The detailed blueprint of the garden created by the 28-year-old Prince for this year's Chelsea Flower Show, to be held here in May, were released by the Sunday Times today.
The "forget-me-not" garden includes his mother's favourite "hearts and crowns" motif on an elaborate stone-worked terrace and a plant called "William", the same name as his elder brother.
The Prince had chosen designer Jinny Blom to work on the exhibit for his charity Sentabele, set up in the name of his late mother Princess Diana to help HIV positive children in Lesotho, Africa.
Blom, who has used native flowers of Lesotho around a traditional roundhouse, had emailed the designs to Prince Harry and he sent back his thoughts from Camp Bastion in Helmand province in Afghanistan, where he is serving on the frontline as a helicopter co-pilot.
"Forget-me-nots were a given, and beyond that he said 'over to you'," Blom said, adding that Harry really likes the designs so far.
The garden, which has been paid for with sponsorship from British building retailer B&Q, will also feature a traditional conical wooden house similar to those found in the mountain kingdom of Lesotho.

"It's all about circles. They have circular houses, they have circular hats; the houses and the hats both look like each other and they in turn look like the hills," Blom said, in reference to the garden which will open to the public at the Chelsea Flower Show, one of London's premier summer events.
Prince Harry, who has been known in the past for his partying ways, had set up the African charity back in 2006 to carry on his mother's work in the field of helping children affected by AIDS.
