Adam Frost and Angellica Bell present an exclusive preview of the RHS Chelsea Flower Show, from the grounds of the Royal Hospital Chelsea.

There are show gardens inspired by Florence Nightingale and Psalm 23, feature gardens helping tackle climate change, a Kew wedding that becomes a floral celebration, a nursery that is exhibiting a whole new collection of plants, and a school where students prove the value of houseplants.

Nicki Chapman and Angellica Bell have exclusive access to the long-awaited opening day of this year's RHS Chelsea Flower Show. On a VIP-packed press day, Nicki chats to Lisa Snowdon about her love of gardening, and James Wong hunts out the best houseplants. Frances Tophill tells you everything you need to know about building your own Insta-Pond, and Mark Lane takes a first look at the Great Pavilion.
