In 2018, BBC News highlighted the problem of the Floating Pennywort, an aquatic plant choking the waterways in the UK. Around 96km of the River Soar and River Trent in Leicestershire and Nottinghamshire have been choked by this invasive plant. The pennywort was first identified in Leicestershire in 2004, where it was thought to have escaped from a private garden, quickly growing uncontrollably in nearby waterways and outcompeting native plants.

The pennywort can grow up to 20cm a day, blocking out light for other aquatic plants. As the growth proliferates throughout the spring and summer, the river becomes choked and slow flowing, leading to increased levels of siltation in sensitive habitats, such as fish spawning areas. Large volumes of pennywort can reduce oxygen levels while decomposition at the end of the growing season can impact water quality, harming fish, plants, and river fly species that require good water quality to survive. The problem is so serious that the Environmental Agency of Leicester has sprayed herbicides and removed the plants every year since 2007 and regularly since 2010.

This project uses archival and original images to make cyanotype prints directly onto the pennywort plant, recreating the pennywort proliferation and visually mimicking its matted density water bodies.
