Chelsea Flower Show 2025 to feature underwater garden
The RHS Chelsea Flower Show 2025 will feature an underwater flowering plant for the first time.
The Seawilding Garden, designed by award-winning Ryan McMahon of MUSA Landscape Architecture, will feature seagrass, the ocean's only flowering plant.
Inspired by the shores of Loch Craignish in Argyll and the restoration efforts of Scottish charity Seawilding, the garden will highlight the actions taken by a remote rural community to reverse biodiversity loss by restoring keystone species seagrass (Zostera Marina) and native oysters (Ostrea edulis) to their waters.
Seagrasses can live in seawater and pollinate while submerged. Unlike seaweed, seagrass behaves like a real plant, shedding its leaves in autumn and growing new ones in spring.
The Chelsea garden will feature a saltwater pool, stone pathways, a pebble beach area, native trees, seating, and a 2.5m high seagrass sculpture made from recycled scrap metal.
"As a keen ocean swimmer, with a love for our natural environment, I always assumed seagrass grew in warmer climates. But when I learned through Seawilding that it grows in our coastal seas, I was intrigued. The more I discover about seagrass, the more fascinated I become by the incredible role it plays in our marine ecosystems," says garden designer Ryan.
"I've long admired the important work of pioneering marine restoration charity Seawilding, having first learned about their work via social media, so when the opportunity arose to create a show garden for the RHS Chelsea Flower Show supported by Project Giving Back, they were my first choice."
Hattie Ghaui, CEO of Project Giving Back, adds: "Biodiversity loss is a critical global challenge, and seagrass, the ocean's only flowering plant, plays a key role as a habitat for marine life and a vital carbon sink.
"Sadly, 95% of the UK’s seagrass meadows have vanished due to disturbance, pollution, and disease. Seawilding's groundbreaking restoration work at Loch Craignish empowers communities to restore coastal waters by reviving seagrass and native oyster beds, delivering lasting, measurable impact. We hope this garden inspires others to help protect and restore our precious marine ecosystems."
The Seawilding Garden will feature in the All About Plants category inside the pavilion at the Chelsea Flower Show.
