The Solitary Garden

posted by Jason Kottke   May 21, 2019

In 1960, David Latimer put some compost, water, and plant seeds into a large glass jar and sealed it up. And it’s been growing like that ever since, save for when Latimer opened the bottle to water it in 1972.

Bottle Plants

It’s easy to take nature and evolution for granted but think about how marvelous this is. Over billions of years, an ecosystem evolved on Earth that can sustain itself basically forever using light from the Sun.

The plant creates energy from the sunlight via photosynthesis, using up carbon dioxide and releasing oxygen into the bottle. When parts of the plant die, bacteria in the soil use the oxygen to break down these dead parts, releasing carbon dioxide and completing the circle. The water cycle is similarly self-refueling: whatever water the plant takes in through its roots ultimately transpires out of its leaves, condenses on the inside of the bottle, and drips back into the soil.
