ONTARIO, CA — Local man Nathan Williams reportedly told his wife he'd be happy to hear more about their house being on fire just as soon as a helicopter finished passing by.

A Bottled Garden, 66 Years Strong

On Easter Sunday in 1960, British hobbyist David Latimer placed a few cuttings of spiderwort (Tradescantia) into a globular ten-gallon glass carboy with a bit of compost and a quarter-pint of water. He sealed it with a greased cork stopper and set it near a sunlit window.

In 1972, twelve years into the experiment, Latimer opened the bottle to give the plant its second and final drink of water. He sealed it again, and it has stayed that way ever since.

More than 66 years after planting, the carboy remains the world’s longest-living closed terrarium (Tropical Glass, Wikipedia).

Does It Still Exist?

Yes. The sealed bottle garden continues to thrive. Aside from occasionally rotating the vessel so all sides receive indirect sunlight, Latimer has left it completely untouched.

He has noted plans to pass the heirloom down to his children, or donate it to the Royal Horticultural Society so it can continue to be preserved and studied.

The Science of a Closed World

The carboy requires no fresh air, no fertilizer, and no added water. The only external input is light:

• The Water Cycle: The plant drinks through its roots, releases moisture through its leaves via transpiration, and lets condensation gather on the glass walls to rain back down into the soil.
• The Carbon Cycle: Photosynthesis produces oxygen and sugars by day. At night, plant respiration and soil bacteria breaking down fallen foliage consume oxygen and release carbon dioxide, feeding the next morning’s growth.

It is a complete, self-regulating biosphere running on a continuous loop.
