Building a Wardian Case

with Janneke de Lange

7 Jul 2024

Designer Janneke de Lange envisions a future scenario in which she can grow her own tropical fruit trees in a mobile plant greenhouse, a 'Wardian case'. Join us during the Japanese Knotweed Season, craft your own unique piece, learn how to cut glass and build a small glass dome design by Janneke specially for this workshop!



Fruiture Nursery - Frontal View of the Installation - These are the Wardian case inspired vehicles for plants that Janneke de Lange is showing in Amsterdam in the Spring of 2024. The exhibition is part of the annual Japanese Knotweed season program at Mediamatic.   Vu Ha

What will you do 

Because the Dutch climate is not suitable for fruit trees such as mangoes and papayas, we are dependent on expensive and environmentally harmful international trade. The Netherlands has a long history of bringing botanical specimens to Europe from all over the world and is still central in the trade of decorative plants. Janneke asks us what we can design to envision a future on a smaller personal scale. Join designer Janneke de Lange in this workshop and learn how to make your own mobile plant greenhouse!

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.


Glass Dome - With lighting inside - "FRUITURE NURSERY", by Janneke de Lange Janneke de Lange


Janneke de Lange

Janneke de Lange is a designer who graduated from Design Academy Eindhoven. Her work "FRUITURE NURSERY" will be displayed at Mediamatic during Japanese Knotweed Festival 2024.

The project "FRUITURE NURSERY" is a blend of two passions: greenhouses and tropical fruits. Since childhood, I have been in love with greenhouses, particularly botanical gardens, they are magical to me. Stepping into a glass palace on a chilly day transports me to another reality—a carefully curated jungle filled with thick, warm tropical air and the intoxicating scent of greenery and moist soil.
