Prince William and Harry have paid tribute to their mother Princess Diana with a visit to her memorial garden at Kensington Palace on the day before the 20th anniversary of her death.

The royal brothers were joined by the Duchess of Cambridge on a tour of the Sunken Garden, which has been transformed into the White Garden in Diana’s memory this summer.

Head Gardener Sean Harkin led the royals on a walk around the grounds and pointed out a number of Diana’s favourite flowers on the way, from lilies to white roses.

During the visit, the princes also met with representatives from some of the main charities Diana supported, including Great Ormond Street Hospital, the National Aids Trust, the Leprosy Mission and the English National Ballet.

According to Harkin, the Sunken Garden was one of Diana’s favourite spots in her former home.

“The Sunken Garden is the jewel of Kensington Palace and it was a particular favourite of Diana’s,” he explained to Country Living. “In the mornings, she would go out for a jog and would stop by the garden and have a chat with Graham and the gardeners. She would say how much she liked the garden and comment on what it was looking like depending on the seasons. She would have a bit of a joke with them and was really friendly and warm.”
