Organisers of this year's Chelsea Flower Show are hoping this year's theme will come up roses with contestants, who are being asked to cast their eye over history for inspiration.
The Chelsea Flower Show will mark the centenary of the First World War by asking entrants to arrange flowers around the theme of old and new conflicts.
Designers have drawn on family experiences of war from the Somme to Afghanistan to create displays for this week's show at the Royal Hospital Chelsea.
No Man's Land: ABF The Soldiers' Charity Garden to mark the centenary of the First World War represents a landscape marked by the fighting in northern France, including trenches, a mine crater pond and the yew trees found in war cemeteries.
Broadcaster Alan Titchmarsh has admitted he was "hurt" by the BBC's decision to sideline him in this year's Chelsea Flower Show programming - saying he was made "an offer I had to refuse", he told the Radio Times.
Titchmarsh, 65, who has been replaced by Monty Don admitted:
"Yes, I suppose I was hurt, because I know people enjoy you doing it as much as I loved doing it.
"But they probably felt it was time for a change and may well be right. Was I dumped for Monty Don? You might say that. I couldn't possibly comment. I don't feel dumped."
It was announced last year that Titchmarsh was leaving the show, with the BBC saying in a statement: "The way the Chelsea coverage will be presented across the BBC has changed for 2014, and Alan decided to step away from next year's show."
Titchmarsh told Radio Times: "I'm not bitter. I was disappointed but I'm not a grudge-bearer. You have to move on."
This year, Titchmarsh has created a Royal Horticultural Society (RHS) garden for Chelsea and the BBC has booked him for an interview to talk about his creation for the Britain In Bloom scheme.
