Plant survives 50 years locked in a bottle A plant sealed into a large glass bottle more than 50 years ago is thriving, having created its own miniature, self-contained eco-system. Its owner, David Latimer, began his experiment in 1960 when bottle gardens were all the rage, curious to see how well the plants would do. He planted four species, of which only one survived, but that is going strong, despite having been deprived of fresh air or moisture since the bung was last removed in 1972.
