Japanese Knotweed Festival

love your guest

Mediamatic is hosting an immersive 3-week festival around Japanese knotweed, which will recur the coming 3 years. Japanese knotweed is a fast-growing plant known in Europe for its invasive and intrusive characteristics. Many do not know that this species has many positive attributes ranging from its delicious taste and medicinal properties to its potential for being the base of biomaterials.

The Japanese Knotweed Festival investigates how, in collaboration with various creators, we can contribute to a way of living together in harmony with this contested plant.
