Chelsea Flower Show is set to explore new territory this year with first ever underwater garden

The Chelsea Flower show will explore new territory later this year by featuring the first underwater garden in its 111-year history. The Seawilding Garden will feature the world’s only flowering sub-aqua plant – seagrass. The marine plant will feature in a 3,000 litre (660gallon) visible to visitors through the walls of a perspex tank.

Underwater gardens have featured in song, such as the Beatle’s Octopus’s Gardens and TVs in the adventures of Spongebob Squarepants. But they have never featured at the RHS event before – and never before have gardeners had to use snorkels to cultivate a Chelsea garden.

The UK has lost around 95 per cent of our seagrass meadows but efforts are under way to bring it back around Britain’s coasts. And after the show the seagrass will be replanted underwater, helping to mark the first time a Chelsea Garden has gone on to become an underwater habitat.

While little known to many of us the plant is an unsung hero in the battle against climate change and in supporting fish and other marine life who shelter in it. The Seawilding Garden (pictured) will feature the world’s only flowering sub-aqua plant – seagrass.
