Celebrating Trees: Inspiring Arbor Day Stories

It’s Arbor Day! That means it’s time to celebrate all of the wonderful benefits that we get from trees, and to plant trees to increase those benefits. Newspaper editor J. Sterling Morton is usually credited with first proposing the tree-planting holiday called “Arbor Day” in Nebraska in 1872. While Morton’s Arbor Day was a first in the United States, the celebration of a day devoted to trees actually has roots hundreds of years earlier.

The first documented celebration of an Arbor Day was organized by the mayor in the Spanish village of Mondoñedo in 1594. Today, a small marker commemorating this event can still be found in the town (now known as Alameda de los Remedios). The first “modern day” Arbor Day happened in Spain in 1805 in the village of Villanueva de la Sierra and was organized by a local priest, Don Ramón Vacas Roxo. According to author and professor Miguel Herrero Uceda, Don Ramón was “convinced of the importance of trees for health, hygiene, decoration, nature, environment and customs” and decided “to plant trees and give a festive air.” After celebrating Mass on Carnival Tuesday, Roxo, accompanied by other clergy, teachers, and villagers, planted a poplar tree. The celebration and plantings lasted three days. The priest was so moved by the importance of trees that he wrote a manifesto in their defense and sent it to neighboring towns to encourage people to protect nature and establish tree plantations.

Many decades later, the message and spirit of Arbor Day had spread throughout the world. In 1977, Kenyan political and environmental activist Wangari Maathai started a grassroots movement known as the Green Belt Movement. It organized women in rural Kenya to plant trees in order to combat deforestation and erosion and provide future food and firewood, all the while empowering the women involved. The movement has planted over 50 million trees, and tens of thousands of women have received training in environmentally sustainable trades. Maathai received the Nobel Peace Prize in 2004.

One of the most inspiring stories about people and trees comes out of India. In 1979, a local teenager named Jadav Payeng began noticing that on the island of Majuli, his home, erosion was taking vegetation and land away, and many of the native animal species along with it. Majuli is the largest river island in the world, located in the middle of the Brahmaputra River, and is vulnerable to the tides of many tributaries. Seasonal flooding was leaving large areas of the island barren, while washing other areas away completely. Payeng was concerned by what he saw, so he planted twenty bamboo seedlings on a sandbar to help prevent this erosion from continuing. He was so inspired to save his home in this way that he continued to plant trees and scatter tree seeds to help reforest the island. Today, he is responsible for planting a forest that is now approximately 1,400 acres, more than one and a half times larger than New York City’s Central Park! Deer, tigers, rhinoceroses, and elephants have moved into the dense forest, along with returning bird species that had not been seen in the area for decades.

This Arbor Day, let’s be inspired by these stories of how individuals can make a large and lasting impact on our world. If you can, plant a tree (or several), care for the trees that you already have, or volunteer for a neighborhood tree advocacy group. We can all make a difference and improve our world with trees!

Smithsonian Gardens Receives Grant Award to Fund a Water Conservation Project

In honor of Earth Day, Smithsonian Gardens is proud to announce a $146,200 grant award from Smithsonian Institution’s Collections Care and Preservation Fund for a water conservation project at our Suitland Greenhouse Facility.  The award supports the purchase and installation of a rainwater harvesting system to irrigate the Smithsonian Gardens Orchid Collection by collecting and using rainwater to water the collection rather than municipally-treated water as we use now. This project is a collaboration between Smithsonian Gardens and the Smithsonian Facilities Energy Management Branch of the Systems Engineering Division which is responsible for Smithsonian’s energy use and conservation techniques.

Rainwater harvesting is a technique used for collecting, storing and using rainwater for landscape irrigation and other uses. The rainwater is collected from hard surfaces such as rooftops and is a cost effective method of water conservation.  Rainwater is superior for plant watering because it is free from pollutants like dissolved salts, minerals, and chemicals such as fluoride and chlorine.

Water quality is of critical importance when it comes to successful orchid cultivation and maintenance. Orchid species exposed to municipal water often show detrimental physical manifestations caused by accumulated salts building up in the orchid growing medium. These adverse effects include leaf tip burn, decreased plant vigor, reduced blooming, discoloration, and even death.

Many of the best orchid collections and commercial growers in the United States, Europe, and South America use either purified water or rainwater for irrigating orchids. Switching from municipal water to rainwater is like ‘flipping a switch’ with regard to orchid growth. Seedlings irrigated with rainwater grow two to three times faster and the plants often have cleaner, unblemished foliage. A resent comparison of Atlanta Botanical Garden seedlings sired at the same time as ones grown by Smithsonian Gardens Orchid Collection show they are more than triple the size of those being grown by Smithsonian Gardens. Clear evidence of the need to implement better water quality for the over 8,000 orchids in our collection. We hope to have the new water harvesting and irrigation system installed by the end of this year.

This project celebrates innovation and supports sustainable collections care which will have a direct, substantial, and permanent impact on the health and preservation of the Smithsonian Gardens Orchid Collection. This project received Federal support from the Smithsonian Collections Care and Preservation Fund, administered by the National Collections Program and the Smithsonian Collections Advisory Committee.

A Floral Firework Display: What’s Blooming in the Smithsonian Gardens Orchid Collection

Sunday is the final day of the 2016 orchid exhibit, Orchids In Focus, at the United States Botanic Garden (USBG). It has been an interesting season to say the least, with seventy degree weather in January and gusting winds throughout March. Most of our show plants are bloomed out and will start their recovery for next year’s blooming cycle. Our species orchids are not on such a rigid schedule and are still living the slow life in the greenhouses, blooming when they please and offering visual fireworks of color amidst the overwhelming background of green foliage.

Scaphyglottis bidentata is a dazzling miniature orchid from Central and South America. This species exhibits spectacular red-orange flowers, a pollination syndrome for ornithophily, or bird-pollination. Several other Scaphyglottis with large (relatively), bold flowers were previously classified under a distinct genus, Hexisea but were morphologically similar enough to the former Scaphyglottis grouping to be lumped together. One of the major defining morphological characteristics of species in this group is that the pseudobulbs are stacked (see inset photo).

Another striking pop of color found in our species greenhouse comes from Dendrobium bracteosum var. tannii. If you look this one up, you won’t find tannii mentioned anywhere because the name has never been formally published. This variety is a miniature form of the species. To give you an idea of the size difference the flowers on our specimen are no longer than a centimeter in diameter, which is less than half of the typical size.

Dendrobium sanguinolentum is a pendant growing epiphyte found in Thailand, Western Malesia and the Philippines. This species is known as “The Blood Stained Dendrobium” because the flowers typically have splotches or stains of violet at the edges of the sepals and petals. The plant below may be an alba form of this species since there are no stains evident on the pale yellow flower.

This week’s grand finale is Myrmecocattleya Claudia Elena. This fantastic hybrid with such vivid coloration is a cross between Myrmecophila tibicinis and Cattleya dowiana. In the wild, the ranges of these two species do not overlap, but since they are both part of the Cattleya alliance, hybridizers are able to successfully interbreed them. Myrmecophila flowers are typically one to two inches in diameter, but when crossed with a large flowered Cattleya, they almost triple in size!

Photographs are a wonderful way to explore nature’s diversity, but nothing compares to experiencing it in person. If you are in the Washington, D.C. area, make sure to take a final trip to the USBG to see our orchids on display before the exhibit ends on the 17th!

Preserving Our Garden Heritage One Pixel at a Time

What better way to celebrate National Garden Month in April than to spend some time enjoying historic garden images from the J. Horace McFarland Company Collection!  Thanks to a Smithsonian preservation grant, thousands of images from this collection at the Archives of American Gardens (AAG) were digitized recently and are now available online through the Smithsonian’s Research Information System (SIRIS).  These images–produced by McFarland’s publishing firm which specialized in printing horticultural publications–are just some of the treasures found in AAG which is administered by Smithsonian Gardens and tasked with collecting historic and contemporary garden documentation as a means of preserving our garden heritage.

Very much a renaissance man, J. Horace McFarland (1859-1948) of Harrisburg, Pennsylvania,was a publisher, author, lecturer, horticulturist and authority on roses.  As the first President of the American Civic Association—a position he held for 20 years—McFarland also advocated for effective civic planning and improvements throughout the U.S. during the Progressive Era (1890-1920) when living and community conditions called out for significant reforms.

McFarland’s printing company, Mount Pleasant Press, published many of the seed and nursery trade catalogs in the U.S. during the first half of the 20th century.  The J. Horace McFarland Company Collection at AAG includes over 3,000 of the firm’s images, many of which were published in books, catalogs, newspapers, and journals.

The images document an extensive variety of gardens across the U.S. dating from the 1900s to the 1960s, everything from popular parks to small flower patches planted behind crowded urban row houses.  Thanks to the broad range of private and public gardens photographed by the firm, the J. Horace McFarland Company Collection provides glimpses into historic trends and events of the times including World War II’s victory gardens and post-war neighborhood development.  Images that show people working in or enjoying these gardens are especially captivating.  In many cases the photographs are the only evidence left of certain gardens and public spaces.

This digitization project was timely since the photographs—which had been pasted onto brittle cardboard mounts –are fragile and subject to continued deterioration.  Rather than scanning the thousands of photographs on a flatbed scanner—both a time-consuming and potentially damaging procedure—each was photographed with a Phase One digital camera under controlled lighting conditions.  High resolution digital images are now readily available for research use and the need to handle the originals has been significantly reduced.  We hope you get a chance to search the McFarland Company Collection online and enjoy the garden history that it documents.
