The Duke and Duchess of Cambridge and Prince Harry visited the White Garden at Kensington Palace on Wednesday to commemorate the 20th anniversary of Princess Diana's passing.

The White Garden is a floral tribute to the late Princess at her former home. Kensington’s Sunken Garden was transformed over the last year and, according to Vogue, the original flora was donated to local hospitals and replaced with what would become a stunning white vista.

Gardener Sean Harkin, who knew Diana back when she lived at the residence, chose white due to its recurring theme in her life. The hue popped up everywhere from photo shoots to her famous "Elvis dress" to the flowers that marked her casket.

The Royals spent a rainy day touring the garden that their mother once loved so much. They also visited a makeshift tribute at the Palace gates where mourners, who still haven't moved on from losing "The People's Princess," are placing flowers and cards.
