Green (un)seen

We are so happy you are reading this!

It means you’ve found one of our Green (un)seen “love” letters  — quietly spread across various cities around the world. Berlin, Malmö, Zurich, New York, Barcelona, Trondheim… and now in your hands.

Take a moment to arrive at our invitation.

To pause. To reflect. To notice.

To see plants not as the background of your daily life, but as the foundation of the living world you are part of.

Join us in celebrating Fascination of Plants Day, 18 May 2026  🌱

Connect with people across the globe who, like you, found our enveloped message in a public space. 

We invite you to:

• Reply in the comments below to the question you found in the letter. 

• Tell us where you found  the letter - city, country, exact place (ie. library, train station, shop, etc - and when,

• Share a photo of the place where you found it, if you can.

• ...and if you wish, your name.

Then pass the message on. Leave the letter in another spot in your city, where someone else might find it and join us. Let it travel from place to place, carrying the reminder that plants are not just a background of our lives, but the living foundation of ecosystems, food systems, climate, and our shared future.

We hope this small local - yet - global gesture can inspire reflection, respect, and more mindful choices for a greener, more caring future.

Your Green (un)seen team,

Anabella, Sylwia and a growing community brought together by a shared fascination with plants
