Join us this Saturday, May 9th, from 10 a.m. to 3 p.m for a celebration of “Water, Water, Everywhere” at Garden Fest in the Enid A. Haupt Garden. In this blog entry Sarah Tietbohl writes about just one of the many ways we try to conserve water at Smithsonian Gardens.
When I first started at Smithsonian Gardens in 2010 I was assigned the job of cleaning the Moongate fountain in the Enid A. Haupt Garden. I was excited about this task as I would have an opportunity to learn to use a new piece of equipment and keep cool during the hot summer months. I estimated that the fountain would need to be cleaned maybe once a month. With the pond open between April and October, that would total seven times a year. That spring, the cleaning schedule started out at once a month. As the season went on and the temperatures climbed into the 90s, I noticed that the fountain was growing algae at a rapid pace. It turned the water a sickly slimy-green color. That once-a-month cleaning turned into scouring once or twice a week! That season, I ended up cleaning the fountain well over twenty times. The next year it was the same story.
After the summer of 2011, I really started to think about all of the water, energy, and time it takes to clean the Moongate fountain. I started to gauge the amount of water that was being used in one year to clean and fill the fountain. I calculated that it takes 2,300 gallons of water just to fill the fountain each time it is cleaned, plus 200 gallons or so to clean it. I decided to research environmentally-friendly products that would reduce the amount of algal growth, thereby cutting down on the amount of water needed to re-fill the fountain after each cleaning. Fewer cleaning sessions would also result in less emissions (and noise) generated from the power washer that runs every time the fountain is cleaned. I started experimenting with a non-toxic black pond dye. Adding black dye to the fountain reduced the amount of sunlight that was able to penetrate the water, which in turn reduced the algal growth. I found the dye to be very effective and talked my colleagues into using it in the fountains in the Ripley and Folger Gardens as well. Thanks to the black dye solution, Smithsonian Gardens has reduced fountain water use from 60,000 gallons a year to slightly less than 22,000 gallons- a terrific way for Smithsonian Gardens to employ a sustainable alternative in its operations.

Like any number of inventions, the origins of the armillary sphere are debated, credited to everyone from an ancient Greek philosopher to a Roman mathematician to a Chinese astronomer. The one commonality: it was created with the faulty supposition that the earth was the center of the universe!
Armillary spheres served as a model of the heavens with intersecting rings marking everything from latitude and longitude to the tropic of Cancer. (No wonder the name was derived from the Latin word ‘armilla’ meaning bracelet or ring.) Early spheres were fabricated out of wood but as they became more complex they were made of brass which withstood the elements out of doors. As with most objects of science, armillary spheres progressed as new discoveries were made. The Chinese used them to make calendar computations and calculations. During the Middle Ages, they served as sophisticated instruments used to map the solar system. Soon rings were added to mark the equator and the rotation of the sun, moon and known planets, making these spheres some of the first complex mechanical devices.
Because they were used outside where the sky was visible, armillary globes have become a common decorative feature in gardens. Today’s armillary spheres for garden use are strictly decorative in nature and much more streamlined than their ancient counterparts (think fewer rings inside the globe). While they no longer serve as a way to monitor the stars, they remain a symbol of progress and ingenuity throughout time.
Garden trends seem to be forever changing. Some develop because even gardeners who stick with a roster of proven reliable plants like a change now and then. There are, however, numerous trends that last. For example, Penjing, or the art of depicting landscapes in miniature, is an ancient pastime that developed in China and is still seen by the use today of bonsai plants. One interesting trend currently emerging out of these gardens in miniature is what’s known as a “fairy garden.”
Lemon Hill’s fairy garden is composed of young plants, diminutive trees and bonsai that are in scale with its miniature castle and houses, fountain, stone walls, gates and furniture, and fairy figurines. The Fairy Garden takes its name from the Meyer lemon trees grown in the vicinity. Its design was inspired by miniature gardens found in Ireland and in books. It is visited often by school and scout groups.
Though gardens can reflect many things, such as taste and style, they can also reflect function, such as creating a special place for children and grandchildren. Just look at the Fairy Garden on Lemon Hill. Lemon Hill was a special project for the owner and her grandchildren. Her own daughter helped her build the garden and she implemented suggestions from her other three daughters as well as her 13 granddaughters. She created the garden with all her girls in mind.
Building a fairy garden can be a project that you enjoy with your children or grandchildren that can get them excited and participating in the art and act of gardening. They can be found in any number of small spaces, such as bird baths, pots, or large plant saucers.
