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.

Smithsonian Gardens manages the health and maintenance of 1,873 trees in the Washington, D.C. area. As you walk around the Smithsonian gardens and museums you may notice a common theme: many of these trees are mature specimens with historical context and connection to the museums they surround. This is extremely evident as you walk the grounds of the National Museum of Natural History, where the extensive American elm plantings bring us back to a time when Ulmus americana was the predominant street tree in America. In fact, the large specimen on the corner of 9th Street and Constitution Avenue predates the museum, which celebrated its centennial in 2010.
As Dutch Elm Disease (DED) has wiped out the majority of stately American elms throughout the U.S., we at Smithsonian Gardens work diligently to monitor and manage our trees in order to prevent the spread of this lethal disease.
It is with this management strategy in mind that we carefully select replacements when elm trees at the Smithsonian need to be removed. When one of the younger elms on the north lawn of the National Museum of Natural History was critically damaged during a storm, we once again debated and discussed which “resistant” elm to replace it with. One of the best choices for a true Ulmus americana replacement is the ‘Jefferson’ Elm (Ulmus americana ‘Jefferson’), selected through the collaborative efforts of the National Park Service and the USDA’s Agricultural Research Service (ARS).
This tree was selected for its excellent DED resistance and the fact that as a true species, it exhibits the classic American elm form, unlike some of the resistant hybrids.
‘Jefferson’ elms leaf out earlier in the spring and maintain their green color better in the summer than other U. americana specimens. We were very lucky to receive this tree from the National Park Service as it is just becoming available in the commercial trade at this time, and can be difficult to find. The National Park Service propagates ‘Jefferson’ by cuttings from the original tree, located on the National Mall, and grows the seedlings for six years at its National Capital Region Nursery. It is a long process and a difficult one, as only about 5% of the cuttings live to become mature trees. Hopefully this selection will become more common in the nursery trade so that we can once again plant these majestic trees with confidence. Until that time, we are very thankful for the ongoing collaboration between the National Park Service and Smithsonian Gardens to ensure that the American elm still graces the Washington, D.C. landscape.
