Mushrooms are having a moment, and this year, visitors to the RHS Chelsea Flower Show will have the chance to experience their magic up close.

After winning multiple RHS Gold Medals for our immersive mushroom exhibits, we're returning to Chelsea Flower Show with our most ambitious display yet: Beyond the Button – Exploring the Diversity of Fungi.

As one of the UK’s leading specialists in home-grown edible and functional mushrooms, Caley Brothers was founded by two sisters with a passion for sustainability, food innovation and reconnecting people with nature through fungi.

“Our mission is to demystify the world of mushrooms and inspire people to grow their own at home. We believe mushrooms hold the key to a healthier, more sustainable future - and this year’s exhibit is designed to show visitors exactly why.”

For decades, the humble button mushroom has been a kitchen staple, finding its way into everything from comforting stews to simple omelettes. But the world of fungi is vast, vibrant and full of extraordinary diversity - and Beyond the Button invites visitors to explore it.

This year’s exhibit celebrates mushrooms beyond the familiar, showcasing everything from oysters and shiitake to coral tooth, cordyceps and a fascinating range of native UK varieties. 

A mossy backdrop, layered with sustainably sourced moss from the Highlands of Scotland, gentle drifting mist and flourishing mushrooms showcased in frames, will transform the space into a living fungi experience. In keeping with our sustainability values, the exhibit eliminates the use of peat, plastic and polystyrene throughout the build.

But Beyond the Button is more than a visual display - it’s an invitation to engage with the future of food, sustainability and regenerative growing.

Whether you’re a gardener, grow-your-own enthusiast, food lover, forager or simply curious about the role fungi play in our ecosystem, the exhibit offers a chance to discover how mushrooms can support biodiversity, sustainable living and healthier diets.

Visitors will also be able to learn how easy it is to grow mushrooms at home and explore the growing movement around edible and functional fungi. From forest floor to fork, the exhibit aims to inspire a deeper appreciation for mushrooms and the important role they may play in shaping a healthier future for people and the planet.

This year, we are proud to once again be supported by Grass & Co., whose continued sponsorship reflects a shared belief in the power of functional mushrooms and natural wellbeing. And Highland Moss who will be joining us at the show to showcase their first class, sustainably grown and sourced natural, peat free moss.  Together, we hope to encourage more people to explore the extraordinary benefits and potential of fungi.

With creativity, sustainability and innovation at its heart, Beyond the Button promises to be our most immersive and impactful Chelsea exhibit yet - celebrating the beauty, diversity and future of mushrooms in a way visitors won’t forget.
