Moss graffiti is a recent trend in street art that uses living moss to write on the walls of public spaces. Moss can be blended and painted onto a wall, and may then grow in position. By replacing the harmful chemicals found in paints (such as methanol, which damages the nervous system when consumed in large quantities ) with plant matter, the artist can still create works without damaging the environment. After application, the moss grows, adding a new dimension to the art medium as well as extending the concept of guerrilla gardening.
Making and applying moss graffiti
Moss graffiti is created by taking clumps of moss and blending them with water (sometimes beer), buttermilk, yogurt, and corn syrup to create a thick, paintable liquid. Using a paint brush, the moss mixture is painted on a wall in the desired pattern and allowed to grow. More applications of the moss mixture or water may be needed to create a fuller effect.
