One of the best things about working for a botanical garden like Smithsonian Gardens is that part of our mission is to produce splendiferous specimen plants. What makes it even better is that we often get to exhibit these specimens at the peak of their glory!
Alex and Melanie of our interiorscaping staff make sure that many of these extraordinary orchids are on display for the public to see in Smithsonian Gardens’ three display cases at the Smithsonian’s National Museum of American History (NMAH). This week is no exception. A superbly bloomed Cattleya alliance hybrid, Brassocatanthe Julie Morrison (Brassanthe Maikai X Brassocattleya Morning Glory), is almost bursting out of one of the cases!
This hybrid is a combination of three species from three different genera; the hearty, purple Guarianthe bowringiana which contributes a large flower count and lovely amethyst color; the Cattleya purpurata from Brazil which contributes a large flower size and tremendous vigor to the hybrid; and the fragrant, white Brassavola nodosa.
Brassavola nodosa may be the least colorful of the hybrid’s three parents, but it displays a tremendous variability. Small, barely-discernable spots deep in this orchid’s lip turn into brilliant, spotted patterns when it is used to create a hybrid with a more colorful species, as in the case of this Brassocatanthe. The flower form of the Brassavola also dominates in this type of breeding. No matter what it is crossed with, the resulting hybrids almost always have narrow segments, spots, and a flaring lip.
Brassavola hybrids are always vigorous and charming with wonderful color and are therefore highly recommended for use in tropical gardens and in home orchid growing. Smithsonian Gardens has several clones of Brassavola hybrids and their species parents in its orchid collection; many of them are displayed at NMAH as they bloom. You can also see these and other beauties from the Smithsonian Gardens Orchid Collection starting February 27, 2016 at this year’s Orchids in Focus exhibition hosted in partnership with the United States Botanic Garden. Stop by and see these glorious orchids if you’re in Washington, D.C.!

Note: the January 23rd program at Purcellville Library has been canceled due to inclement weather. See you on February 6th!
As you kick back with your seed catalogs and a mug of hot tea this winter, dreaming of summer blooms and bounty, take a moment to think about the important role gardens play in our lives. Gardens are a place to relax, enjoy nature, exercise, express our artistic sides, and spend time with family and friends. Whether it’s roses, heirloom string beans, or perennials you’re growing, gardens tell us something about ourselves and our personal history. If you’re itching to get outside but the ground is frozen solid, consider taking a moment during the down season to share your garden story with our digital archive, Community of Gardens. It could be an interview with a neighbor who gardens, the memory of your grandfather’s peonies, the history behind the apples grown on a family orchard, or the retreat in your own backyard.
Local gardeners, join us in preserving our garden history for future generations! Smithsonian Gardens and the Purcellville Library are teaming up for the first-ever Community of Gardens story drive. Join us for two events at the Purcellville Library this winter:
Community of Gardens: History in our Gardens
- Saturday, January 23, 2 p.m. Cynthia Brown, Smithsonian Gardens education manager, will give an overview of the Community of Gardens program and how gardeners can help the Smithsonian preserve everyday garden history at this kick-off event.
Community of Gardens: Harvest
- Saturday, February 6, 2 p.m. Bring your photos and memories of gardens, family farms, and orchards. In collaboration with the library we will be scanning photos and saving stories to capture personal stories of gardens and their importance in American life.
Both of these free events take place at the Purcellville Library: 220 East Main Street, Purcellville, Virginia, 20132.
Not able to make it? You can participate by submitting your garden story (or your neighbor’s, your mother’s, or your grandfather’s) online at communityofgardens.si.edu.
We are a nation of gardeners. Thomas Jefferson grew over 300 varieties of plants at his Monticello home and like any dedicated gardener kept meticulous records detailing the triumphs (and failures) of his adventures in gardening. In the nineteenth century Italian immigrants introduced new vegetables like artichokes to the United States. Today, heirloom seeds originating from around the globe—or grandma’s backyard—can be purchased online and grown wherever we make a home. The Smithsonian Gardens Victory Garden at the National Museum of American History tells a story of citizens feeding their communities during wartime years, as well as a story of the diverse cultures that comprise the American people. In the summer ‘Carolina Gold’ rice, a traditional crop from the Carolina Lowcountry, can be found growing only a few feet from ‘Corbaci’ sweet peppers, a hard-to-find heirloom from Turkey.
April is National Garden Month, and we are celebrating the diversity of American gardens and the gardeners who make them grow. Small gardens and large gardens, community gardens and backyards, our diverse stories are part of a verdant quilt of gardens growing across the country. Gardens tell us where we’ve been, and where we are going. They can tell us stories about how people in our communities lived in the past and articulate our cultural values in the present. So often our everyday stories—the dahlias bred by a great-uncle, the nursery owned by a family for generations, the hot peppers grown as a reminder of a faraway island childhood—are lost to the historical record, and therefore lost to future generations.
Community of Gardens is our answer to the call to preserve our vernacular garden heritage. Community of Gardens is a digital archive hosted by Smithsonian Gardens, in partnership with our Archives of American Gardens, and created by YOU. It is a participatory archive that enriches and adds diversity to the history of gardening in the United States and encourages engagement with gardens on a local, community level. The website uses a multimedia platform that supports images, text, audio, and video. Visitors can add their own story to the digital archive, or explore personal stories of gardens from around the country.
To contribute a story to the digital archive visit the “Share a Story” page on the Community of Gardens website to sign up for an account. Once you have set up your account you may then add a written story and photographs. If you’d like to add video or audio files to your story email them to firstname.lastname@example.org. You will hear from a Smithsonian Gardens education staff member within a few days, and your story will be posted on the website usually within 3-5 business days. Once you have shared a story, share another story, or encourage your friends and neighbors to do the same!
We are looking for any story about gardens and gardening in America—even stories of Americans gardening abroad. Here is just a sampling of the stories we are looking to include in Community of Gardens:
- What’s growing in your own backyard, or on your apartment balcony? What motivates you to garden and how did you get your start? How does gardening enrich your everyday life?
- Interview a neighbor or family member about their garden.
- Memories of gardens past. Do you have strong memories of your grandparents’ garden, or visiting a public garden that no longer exists? Gardens can live on in stories and images through the archive.
- Family history. This is a good opportunity to get out the photo albums and scan old family photographs. Are you a fourth-generation gardener like Paul, pictured above?
- Community gardens—past and present.
- Did you immigrate to the United States from another country? How do your traditions and culture play a role in your garden?
- College and university gardens.
- School gardens. Involve your students in telling the story of their garden!
- Pollinator gardens and beekeeping.
- Americans gardening abroad. Are you a veteran or member of the Foreign Service? Did you keep a garden while living abroad? How did living in another country influence your garden?
- Sustainability and eco-friendly gardening.
- Stories of gardens committed to providing food access in urban areas.
Join us in preserving our national garden heritage—this month and every month. What is your garden story?

The Smithsonian Gardens Tree Collection currently consists of over 1,850 trees, approximately 1,400 of which are located on the downtown Washington, D.C. and Anacostia campuses. These trees add beauty to our grounds, and they offer myriad environmental and health-related benefits. Unfortunately, it seems that trees are constantly under attack by a host of problems, ranging from severe climate, to native and exotic pests and diseases, to damage from construction and development projects, to the tough urban environment in which they grow. Once these plants become stressed, it’s more likely that they will suffer due to one or more of these issues. In addition, as trees grow, certain structural defects can develop which may cause problems in the future, especially when severe weather events can exploit the inherent weaknesses in these defects.
For these reasons, we at Smithsonian Gardens take a proactive, rather than reactive, approach to caring for these green assets. Oftentimes, defects, cultural stressors, or insect and disease infestations that have gone unnoticed for a time can be difficult, if not impossible, to reverse. Therefore, a thorough health and structure assessment of these trees was completed at the end of 2014. This assessment consisted of a top-to-bottom, 360 degree visual evaluation of each tree. All defects and other potential issues were noted and assigned a rating based on the severity of the condition observed.
What we had at the end of the evaluations was a complete list of trees, their problems (if they had any), and recommendations for correcting anything of concern. Based on the ranking system, we now have an organized and detailed list of what maintenance and tree care work is needed, with a clear indication of where we need to start. This has enabled Smithsonian Gardens to find and fix issues before they become more serious, and gives us the ability to be proactive with our tree management. It also gives us a better idea of how to budget for upcoming maintenance needs. Prevention is the best medicine, and any time we can find and correct an issue before it becomes serious it allows us to keep our trees happy and healthy for many years to come.

As we gaze around at the beautiful autumn colors that our trees are showing us, we’re trying not to think about the arrival of the cold and snowy weather of winter. However, arrive it will, and now is the time to prepare your trees for those coming winter months. Although all trees are potentially susceptible to winter injury, young and/or thin-barked, and broadleaf evergreen trees require the most preparation.
Excessively cold temperatures, wind, and quick temperature changes can cause drying, browning, and death of evergreen foliage. This problem is most prevalent on broadleaf evergreens such as rhododendrons, laurels, boxwoods, and hollies. To help prevent this damage, construct a barrier of heavy burlap, like a fence, to block drying winds from their prevailing direction. If the entirety of the plant is exposed, loosely wrap it in burlap. In either case, be sure to leave the top of the plant exposed so light and air penetration can still occur. In addition, it is important to keep watering your trees up until the time of the first hard frost. A 4-6 inch layer of mulch over the root zone will also help the soil retain warmth and moisture. (Remember not to pile the mulch up against the trunk of the tree.)
Another issue of concern, which is also caused by rapidly fluctuating temperatures, is sunscald. This occurs when the sun has warmed the trunk of the tree, and then that trunk is rapidly cooled upon sudden shading from a cloud, etc. This condition results in elongated, dried and cracked areas of dead bark. This can be prevented by wrapping the trunk with commercial tree wrap (available at most home and garden centers) or other light-colored material. This will reflect sunlight and keep the bark at a more consistent temperature. The wrap should be placed on the tree in the fall and removed in the spring, after the last frost.
Broadleaf evergreen foliage damage and frost cracks are influenced by many factors, including plant species, location, drainage, natural protection, and how well established a plant is in the landscape. There is no specific temperature at which damage occurs, but if the forecast calls for temperatures below the average seasonal low (29-33°F for Washington, D.C.), it is best to utilize the protection methods outlined above.
Tree branches can be prone to breakage from heaving snow and ice loads and by strong winds. Weakly attached, overextended and broken limbs should be pruned. Trees with an upright form, such as juniper, arborvitae, and clump birch, can be wrapped in burlap, or held together by wrapping the branches collectively with twine or rope. Any wrapping material should be removed in the spring.
When natural food sources grow scarce in the winter, rodents may feed on the young bark and cambial tissue of trees. Plastic tree guards or a cylinder of ¼” wire mesh placed around the trunks of young trees will help prevent this damage. Be sure to remove these guards once the spring has come so the tree does not wind up growing into them.
Trees possess an extraordinary ability to withstand severe winter weather, with some being more hearty than others. However, with proper care and attention, your trees should come through the winter ready to show off their new flowers and foliage for spring.

BOO! In honor of Halloween, we are celebrating another #SpookyPlantsWeek. Here’s our round-up of the weird, creepy, gross, scary, and wonderful plants that we featured on Facebook this week. All can be found growing in our gardens at the Smithsonian museums or in our greenhouses in Maryland.
In January 2015, Smithsonian Gardens, the U.S. Botanical Garden, and the National Museum of Natural History will open a new temporary exhibit, Orchids: Interlocking Science and Beauty. This three-month exhibition (January 24-April 26, 2015) will feature thousands of live orchids and offer visitors the opportunity to explore how new ideas, technologies, and inventions change the way we study, protect, and enjoy these beautiful plants.
Volunteer orchid interpreters will have the opportunity to engage the public in this beautiful exhibition space and help visitors understand how each new innovation, like a puzzle piece, fills in gaps in our knowledge and creates a larger and more complex picture of orchids. As a volunteer, you will be trained to answer questions, provide additional information, and offer visitors short, hands-on activities to encourage them to think more deeply about how we study, protect, and enjoy orchids. You will also have the opportunity to assist with public programs and special events related to the exhibition.
Volunteer Position Duration: November 17, 2014 – April 26, 2015 (including training)
Training: Four training sessions beginning in November. Training sessions will include sessions on museum learning, visitor engagement, and exhibit content. Each session will be led by Smithsonian Gardens’ museum educators and orchid experts.
Qualifications: Volunteers should have an interest in orchids (though prior knowledge is not necessary) and in be comfortable working with diverse audiences. Good communication skills are a must. Experience teaching or delivering interpretive tours/programs is a bonus.
APPLICATION DEADLINE – OCTOBER 30, 2014
