Are your summer container gardens in need of a fall makeover? Good news! There are many fall-flavored plants that will provide you with texture, form, and long-lasting colors in both flowers and foliage.

I love the combination of purple or blue asters (Symphyotrichum) with ornamental kale as the colors play off each other nicely for a long-lasting fall container. Using other lesser-known plants, such as some of the fall-blooming Salvias or sage can add height and lend to very interesting combinations in your container gardens. Try using cold-hardy vegetables and adding herbs to create interest and texture to any combination. I like using Swiss chard, broccoli, Asian greens, parsley, and onions (Allium) for interesting and colorful effects.

Fall Containers

Here are a few tips for planning your fall containers:

  1. To achieve a fuller effect, use more plants than you would in the spring or summer. As the days begin to get shorter and the nights get cooler, plant growth is slowing down or ceasing. By planting a fuller container, you will see immediate results that can last for the remainder of the fall season.
  2. Try to plant by early September to give your plants a chance to kick in with some growth before the cooler temperatures and shorter days slow things down. Remember, many plants available for fall container gardens can take temperatures in the 20s Fahrenheit without being damaged, while many plants actually begin to show better foliage colors with cooler temperatures. These include ornamental kale and cabbage, Heuchera, and many ornamental grasses as well.
  3. Select plants that have a variety of tones that contrast and set off each other. Think about using colorful cultivars of Heuchera for their many foliage colors, and colorful grasses or grass-like plants, such as Pennisetum, Carex, Juncus, or the black foliage of Ophiopogon. See the list below of other fall plants to consider for your containers.
  4. Remember, a pot of mums looks fresh for three to four weeks at most, and then the show is over. Showy foliage from grasses or kale and cabbage will carry the display much longer.
  5. The fall foliage on evergreen succulents (Sempervivum ‘Hens and chicks’), and many of the stonecrop (Sedum) cultivars changes and develops more dramatic color once the temperatures stay cool.
  6. If you must have flower power, consider long- and late-blooming Salvia, Cuphea, or fall pansies or violas.
  7. When nighttime temperatures drop below freezing, have light blankets, large pots, or even an empty trash barrel handy to cover your container and protect the plantings from frost.
  8. As November passes, the time will come to disassemble your planter. Carefully place your hardy plants in a nursery bed or empty space in your vegetable garden plot to hold them over until next spring, when you can plant them in a permanent home to enjoy for another season.

I love my plant job

Salina Wunderle —  August 10, 2018 — 3 Comments

I recently was admiring one of the stately agaves at the Chicago Botanic Garden, and I had a genuine “I love my job” moment. This was not the first time and definitely will not be the last. I took a moment to reflect on that and why my job as a horticulturist is so much more than caring for plants.

Salina Wunderle 2I started off as a seasonal employee in the production greenhouses, where we grow and tend for the plants you see throughout the Garden. Now I’m one of five senior horticulturists. My crew—horticulturist Dino de Persio and technician Evan Hydzik—and I oversee the three glorious display Greenhouses, all interiorscapes, two beautiful bonsai courtyards, event plant displays, and beyond. I also work closely with our creative design team to produce our annual Wonderland Express and Orchid Show.

Some people ask me, “What is horticulture?” If you Google “horticulture,” this is what comes up: Horticulture (noun): the art or practice of garden cultivations and management.

In my position, I am blessed to work with plants from all around the world. If you use a little imagination, these plants can transport you to new and exotic places. Many of the plants in our collection can link you to other cultures through their traditional, medicinal, ecological, economical, and ethnobotanical uses. For example, not many people know the showy bougainvillea is a traditional medicinal and culinary plant of Mexico and Central America. We also have bizarre bat-pollinated plants, such as the breathtaking jade vine (Strongylodon macrobotrys) and many Cereus cacti. Some of my favorites are the cardamom spice (Elettaria cardamomum), breadfruit (Artocarpus altilis), cocoa (Theobroma cacao), and coffee (Coffea arabica)—all of which are all edible, of course.

Look at this plant I get to cultivate! This is the century plant (Agave americana).

Look at this plant I get to cultivate! This is the century plant (Agave americana). Our last century plant bloomed in 2010. When will this one grow through the greenhouse roof? You’ll just have to stay tuned to find out. Seriously, I love this job.

I get to share the stories of these plants with guests of all ages and walks of life. Connecting people with plants is certainly one of the great joys of my job. Recently, I became part of the advisory council of an initiative called Seed Your Future (seedyourfuture.org). This movement was founded in 2013 by Longwood Gardens and the American Society for Horticultural Science, and has grown to include more than 150 partners, including the Chicago Botanic Garden. The group’s mission is “to promote horticulture and inspire people to pursue careers working with plants.”

One way to do that is to introduce the world of horticulture to young people and show them the critical role plants have in all of our lives.

Earlier this year, Seed Your Future launched BLOOM, our first campaign to promote horticulture and inspire interest in careers in horticulture.

Our BLOOM microsite has fun games, videos, and more for young people to enjoy getting to know the world of plants. The amazing thing about Seed Your Future is that the website has an expanding bank of resources for parents, teachers, camp counselors, and mentors to use in their programs. All of this is free. I can say I would have loved a resource such as this along my plant journey, and I am honored to be a part of it now.

Working with Seed Your Future has helped bring my story full circle. It has shown that my job as a horticulturist allows me to do so many fulfilling things: play with plants of the world, share knowledge and stories with others, inspire kids and adults, work with brilliant people, and ultimately get challenged and grow.

Thank you for letting me share my “I love my job!” moments.

As plant collectors, we spend a lot of time and energy researching the flora of the areas we are going to visit. We search out areas of the world where the climate is similar to that of the midwestern United States, and we make lists. Lots of lists.

Massive spreadsheets document travel plans, emergency contacts; high-value germplasm that we hope to find at each of our planned collection locations; and costs: airfare, gasoline in the country, driver wages, botanist guides, food, and lodging. All of this data is condensed into a one-page document that our hosts submit to the national environmental agencies within each country for approval and permits for the trip. Among our goals on plant-collecting trips is to collect seeds to conserve and to look for plants of horticultural interest to display in our collections.

Paeonia tenuifolia

Invariably, some of the treasures we return with are unanticipated. Such was our discovery of a very large population of Paeonia tenuifolia that was unknown to Georgian scientists in the remote and sparsely populated Vashlovani Reserve—a peninsula-shaped area surrounded by Azerbaijan on three sides, containing large rolling hills breaking into badlands—areas so heavily eroded I thought I was in the Badlands of the Dakotas.

We were in search of seeds of unusual bulbs in the Vashlovani Nature Reserve with Peter Zale from Longwood Gardens (the trip organizer), Panyoti Kelaidis from the Denver Botanic Gardens, and Manana Khutsishvili from the Institute of Botany, Ilia State University.

It was one of those breathtakingly beautiful days, with the rolling grasslands backdropped by the snow-covered peaks of the Greater Caucasus Mountain Range. Dirt roads had not been graded in quite a while, and the sun-baked ruts left over from the winter rains gave rise to the trip joke: shaken, not stirred. This was definitely four-wheel-drive country.

One of our target species in this area was Merendera trigyna, a beautiful spring-flowering Colchicum relative with pale pink to white flowers about twice the size of Crocus and blooming about the same time. Our data source was a herbarium voucher on file with the Institute of Botany Herbarium in Tbilisi. Peter had entered the coordinates into the GPS receiver after lunch, and the road seemed to head in the correct direction. A couple of hours later we were on the border with Azerbaijan and the coordinates suggested we needed to cross the border—not a match with the written description of the location on the herbarium voucher.

We continued to skirt the border, and an hour later we found a hilltop that allowed Manana to make a cellphone call back to the herbarium in Tbilisi. Thirty minutes further down the track, on another exceptionally high hill, we learned the coordinate system recorded on the voucher was from a Russian GPS system, not the American system our GPS was programmed for.

By that time it was too late to retrace our steps. In new territory for all of us, we continued on the track paralleling the Azerbaijan border, knowing that eventually it would lead us to a small Georgian town. By this time, it was about 6 p.m., and as we surmounted another rise we were greeted with thousands of fernleaf peony (Paeonia tenuifolia) in full flower. Each flower was the size of a salad plate, and a deep, intense red. Unlike the 8-inch-high representatives of this species in our American collections, the whole population was 2.5 to 3 feet in height, with an equal width. This population was unknown to the Georgian scientific community until we managed to get lost and found it in the process of working our way back home.

A trip is planned for 2019 for the Republic of Georgia. It is timed to collect seeds from this population, as well as the nine other species of peonies native to this floristically rich country. Who knows what unsuspected treasures we will discover next year?

Summer is in the air. As the nights heat up, it’s a perfect time to get outdoors and entertain in your garden. Chicago Botanic Garden floriculturist Tim Pollak shares how you can bring the party to your garden with a few simple tricks for evening entertaining.

Plant light-colored flowers
Enhance the darkness of evenings by planting white or cream-colored foliage and flowers. White flowers and plants create brightness in your garden by reflecting moonlight, candlelight, and firelight. Some flowers even “glow” in the moonlight, including white and yellow lilies. Pollak recommends flowering shrubs such as hydrangea, roses, and hibiscus.

Add fragrant, evening-blooming flowers
In areas where you can sit and entertain, use plants that emit mood-setting fragrance. Scent in a garden carries farther and longer in the evenings than in daytime, said Pollak. Plus, evening blooming plants often give off strong fragrance that attracts night-flying pollinators (additional guests for your party). Some examples of especially fragrant plants include heliotropium, nicotiana, and ipomoea alba.

outdoor garden lightingInstall night accent lighting
Lure guests down the garden path with purposefully placed outdoor lighting. You can shine focal points on specimen plants, and create wonderful shadows and backlighting effects that will enhance the setting of your evening party.

Keep warm with fire pits
People are drawn to fire pits, which create a campfire-like atmosphere, said Pollak. Fire pits also serve as focal points in your garden, providing warmth, light, and a cooking source. Stay warm on cooler nights, and enjoy the light and ambience that make fire pits a natural gathering spot for entertaining. Many fire pit options are available, including natural or electric, modern or traditional, in-ground or portable. Be sure to consider the placement of seating as well, with flexible options in case of wind and smoke.

Enhance the mood with garden structures and sounds
Nighttime atmosphere can make for a magical evening. A few sensory features such as white or gray painted structures or statues, wind chimes or fountains will add the perfect finishing touched to your evening ambience.

Keep out pesky party crashers
Mosquitos are never a welcome guest at a nighttime gathering. Keep them at bay by eliminating all standing water. You can also use citronella (including the actual citronella plant, or candles, lamps, and tiki torches) to help keep them away.

Can’t make the wedding of Prince Harry and Meghan Markle? Visit the Helen and Richard Thomas English Walled Garden instead.

If you’re in Chicago this weekend, that means—like most of us—you didn’t get an invite to the wedding of Prince Harry and Meghan Markle, a graduate of Northwestern University. Get in the spirit of the occasion anyway by visiting the English Walled Garden at the Chicago Botanic Garden. This garden has enough connections to the British royal family to satisfy your royal appetite, and you won’t have to be up at 5 a.m. to start watching the wedding and feel part of the experience.

Here are just some of the connections to British royalty that can be found in the English Walled Garden:

The garden was dedicated by a member of the British Royal Family. The English Walled Garden was dedicated in 1991 by none other than Princess Margaret, Countess of Snowdon, who was Queen Elizabeth II’s younger sister. The occasion was fit for royalty, with a performance from a bagpiper, and an official dedication by the princess, who sported a lovely royal blue coat. You can find a plaque commemorating the dedication just outside the entrance to the garden.

Princess Margaret visits the opening of the English Walled Garden in 1991. Designed by John Brookes, the English Walled Garden contains six “rooms” that demonstrate traditional English gardening styles: Vista Garden, Cottage Garden, Pergola Garden, Daisy Garden, Courtyard Garden, and Checkerboard Garden.

A legendary designer created this garden. When the English Walled Garden was just an idea, the Woman’s Board of the Chicago Botanic Garden looked to legendary garden designer John Brookes for his vision. Known more for being a modernist, Brookes agreed to design our English Walled Garden in a more traditional style. In 2004, he was made a Member of the British Empire, an order of chivalry bestowed by the Queen for outstanding contributions to society. Brookes died in March 2018, but leaves behind a footprint that includes, along with the English Walled Garden here, many gardens on private estates and in town squares around the world. A quote from his last published book describes his legacy: “I have sired no heir, but I have given birth to perhaps a thousand gardens.”

The garden is divided into six “rooms,” and one was made as a nod to the working class. The least formal of the six different spaces in the English Walled Garden is the Cottage Garden room. It’s modeled after the type of garden a rural homeowner would create, and serves to be more functional than ornamental. You’ll see fruits, vegetables, and herbs growing together, filling every space possible. If you’re someone who’s not altogether fond of the concept of royalty, the Cottage Garden is a place to visit and ruminate on how the common folk get by.

Charles and Diana are there—but not together. The garden features two varieties of clematis with familiar royal names. Clematis ‘Prince Charles’ and Clematis ‘Princess Diana’ are both located in the same garden bed, but planted at opposite ends. You can find them next to the ramp exit leading to the adjacent Dwarf Conifer Garden.

The floral emblem of Scotland is there, but England’s is not. Planted as an annual this year along the west perennial border of the garden is Onopordum acanthium, more commonly known as Scotch thistle. The flower is so named because it’s similar to the thistle used as the national emblem of Scotland (which is technically Cirsium vulgare). If you’re looking for the national emblem of England, that would be the Tudor rose, a combination of the red and white roses of the Houses of Lancaster and York. But you’ll have to go outside the English Walled Garden to get a good view of roses. Peek through the terra-cotta tiles next to the Linden AllĂ©e or venture to the Krasberg Rose Garden next door. There’s a variety of rose named for Prince Harry’s grandmother and Meghan Markle’s future grandmother-in-law: Rosa ‘Queen Elizabeth’.

The Guardian has royal connections. If you enter the English Walled Garden from the main entrance on the west side, you can’t miss the Guardian. The sculpture was carved by Simon Verity, an English sculptor who has created pieces that stand in many English gardens, including one owned by Prince Harry’s father Prince Charles, the Prince of Wales, as well as Elton John (who is definitely music royalty). Constructed of semiprecious stones and minerals, the sculpture represents air, earth, fire and water, the ancient elements of earth.

Surround yourself in purple and feel like royalty. Now that spring has arrived (finally), there are plenty of blooms to be found in the traditional color of royalty. Blues and purples were a key part of Brookes’ design for the garden. You can find that color family prominently in the Pergola Garden room. Another can’t miss purple flower in the English Walled Garden is delphinium, a stately and regal bloom newly planted in two urns close to the Linden Allée.

Say hello to the lion. The lion has long been the symbol of England. The Barbary lion is the country’s national animal and also adorns a number of national symbols, from the coat of arms of the royal family to the England national football team’s logo. Naturally, there’s a lion in the English Walled Garden as well. Named Cuddly Lion, the sculpture was donated by Brookes and is located at the entrance.

Wander away from the English Walled Garden to find the plants and flowers of the royal wedding. While the English Walled Garden is full of botanical references and nods to English history and culture, you’ll have to trek to the Regenstein Fruit & Vegetable Garden to find plants and flowers that are part of Prince Harry and Meghan’s wedding celebration. Traditionally, lemon myrtle from Queen Victoria’s holiday home on the Isle of Wight has been featured in the bride’s bouquet of royal weddings since Victoria’s daughter (also named Victoria) was married in 1858. The flowering plant is expected to make an appearance in Meghan’s bouquet. There’s lemon myrtle located inside the greenhouse, at the center of the garden. One tradition Prince Harry and Meghan are not following is with their choice of cake. Instead of the traditional fruit cake, their wedding will instead have a cake made of lemon and elderflower. Cross the bridge to the Fruit & Vegetable Garden and veer left. You’ll find several elder trees (Sambucus nigra) along the shoreline. Looking for a reason to head back to the English Walled Garden? Finish up your homage trip in honor of the royal wedding by seeking out lemon thyme, planted in several different spots in the English Walled Garden. Take a sniff and, with the right bit of imagination, it’ll be like you’re in London with the royals after all.
