Flanders Field Poppies at the National Museum of American History

The poppy became an international symbol of remembrance of World War I through the efforts of an American professor from Georgia, Moina Michael. While working at the 25th Conference of the Overseas YMCA War Secretaries in New York City Michael heard a reading of the poem “In Flanders Fields” by Lt. Colonel John McCrae, MD (1872-1918) of the Canadian Expeditionary Force.

Michael was so moved by the poem that she resolved to wear a poppy in remembrance of the war and bought them for attendees of the conference on November 9, 1918. Two days later, on the 11th hour of the 11th day of the 11th month of 1918, Germany signed an armistice agreement with the Allies thus ending the war. Michael carried on work to make the poppy a symbol for honoring the war dead as well as a way to raise funds for veterans, a symbol that endures today.

To commemorate the 100th anniversary of the World War I, Smithsonian Gardens planted corn poppies (Papaver rhoeas) outside the National Museum of American History. The seeds sown were, in part, collected from the Flanders Fields of Belgium.

In Flanders Fields
by John McCrae, 1872 – 1918

In Flanders fields the poppies blow
Between the crosses, row on row, 
That mark our place, and in the sky, 
The larks, still bravely singing, fly, 
Scarce heard amid the guns below.

We are the dead; short days ago
We lived, felt dawn, saw sunset glow, 
Loved and were loved, and now we lie
In Flanders fields.

Take up our quarrel with the foe! 
To you from failing hands we throw
The torch; be yours to hold it high! 
If ye break faith with us who die
We shall not sleep, though poppies grow
In Flanders fields.

DIY: Hanging Baskets

The Smithsonian Gardens greenhouse production team creates 200 hanging baskets for display throughout our gardens each year. Baskets are produced in three sets and changed out each spring, summer, and fall season.

Production team members Joe and Jill were kind enough to share a behind-the-scenes look at how they create these popular hanging additions to our gardens.

This year Jill and Joe useed a combination of Calibrachoa Minifamous ‘Double Deep Yellow’, Lobelia erinus Laguna ‘Sky Blue’, and Sutera cordata Snowstorm ‘Giant Snowflake’  in our spring baskets. The result? An EXPLOSION of yellow, blue, and white! You can see these spectacular baskets now out in our Enid A. Haupt Garden and Kathrine Dunlin Folger Rose Garden.

Here’s a step-by-step guide showing how our pros create the baskets for our gardens. DIYers, we’re looking forward to seeing pictures of what you create!

Behind the Orchids: Changeouts in the Kogod Courtyard

This week I took a break from work on the Orchids: Interlocking Science and Beauty exhibition to help Smithsonian Gardens’ horticulturists with planters in the Robert and Arlene Kogod Courtyard at the Donald W. Reynolds Center for American Art and Portraiture.  The Reynolds Center, which houses the Smithsonian’s National Portrait Gallery and Smithsonian American Art Museum, underwent a major renovation in the early 2000s to enclose its central courtyard, creating a beautifully maintained interior space filled with natural light. If you are a fan of architecture or just like cafes in nice spaces, you should definitely go check it out! Smithsonian Gardens’ horticulturists care for eight large planters throughout the courtyard and I’ve made two trips over the past couple weeks to help replace plants in two of the eight planters. With each planter over 300 square feet, it’s quite the production.

In fact, on Kogod changeout days, help is needed from several members of the Smithsonian Gardens staff. This week, I joined a team of five staff members and one volunteer to tackle the job. Changeouts occur regularly. Often new plants are rotated onto display for seasonal purposes or to freshen up the courtyard for the many thousands of visitors that regularly pass through. Earlier this year, the courtyard display featured Cymbidium orchids and their endless blooms gave spectacular color to the space.

Kogod changeouts not only address aesthetic purposes. Changeouts are also useful for ensuring and maintaining plant health. Sometimes a new plant may not do so well in the space. There might be a pest problem that requires removing a plant or a plant may simply need to come out because its life cycle is ending. Whatever the reason, making the effort to assess each plant’s health ensures a beautiful display.

During the first step of a planter changeout, all the plants (except for the trees) come out of the planter and are placed onto tarps laid out on the ground. Plants are assessed to determine whether they are still in good condition for display, if they need attention, or if they should simply be composted. Once the current plants are sorted, new soil is poured into the bed to level the surface with the edge of the planter. Once again, adding soil serves both an aesthetic and functional purpose. Fresh soil both looks better and allows the new plants going into the planter to have an easier time rooting. This is one of the most labor-intensive parts of the process as each of the planters easily takes in 80 50-pound bags of new soil.

Once the soil is in, additional nutrients are added and mixed in evenly before introducing the plants. The Smithsonian Gardens’ interior plantscape designer and crew then work to create a planter design with the plants available instead of trying to fit the plants into a predesigned plan. I feel this allows the planters to come out looking their best and showcases plants that we may have been able to save from the previous design that we did not expect to have. After helping with two changeouts, it’s really a nice surprise to see how it all comes together each time.

The next time you are visiting the Smithsonian American Art Museum or National Portrait Gallery,  make sure to swing by the Kogod Courtyard and enjoy the wonderful green inside, no matter what the weather may be like outside!

Cultivate ’14: Plants and Art

I had the opportunity to travel to Columbus, Ohio, last July to attend Cultivate ’14.  This annual conference is held for people from all aspects of the horticulture industry, including growers, retailers, landscapers, interior plantscapers, floral designers, and educators. With educational sessions, the largest horticultural trade show in North America, wonderful tours to attend, and over 10,000 attendees, there was so much to see and learn while I was there.

As part of the conference, I was fortunate to be able to visit the Franklin Park Conservatory and Botanical Gardens in Columbus.  I have always been fond of conservatories and greenhouses, and this one did not disappoint!  The conservatory itself, comprised of 8,300 sq. ft. of glass roof space, first opened its doors to the public in 1895 to show off its collection of palms.

One aspect that really drew me in to all of the beautiful plant displays there were the Dale Chihuly glass pieces that were exhibited throughout the conservatory.  I learned that Chihuly’s artwork was first displayed in the conservatory in 2003.  Because of a marked increase in attendance, the Friends of the Conservatory decided to purchase many of those glass pieces so that they could be shown permanently.  There is something about the way the beautiful glass, with its electric colors, reflects the sun in such a gorgeous setting.  It warms me from the inside out.

That really got me thinking about how important art is in the garden: bringing these two elements together to draw in people to see the gardens.  It is a way for gardeners and plant lovers to come to such a lovely, natural setting to appreciate art.  It is equally as valuable to bring lovers of art into a garden setting, which is beautiful and imperfect—quite a different setting to display artwork than the stark white walls that we often see in a gallery—and enable them to appreciate the artwork in a more natural setting.  The synergy created by placing these two components of artwork and gardens in the same space makes the combination of the two work that much more effectively together than they would on their own.

We at Smithsonian Gardens are so fortunate to have such a beautiful backdrop in which to display our plants.  The museums themselves are works of art, inside and out.  We have entire gardens that are dedicated to displaying artwork (such as the Hirshhorn’s Sculpture Garden), and others that are gardens, first and foremost, that also display artwork (the Haupt Garden, American Indian Museum, and Natural History Museum, to name a few).

I work primarily with plants used in interior spaces, and while I can’t necessarily work with “gardens” and artwork, the plants I grow and care for in the Smithsonian greenhouses are used inside the museums where even more pieces of art are displayed.  The trip to Franklin Park Conservatory has inspired me to think more creatively about the plants I grow, and to consider new ways in which the plants can be arranged to complement the artwork they will be placed around, or even the space in which the plants will be displayed.

The next time you visit a space that displays horticulture and art, take the time to appreciate how much more you get out of your experience by having both plants and artwork working together.

What Happens When a Bunch of Horticulturists Get Together?

They all go to Cultivate ’14 in Columbus, Ohio in July.

I had the wonderful experience of attending Cultivate ’14 in Columbus, Ohio July 12 – 15, 2014. Formally known as the Ohio Short Course, the symposium is one of the largest events in North America. The show is attended by over 9,000 garden retailers, greenhouse growers, landscapers, interior designers, educators, researchers, and many other professionals involved in the green industry.

Top notch educators and speakers are invited to speak on over 140 topics about pest control, new plant varieties, growing techniques, interior design, and green walls. Attendees have the flexibility to attend as many of the seminars as they can. Attending these seminars is a great way to get new ideas on growing techniques, identifying common diseases and insects that may attack greenhouse crops, and even proper techniques on using yellow, sticky insect trap cards.

The trade show is the one of the largest around. I was able to walk around at my leisure and see all of the new and innovative products that are available or will be made available to our industry in the future. The trade show is also a great time to network with sales representatives that I talk to sometimes on a weekly basis. I also establish new relationships with salespeople trying to sell the newest and brightest products in the industry. Personally, the trade show is a wonderful opportunity to “hook up” with former coworkers and sales representatives I have known for over twenty years.

One of the highlights of the show is getting to see many of the new plant varieties and introductions. There are hundreds of new and exciting plants and colors at the show. Aisle after aisle of annuals and perennials line the lobby at the convention center. Many of these new varieties can be seen in the fabulous displays all throughout the show.   I gain a ton inspiration when looking at the wonderful new selections and then enjoy bringing all of my inspiration back to share with my coworkers at Smithsonian Gardens.

Another wonderful highlight of the trip is the bus tour to greenhouse operations in the Ohio area. I was able to tour two family owned production/retail facilities. Going on the tours allows me to see what other growers are doing and taking a peek at their innovative ways of producing large quantities of high quality plant material to be sold to retail garden centers.  The bus trips also establish relationships with other people in the industry. Conversations are started and soon everyone on the bus seems to know one another. Information and ideas are exchanged while spending most of the day on the bus. These people on the bus come from all over the country. My bus had people that came all the way from Canada and Hawaii!

The really fun part of the trip to Cultivate ’14 was the visit to the Franklin Park Conservatory a couple of miles outside the city limits. Their display of Chihuly glass (more than 3,000 pieces in the permanent collection) was awesome! The plants displays were amazing as well. Highlights of the conservatory included a palm house, a rain forest, a butterfly house, lots of amazing bonsai, and a gift shop and café.

Attending Cultivate is always a wonderful experience. The event is truly a great opportunity to become motivated and inspired by all of the beauty and knowledge the show brings to the green industry and to me.

Update on the Eastern Bluebird Trail

Eastern bluebird nesting boxes

In 2012, the Smithsonian Gardens Green Team developed an Eastern Bluebird Trail at our greenhouse complex in Suitland, Maryland. The trail of ten paired nest boxes was designed to support and expand the year-round resident Eastern Bluebird population. By the end of the 2013 nest season, the bluebird population had expanded to about thirty birds.

What happened in 2014? We began monitoring the trail in March, looking for the first signs of nesting behavior. The monitoring continued through July and in that time, no Eastern Bluebirds have been seen at or around the greenhouse complex. We believe the resident population migrated to another location due to a harsh winter of repeated deep Arctic cold blasts starting in late November and persisting through March. In addition to the cold, we believe the bluebirds did not have enough food to support their population.

American beautyberry (Callicarpa americana, top) and flowering dogwood (Cornus florida, bottom) are bluebird favorites!

Bluebirds rely on fruit for more than thirty percent of their diet. In the winter, when insects are scarce, they depend on persistent fruits more than at any other time of year. The SG Green Team is committed to planting more native tree and shrub species around the facility to provide a sustainable winter habitat for the birds. Planting trees and shrubs not only provides food for birds but also provides shelter from harsh winds and cold temperatures.

Way Down Yonder in the Paw-Paw Patch

Pawpaw tree blossoms

Ever heard of the pawpaw tree?  Ever tasted its fruit?  Did you even know it had fruit?  Though it may not have the name recognition of an apple or a peach tree, pawpaw trees have a long and important history in the United States. In 1541, Hernando de Soto observed Mississippi Valley Native Americans growing pawpaws and eating the fruit. According to scientist Neal Peterson, the Spanish mistakenly named the pawpaw fruit “papaya.” Spanish explorers selected this name because they observed pawpaw fruit to have a similar green skin and orange flesh to a papaya. Overtime, the English language transformed the fruit and tree species name from papaya to pawpaw (Asimina triloba).

According to James A. Little in his 1905 A Treatise on the Pawpaw, pawpaw fruit helped sustain Native Americans and early American settlers in times of harvest failure. Little wrote that pawpaw trees needed little maintenance in order to survive in the wild, unlike apple, pear, or peach trees. Thanks to its resilience, Native Americans and early pioneers enjoyed pawpaw fruit as a dependable source of fiber and nourishment.  Even members of the Lewis and Clarke Expedition survived on pawpaw fruit during their long journey west in 1804-1806.

Found between Georgia  and Northern Michigan, pawpaws extend across eastern portions of the United States. Unlike the tropical members of the Annonaceae family to which it belongs, pawpaw trees thrive in harsh conditions of snow and ice. Despite this resilience, pawpaws still struggle to reproduce. Scientists believe the tree is ineffective at attracting flies and beetles to pollinate its flowers, thus creating challenges for reproduction.
The pawpaw tree produces a very nutritious and delicious fruit, which is actually a berry.  The pawpaw berry is also called a “custard apple” and is said to taste like a mix between a banana and a pear, with a hint of vanilla.  The name custard apple derives from the creamy texture of the fruit.

Pawpaw tree foliage

The pawpaw tree has striking foliage in autumn. Pictured here on the grounds of the National Museum of Natural History.

Smithsonian Gardens currently has seventeen pawpaw trees in its Tree Collection.  They can be found in the Native Landscape garden at the National Museum of the American Indian, the Butterfly Habitat Garden adjacent to the National Museum of Natural History, and the National Air and Space Museum.

Next time you stop by one of the Smithsonian gardens keep an eye out for this beautiful tree with a deliciously-interesting past.
