'-12'), so place it where it has room to shine. It is an excellent plant for making an informal flower hedge or for blocking unsightly views.  'Aphrodite' is a hybrid between our native sweet shrub and its Asian cousin. 






Double Take Eternal White®  Chaenomeles speciosa 'SMNCSDW' PP#35,018

A new, continuously flowering, thornless quince with big, double white flowers that provide visual impact even when the plant is in full leaf. This is the longest-blooming flowering quince on the market. Its large, doubled blooms appear in spring, and the show continues for months, often into early autumn. The delicious, camellia-like flowers open lime and then transition to pure white, and the dark green foliage adds the perfect contrast. This quince is a lower, wider-growing shrub than the other Double Take varieties, making it useful in many landscape areas.





'Sweet Summer Love' Clematis 'Sweet Summer Love' PP#24,044

Your clients will rave about your genius because 'Sweet Summer Love' clematis produces thousands of fragrant, red-violet blooms from mid-summer until fall, and its rich, cherry-vanilla fragrance is so delightfully intoxicating. So drape it over a trellis, fence, or post near an entrance door or a well-traveled path. Unlike Sweet Autumn clematis, this plant is seedless, aka non-invasive, so you'll never get unwanted seedlings. It is super healthy and does not get wilt disease or easily die off like many big-flowered clematis. The care is simple; just cut it back, like a perennial, to 1-2' each fall or early spring. That's it. Every summer your clients will remember you and your genius design!







Let's Dance Sky View® Hydrangea macrophylla × serrata 'SMNHSME' PP#34,327

Let's Dance Sky View hydrangea hybrid (H. macrophylla × serrata) is a standout for consistent, yearly blooming, whether you grow it in Michigan or Florida. Selected from our extensive Let's Dance hydrangea breeding program for its ability to not only conserve its old wood buds in the face of weather challenges but also its ability to continue creating new flowers. You'll also love how easy this cultivar is to turn blue, which is what I recommend since it’s so spectacular this way: flowers emerge a beautiful soft blue with a honeydew-green eye before maturing to a full sky blue. Its nice compact growing habit makes it both the front of the border, mass plantings, or as a container plant.  









Limelight Prime® Hydrangea paniculata 'SMNHPPH' PP#32,511

An improved, more refined Limelight with darker, healthier-looking foliage, stronger stems, and a more compact growth habit. The blooms emerge a vivid lime green and maintain that color longer, often until they transition into a bubblegum pink. The blooms eventually finish a rich, punch pink. You no longer get the sagging branches and chlorotic foliage you get with 'Limelight'.  






Double Play Doozie®  Spiraea x NCSX2' PP#30,953;

The first of its kind. A non-stop bloomer because it's sterile! The absence of seed makes it a noninvasive, perpetual bloomer that puts all of its energy into creating wave after wave of red-pink flowers from early summer through frost. No deadheading required! Foliage emerges in shades of red and lime green before maturing to a dark green. Double Play Doozie® spirea is incredibly low-maintenance and naturally grows as a neat mound but responds well to pruning if any shaping is desired. 







Bloomerang Ballet Syringa 'SMNSPH' PP#35,934 

Bloomerang Ballet® is the best pink reblooming lilac to date. Every year it puts on a remarkable show in both our Europe and N. America trial gardens. Who would have thought we could have fragrant lilacs that bloom like this beyond spring? It flowers in May, then takes a rest, and then blooms again from July until frost. Year after year, Bloomerangs provide nectar and pollen nearly all season long.







New and Better Plants in the Garden Center

It's mid-February, and the magnolias are starting to bloom in Alabama. It's hard to believe but spring is coming soon. The days are getting longer and the nursery catalogs are arriving so now is when people start thinking about what to add to their garden. 

If you are a professional landscape designer, you should be thinking about adding at least one new plant to your pallet. If you are a nurseryman, you should be thinking of even more. Just like iPhones and software, plants are always improving. 

On average, we introduce about 30 new woody plants a year. This is not set in stone; it just happens that we either found or developed that many when looking at thousands of trial plants. Today I'm going to introduce you to four excellent landscape plants. Let's get to it. 


GLOW STICK™ and GLOW BALL™ Ilex crenata



Glow Stick™ holly is a plant that adds both color and architecture to the garden. Like all Japanese holly, it does best in well-drained and slightly acidic soil. It can take full sun or partial shade, but you get the brightest color in full sun and it does not burn or scorch. What I love about his plant is that you never have to prune it. Growers do not need to space it. It adds season-long interest to the garden and contrasts nicely with mounded and horizontal plants. Hardy to zone 5b, it is perfect for small gardens, narrow beds, and in decorative containers. 



Glow Ball™ holly will also brighten up your landscape. It has the same cultural requirements but has a rounded habit. Shear it as you want it, into a ball or a low hedge. Again, the more sun you give it, the brighter it gets and there are no worries about scorching.


FIRE BALL SEEDLESS™ Euonymus alatus

This shrub is truly a game changer. Burningbush is one of the toughest and most useful landscape plants, but the species can be invasive. This seedless selection has solved this issue so we can now use it without worry. 

It has the fire engine red fall color people love and expect. It gets its best fall color in full sun and is adaptable to most any soil so long as it is not in standing water. It is a workhorse. 




KINTZLEY'S GHOST® Lonicera reticulata

The last plant I want to showcase today is Kintzley's Ghost Honeysuckle vine. While this plant is not new, it has been rediscovered and reintroduced to give it the spotlight it deserves.




This wild-looking plant is actually native to North America. Each season, it begins like any other honeysuckle, with typical dusty green leaves. As the season progresses, flower buds pop out like saucers. These rounded bracts look a lot like eucalyptus, but the flowers at the center feed native pollinators like hummingbirds! They turn into red berries in the fall, but won’t become a nuisance like other honeysuckles. Due to its size and interesting seasonal changes, it makes an incredible specimen.




Hardy from zone 4a to 8b, This easy-to-grow vine is adaptable and carefree. It is deer-resistant and attracts bees, butterflies, and hummingbirds. 

Come back soon. I will be featuring more new plants to make your landscapes the best they can be. 



When Trialing Roses You Have To Be Ruthless

I have managed large public rose gardens. I worked for a nursery that grew over  a million and a half bud and bloom, container roses per year. I have been an (AARS) All American Rose Selection judge. I specified roses as a landscape designer. So when it came time to develop a new line of roses, I knew that I had to be ruthless. I needed to create a testing system that separated the wheat from the chaff.


Fellows Riverside Gardens, Rose Garden in Youngstown, Ohio

When growing finished roses for a nursery, it became quite clear that the roses in two- and three-gallon pots had a limited shelf life. With each passing week, foliar diseases became a greater problem, even though we sprayed them with fungicides once a week. The daily overhead watering and the tight spacing were ideal conditions for black spot and mildew. So when developing our new trialing program, container trials with overhead watering were the first step, except we would not use any fungicides.


Greenhouse container trials with overhead watering and no fungicides

Ringo® Double Pink was a standout in our container trials.


As a rose garden manager, it was clear that over time a rose garden that is not rotated accumulates a bank of fungal spores that would infect our clean, newly planted bushes. The first year the roses looked fine, but in year two the disease took hold. That is why I do not rotate our rose trial beds. That is why we look at them for three years in the garden before we make any decisions about which plants to introduce. And of course we never use fungicides. 


Drone view of our trial garden 


Oso Easy® Double Pink was a clear winner in our garden trials.

We get trial roses from about five different breeders, and every one goes through this process. The odds are most selections will be trashed after two years. Any plant that shows disease is removed from the trail. Our goal is to throw them away as quickly as possible to make room for new selections. If I can find one rose variety out of a hundred that remains clean, looks good in the container and in the garden, flowers repeatedly, and is better than what's on the market, I am happy. Here are a few of my favorites that have passed the test and made our catalog.


At Last®—The fragrant blooms just keep on coming. 

At Last® rose combines all the romance of a fragrant, fully petaled tea rose with the no-nonsense practicality and vigor of a landscape rose. Enjoy a non-stop display of large, sweetly perfumed orange blossoms from late spring through frost. Handsome, glossy foliage and a vigorous, rounded habit make it ideal for use in the landscape or flower garden. Developed by Colin Horner of England.


Oso Easy® Double Pink creates a blanket of rich pink blooms.

Oso Easy® Double Pink - Excellent disease resistance and abundant, continuous blooms set this low-mounded, ground-covering rose apart from the crowd. Ten or more double flowers are produced per stem, creating a cheerful mass of rich pink all summer. Glossy, dark green leaves add to its appeal. Developed by Meilland International of France. It has gone on to win a Gold Medal in the Baden-Baden Rose trials, the ARS Best Shrub Rose in Ground Cover Form, and the Medaille d'Or in the Concours International trials in Nyon, France. 


Oso Easy Double Red has gone on to win over 10 trialing awards.


Oso Easy® Double Red - A floriferous rose with tulip-like double blooms. Dark, disease-resistant foliage and a sturdy, rounded habit. Flowers are held well above the foliage, providing a distinctive, showy look. Developed by Meilland International of France, this rose has already won ten awards, including the 2020 Rose of the Year, the Bagatelle Rose Trials 1st Prix, Prize of the Public and Certificat de Mérite; Le Roeulx Rose Trials Gold Medal; Lyon Rose Trials 1st Prize and Prize for Rebloom and Disease Resistance; Monza Rose Trials City of Monza Prize and Gold Medal, plus four others. This is a must-grow landscape rose. 


Oso Easy Enfuego™ is a warm rose that changes colors.

Oso Easy En Fuego® - A show-stopping new rose with all the bright colors and fun of a Mexican fiesta. Super clean, glossy, dark green leaves are the backdrop for nonstop blooms and fiery hues of yellow, orange, and red. If ever there was an impulse plant, this is it! Hardy and heat tolerant, it has been a standout performer in both Michigan and Florida trials. Another great plant hybridized by Chris Warner of the UK. 


Oso Easy Ice Bay® has super dark green and pure white flowers. 



Oso Easy Ice Bay® - “Simply beautiful” are the first words that will come to your mind when looking at this pure white rose. Incredibly effective in the landscape, its beauty lies in the simplicity of its flowers and their large, silky petals. Hardy and heat tolerant, this rose keeps its beautiful dark leaves and bright flowers until late autumn. While a single specimen of this special rose is enough to draw attention, it’s especially unforgettable as a mass planting. 


Oso Easy Peasy® is one of the very best, ground-covering landscape roses.

The 2024 Rose of the Year and the winner of the 2017 American Rose Society Award of Excellence in the No Spray division, this rugged beauty sends continuous sprays of vivid pink flowers from early summer through frost. Developed by the award-winning rose breeder, David Charles Zlesak. It is Easy Peasy!


Ringo® Double Pink is perhaps the best Persica hybrid to date


Ringo® Double Pink - Ringo roses glam up the garden! Developed with the extraordinary talent of the UK’s Chris Warner, this series provides disease resistance, durability, long bloom times, and the novelty of colorful flowers that not only sport a bright ring in their center but transform in tone as they age. Ringo Double Pink is a cheerful, pure pink rose with loads of semi-double flowers accented with bright yellow stamen surrounded by a distinctive wine-stained eye. More than just a pretty face, it is also very hardy, with glossy foliage that exhibits excellent black spot resistance. Winner of the First Class Certificate at the Hague Rose Trials. 


Rise Up Lilac Days® has a wonderful, intense fragrance.


Rise Up Lilac Days® - Breathe deep: the fragrance of this nearly thornless rambling climber is both alluring and enchanting. Waves of lovely lilac flowers arrive through the season in bouquet-like clusters. Perfect for scrambling up arches and fences. The romantic, semi-doubled flowers continue right up to frost, and its glossy, dark green foliage has shown superb black spot resistance. Great as a cut flower, as you can see below. Developed by the extraordinary talent Chris Warner of England. 


The End—thank you for visiting, and tell a friend.






PUFFER FISH® Hydrangea is a Winner

Make your landscape designs fun. PUFFER FISH® Hydrangea paniculata is like a BOBO® Hydrangea, but on steroids. Like Bobo, every inch of the plant is covered in billowy white blooms, but the plant is larger and the flower heads are much larger. It's so lovable, you will be compelled to hug it. Even as the white flowers age to green, new flowers continue to emerge at the tip. A bit like a fish statue spitting water into a fountain. Never floppy, the strong stems hold up the big blooms in the container and in the garden.


The output is:Three-gallon container of Puffer Fish hydrangea


In our Trial Garden

Note the size of the blooms.


This is the Hydrangea paniculata you want if you're looking for white. 


Note how the flowers keep emerging at the apex of the panicle.


The flowers age green without any pink.








Six Shrubs With Fantastic Fall Foliage

I would have thought, off the top of my head, that there were a lot of shrub species that had fantastic fall color, but when I drove our trial fields searching, I was dismayed that only a limited number of species really stood out with bright autumn hues. Of course everyone thinks of burning bush as the quintessential fall color shrub, but there has to be more. What else is there to use? 

With a bit of thought, I came up with a list of six outstanding shrubs that can add fantastic fall color to your landscape. They're in no particular order, but they're all excellent plants that are worthy of a place in your yard, nursery, or landscape design. Each has its own unique hue of fall foliage color, from blends of bright orange to bold purplish reds. And unlike Euonymus alatus, they're all North American natives. 

   

1. LEGEND OF THE FALL® Fothergilla


Fothergilla has always been appreciated for its spectacular autumn color, but Legend of the Fall® fothergilla sets a new standard for the species with brilliant, glowing hues of orange, yellow, and red. Spring brings a crop of fragrant white flowers. This plant was also selected for its improved production performance, a boon since this plant will surely be in high demand by landscapers and garden designers. 

USDA Zone 5-9 (-20°F/-28.9°C)

Exposure: Full sun, part sun
Height: 4 - 5'
Width: 4 - 5'
Bloom Time: Spring
Flower Color: White


2. LOW SCAPE MOUND® Aronia melanocarpa


As cute as a button yet tough as nails, Low Scape Mound® aronia is an innovative dwarf selection that may be the closest thing yet to a perfect landscape plant. Adaptable to most any soil, this versatile little black chokeberry offers dark, glossy foliage, loads of white flowers in spring, black summer fruit, and intense red foliage in autumn. Ideal for low-maintenance mass plantings; think of it as Rhus 'Gro Lo' with multi-season appeal. Developed by Dr. Mark Brand of the University of Connecticut. Low Scape Mound aronia is the 2019 Landscape Shrub of the Year. Winner of the Boskoop Royal Horticultural Society Silver Medal

USDA Zone 3-9 (-40°F/-40°C)

Exposure: Full sun, part sun
Height: 1 - 2'
Width: 2'
Bloom Time: Spring
Flower Color: White



3. KODIAK ORANGE®  Diervilla


Another eco-friendly alternative to burning bush, Kodiak® Orange diervilla pushes fall color to the limits with its transformation to fire embers orange. In the spring and summer, new growth emerges, a showy russet-orange, which is accompanied by bright yellow flowers in summer. But late summer and fall are the real show when the entire shrub turns bright citrus orange. This easy-growing, vigorous North American native is unbothered by pests or diseases. Diervilla is one of the most adaptable landscape plants you can grow. You'll find it growing in dry shade on the shores of Lake Superior, south on the red clay soils of Georgia. Sometimes known as bush honeysuckle, which is just plain stupid as well as a misnomer, so just call it diervilla as the common name. Developed by Garden Genetics, Kodiak Orange won the Boskoop Royal Horticultural Society Silver Medal. 

USDA Zone 4-7 (-30°F/-34°C)

Exposure: Full sun, part sun, shade
Height: 3 - 4'
Width: 3 - 4'
Bloom Time: Summer
Flower Color: Yellow
Foliage Color: Orange



4. SCENTLANDIA® Itea virginica 


Fabulously fragrant. Sweetspire is beloved for so many reasons: it’s native, shade-tolerant, deer-resistant, has handsome foliage, amazing fall color, very showy flowers, and, of course, delicious fragrance. So how could Scentlandia® sweetspire improve on the classic? Better hardiness and better fragrance. It has the best fragrance of any Itea I've ever encountered. Year after year you'll get great fall color, along with a compact, refined habit. Winner of the Boskoop Royal Horticultural Society Silver Medal. I named it in honor of one of my favorite TV shows. 

USDA Zone 5-9 (-20°F/-28.9°C)

Exposure: Full sun, part sun, shade
Height: 2 - 3'
Width: 2 - 3'
Bloom Time: Early summer
Flower Color: White
Foliage Color: Green



5. SKY DEW GOLD® Vaccinium corymbosum


Bright yellow foliage is the backdrop for tasty summer blueberries. Things get even more interesting as the summer nights start to cool and the golden foliage starts taking on rich hues of orange and red. The transformation is simply thrilling; seeing something so colorful and cheerful puts a smile on my face. 

USDA Zone 4 - 8 (-30°F/-34.4°C)

Exposure: Full sun
Height: 2 - 4'
Width: 3 - 4'
Bloom Time: Late spring
Flower Color: White
Foliage Color: Chartreuse, Orange



6. GATSBY PINK® Hydrangea quercifolia


Just as The Great Gatsby is a classic of American literature, H. quercifolia is a classic North American native hydrangea. Long prized by savvy gardeners for its flowers and fall color, this sophisticated shrub deserves a wider market. Gatsby Pink is a remarkable oakleaf selection from Powell Gardens of Kingsville, MO. It boasts big, showy lacecap blooms that quickly transform from pure white to a delightful pink. The dark green foliage turns mahogany-red in autumn. It also reblooms a bit as well. 

USDA Zone 5-9 (-20°F/-28.9°C)

Exposure: Full sun, part sun
Height: 6 - 8'
Width: 6 - 8'
Bloom Time: Summer
Flower Color: White, Pink
Foliage: Color: Green, burgundy 


7. STAGHORN SUMAC Rhus typhyna 



Ok, so I cheated and added a seventh shrub, but it is so worth it. Rhus typhina, the Staghorn sumac, is one of my favorite native shrubs because it is one of the first to change color. The plant has fuzzy stems (like a stag’s horn), great orange to deep red fall color, and attractive red seed heads. I learned this plant as a young boy when my dad taught me how to make staghorn lemonade with its fruit—look it up. It’s commonly found along highways, forming dense clumps. At 70 mph, it's easy to see that each clump differs genetically in size, fall color, and fruit. Unfortunately, as it is a suckering plant that moves around a bit, most gardeners don’t have the room for a clump in their garden. Still, it does deserve greater use. There are several excellent cultivars that are garden worthy; ‘Disecta,’ aka ‘Laciniata,’ is grown for its attractive lacy cut leaves. Tiger Eyes or ‘Bailtiger’, is a yellow leafed selection of ‘Disecta’. This plant has all the wonderful attributes of the species but with bright yellow leaves that give summer-long interest.
