David Latimer’s Terrarium
In the picture above is one of the longest surviving terrariums. It is made and designed by David Latimer who is a retired engineer. We might think that the plants in his terrarium are non-flowery but they are in fact flowery spiderworts – as shown in the picture below.
The Terrarium Ecosystem
What exactly is a terrarium? A terrarium is basically a self-sustaining garden in a bottle. So yes! You guessed it right. It requires very low levels of maintenance. This is because of 3 processes:
- Photosynthesis: This allows the plant to release oxygen by taking in sunlight, water and carbon dioxide.
- Respiration: The plant releases carbon dioxide after taking in oxygen and water.
Hence we do not need to unseal our terrarium. Reason being that there is continuous gaseous exchange of oxygen and carbon dioxide!
- Water cycle: In the terrarium, the plant releases water vapor through its leaves. This is known as transpiration. Water vapor then condenses and form droplets along the walls of the bottle and the droplets fall back into the soil to be reabsorbed by the plant.
Now you might be wondering, ‘Is Mr Latimer’s terrarium still alive?’ Well the answer is a surprising ‘yes’. In fact, it has already survived for a total of 58 years! According to Latimer & the ‘daily mail’, he planted it in the year of 1960 and left it sealed up for a total of 12 years. Thinking that the spiderworts are getting drier, Latimer added only 140 grams of water in 1972. http://www.dailymail.co.uk/sciencetech/article-2267504/The-sealed-bottle-garden-thriving-40-years-fresh-air-water.html. After doing so, he left the bottle sealed till this very day.
1960 – 2018: 140 Grams Of Water
That’s really fascinating isn’t it? The fact that David has only maintained it once by adding only 140 grams of water between the years 1960 – 2018! Now it might even live longer than Mr. Latimer himself! If that happens, he has plans to either pass it on to the Royal Horticultural Society or his children. Here’s a video of David Latimer with his bottled garden:
