Entire TV shows these days are dedicated to tiny houses, so perhaps it should come as little surprise that mini-gardens are popular again.
Growing plants in transparent containers dates to Greece at least 2,500 years ago, according to University of Missouri Extension. The practice in the United States is traced to New England.
“The invention of the terrarium as we know it is credited to Dr. N.B. Ward, a 19th-century London physician. … While studying a sphinx moth emerging from a chrysalis he had buried in moist earth in a closed bottle, he was amazed to see a seedling fern and some grass growing inside. He watched them grow for four years, during which time not one drop of water was added nor was the cover removed.”
Closed terrariums are best at keeping humidity inside (followed by open terrariums and dish gardens), so they only have to be watered once per week. Terrariums and plants are great for offices as they are known to improve air quality, boost productivity and reduce stress.
