Her Majesty gave her grandson the royal seal of approval as she visited his garden yesterday (18.05.15), designed by Matthew Keightley for the Prince's charity Sentebale to mimic the look of Lesotho, the country in which it helps vulnerable, HIV positive children.

Aides said Prince Harry had been "extremely nervous" as he waited anxiously to show his grandmother around the garden, but the Queen was very complimentary.

The charity's chairman, Philip Green, who accompanied the group, said: "Prince Harry was beyond nervous at what his grandmother's reaction would be but she was delighted.

"The Queen was hugely complimentary about the planting and very knowledgeable about the charity and what it is trying to achieve."

The Prince guided the Queen around the garden, which featured a moving series of footprints made from casts taken from some of the children that Sentebale has helped, and were soon joined by Harry's father, Prince Charles, and step-mother the Duchess of Cornwall, and later by Prince Philip, his grandfather.

Phillip Green told the MailOnline: "I would say that Harry was even more nervous about his father's reaction. The Prince of Wales is obviously a very keen and talented gardener himself.

"Prince Harry was genuinely thrilled - and not a little relieved - at his reaction. There is a genuine closeness between Prince Harry and all his family. And they made clear how pleased they were for him and how proud."
