David Latimer planted a bottle garden in 1960 and shut the opening down after watering it for one last time in 1972. The garden continues to have lush green plants in a sealed environment by itself without any water, moisture and fresh air.

It has a miniature ecosystem thriving with a low maintenance of sunlight alone!
