The Queen and celebrities are getting the first look at this year's Chelsea Flower Show today, before the world famous gardening show opens its doors to the public.

The effects of old and modern conflicts are being remembered in horticulture as the show marks the centenary of the First World War.

Designers have drawn on family experiences of war from the Somme to Afghanistan to create displays for this week's event at the Royal Hospital Chelsea.

The flower show also contains gardens addressing themes from fashion to sustainability and drawing on inspiration from around the world.

UK growers - including some who battled floods for weeks in Somerset at the beginning of the year - are showcasing their produce, while one herb grower has recreated the vegetable garden where Peter Rabbit liked to eat.

And veteran Chelsea BBC presenter Alan Titchmarsh has returned to his gardening roots with a garden that celebrates 50 years of the Royal Horticultural Society (RHS) Britain in Bloom competition - and his 50 years in horticulture.
