What will you do

Have you ever wondered what secrets lie beneath the surface of a plant? The unassuming Japanese knotweed, while often considered a nuisance, boasts a surprising range of vibrant colours hidden within its roots (rhizome). In this unique workshop, you'll transform wool using these natural dyes, creating your own personalised colour palette. Guided by Lucie's expert techniques, you'll explore the art of natural dyeing with Japanese knotweed. Learn how different parts of the plant yield unique hues, and unlock the hidden potential of this often-overlooked resource.

Build on your skills! This workshop is designed for experienced participants, offering in-depth exploration and the chance to create a wider range of colours.

Japanese Knotweed Season 2024

Every spring, Mediamatic organises a season around Japanese knotweed. Knotweed is a fast-growing plant known in Europe for being considered invasive. What many do not know, however, is that this plant species has a host of positive properties. During this season we will explore how to live in harmony with this controversial plant.

Lucie Havel

Lucie Havel is an artist fascinated with the way humans relate to nature. This has become the main focus of her work. It started as an interest in the deities and rites of tribes that do not hold the dichotomous belief system of humans versus nature. After two years of research that garden “weeds” started calling her attention. For her they symbolise the successfully untamed and non-functional entities. That is how she discovered the incredible abilities of the Japanese knotweed.
