The Calyx (pron. kal-iks) is defined as ‘the sepals of a flower, typically forming a whorl that encloses the petals and forms a protective layer around a flower in bud’.

The Calyx is the Garden’s new world-class attraction featuring horticultural exhibition that opened on 11 June 2016 to celebrate the Garden’s 200th Birthday.

Think of it as both a living art gallery and a theatrical experience that houses ever-changing living botanic exhibitions. The Calyx is a place to inspire and capture imagination, an enchanting and magical experience where plants will take you on a journey of discovery.The Calyx is a contemporary and engaging experience set within the beauty and tradition of the Garden aiming to inspire a new generation of advocates for plants and the environment, transforming the view of the natural world.The whole space is an integrated mix of indoor and outdoor areas with the exhibition changing dramatically each year, reinventing itself through emotively themed exhibitions changing every nine months.Construction of the building took just over 11 months and the highest point inside the building is 5.5m!
