Peace & Tranquility in Washington D. C.

U.S. National Arboretum

U.S. National Botanic Garden

Lost in the nonstop news coming out of Washington D.C. today is news of the remarkable treasures of our U.S. National Arboretum & Botanic Garden, “Where Science meets Beauty”.

466 Acres of Green

Since 1927 the National Arboretum’s mission “to combine science and beauty for the study of flowers, shrubs, and trees” has thrived, thanks to the Department of Agriculture.  Located away from the National Mall in NE Washington, DC, is 446 acres of a green oasis in a densely populated area of the country. A visit here removes you from the politics and the traffic of the area. There are formal gardens, herbariums, bonsai, and grand trees.

There is so much to explore, if you hope to see it all you need a map and a plan to cover the nearly 10 miles of roadway. Visitors can travel by car, or bike. The arboretum works to make “scientific discoveries contributing to sustainability of landscapes”.  The research is part of the nationwide network of Extension Services (including the University of AZ) as well as international cooperation. Here is where the work of the USDA Plant Hardiness Zone Map is done. The interactive map lets me put in my home garden zip code. The mission statement reminds me that American the Beautiful is in reference to our vast and varied landscape.

Wisteria Walkway US Botanic Garden

Spring is an especially beautiful time in the Arboretum as 10,000 Azaleas and 1000 Camellias, which have been hybridized to withstand the colder temperatures of the D.C area, burst into bloom along with daffodils, crocuses, magnolias, and other seasonal flowers.


A pair of Bald Eagles, ‘Mr. President’ and ‘The First Lady’ has been adding to the excitement of the season for the past four years nesting in the top of a Tulip Poplar tree and raising their chicks. A live streaming Eagle Cam allows for observation (   during the nesting. There are also viewing scopes on site to observe the nest.

Japanese Maple

Considered to be one of the finest collections in the world, is the small forest of dwarf confiners and Japanese Maple trees, a gift of William Gotelli.  In 1962 Gotelli donated 800 dwarf conifers to the arboretum from his New Jersey garden. These dwarf evergreens sweep, droop, and twist in delightful shapes. There is a National Grove of State trees and flowers bringing together the flora and fauna of the country.

The 2.5-acre National Herb Garden celebrates the role of plants in the history of our nation.  Here I learned about strewing herbs, such as rosemary, sweet rushes, and pine bugs laid on the bare floors which would release their scent when walked upon, perfuming and disinfecting the air, a desired effect long before aerosol air fresheners of today.  In the Medicinal garden, I discovered Southernwood, (Artemisia abrotanum) was hung in courtrooms as a way to stop the spread of disease and keep bad odors away.  The continuing influence of Greek Physician, Dioscorides and his treatise from 60 A.D are acknowledged with a selection of plants, such as Rose Campion, (Lychnis cornonaria) which he prescribed the seeds to be drunk with wine to help those bitten by scorpion. (In 2012 an AZ woman was billed $83K for the antivenin which seems quite a contrast by comparison.)

Coffee Beans

A Beverage Garden highlights plants used for herbal teas, liquor, and coffee. A sweet scent filled the air in the Fragrance Garden which displays plants used for aroma and perfumes, and an Industrial Garden features plants that supply sources of fuel, fiber, and other essential products to keep the world running.

Japanese White Pine, bonsai since 1625

In 1976, as part of the celebration of the nation’s bicentennial, the National Bonsai & Penjing Museum was established.  Bonsai is the Japanese art of miniature trees and Penjing is the Chinese form.  Today there are 150 miniature trees in this collection including the work of North American Masters.  The oldest tree (in training as a bonsai since 1625) is a Japanese White Pine, a gift of Masaru Yamaki. This tree survived the August 5, 1945, atomic blast in Hiroshima.    This precious tree, given 30 years later to the U.S. as part of a gift of friendship from the people of Japan represents the healing power of nature between two countries once devastated by war. This is where my plan to explore the entire Arboretum fell apart as this collection of grand horticultural art fascinated me.

22 Corinthian Capitol columns

The most thrilling site of the arboretum is the 22 Corinthian Capitol columns sited on a knoll of the Ellipse Meadow.  The columns were constructed in the early 1800’s from Virginia sandstone to hold the Capitol Building dome. Undersized from the beginning, the columns were replaced in 1958. But it was not until 1980 that the idea for their relocation to the Arboretum took shape. It is quite a story of how they ended up here. The impact of these columns standing tall, complete with a reflecting pool, is beautiful and thought-provoking.

Capitol Column Detail

The Greeks influenced the Romans and the Romans influenced the western world in language, politics, philosophy, education, and architecture. Corinthian columns, a symbol of classical Greek architecture, from the country where the ideas of democracy began, stand peacefully while the tumult of a living democracy continues.

US Botanic Garden Entrance

A separate but no less significant place for a gardener’s attention is the U.S. Botanic Garden located on the National Mall. It was established by Congress in 1820 during the height of international excitement of plant exploration and discovery and continues operation today as part of the Library of Congress. Purposed to be “a botanic garden to collect, grow and distribute plants of this and other countries that might contribute to the welfare of the American people,” this small garden represents the historic collection of 1000’s of plant specimens dating as far back as 1842 gathered by Columbia Institute for the Promotion of Arts and Sciences the first plant exploration effort by our fledgling nation. Today any plants confiscated at the U.S. borders as a violation of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) comes here to be rescued.

Lord & Burnham 1933 Conservatory

Escaping a rainy day, I ducked inside to explore the historic Lord & Burnham 1933 Conservatory, the architectural centerpiece of the garden. Two courtyard gardens, display halls, and 10 garden rooms safe inside under glass attempt to represent our national landscape.

America the Beautiful is dependent on plants, trees, bees, and other pollinators living in an environment of fertile soil, predictable climate, and reliable source of clean water.  In Washington D.C. there are government workers striving to achieve this, and their story needs to be told and supported if we want to continue to sing:

O beautiful for spacious skies

For amber waves of grain

For purple mountain majesties

Above the fruited plain!
