Sometimes I think about the secret nighttime lives of plants. Do they “sleep” at night? What do they devote their energies to when they’re not photosynthesizing? What about urban plants in the city that never sleeps? Do they lead social lives? Do they hang out together and live it up while we’re not watching?
When I started taking night shots my attention was drawn to the strong presence of the street lights in the photographs. This got me to thinking, are these plants really able to rest during the night? Does light pollution affect city plants? Online resources relating to this question appear scarce, but the one article I did find is from a study showing the effects of street lamps on trees in New York City from 1936! Unfortunately, only the first page of this article and the abstract are available for free. But it’s enough to encourage further contemplation and research.
Also, I was excited to discover a tiny NY Times article from 1894 in my online search for “plants” and “sleep” titled, appropriately, The Sleep of Plants. I had no idea that the NY Times Archives went back so far!
