King Charles and Queen Camilla are putting down some royal roots with King Carl XVI Gustaf of Sweden and Queen Silvia of Sweden.
On May 1, the royal couples came together for a rare joint duty and planted a tree together in the Home Park of Windsor Castle.
The sapling was planted in celebration of the coronation of King Charles, 76, and Queen Camilla, 77, at Westminster Abbey on May 6, 2023, and the tree planting happened just a few days before the second anniversary of their crowning ceremony.

King Charles and King Carl Gustaf both used shovels to move dirt from a pile onto the tree sapling. The Swedish monarch used a special spade with historical significance: in November 1908, Sweden’s King Gustaf V used the same shovel to plant an English oak tree in Windsor Great Park.
The commemorative tree is a Swedish oak (Quercus robur) tree and was given as a gift from the King of Sweden. The oak is from the Royal Nursery at Solliden Palace, the Swedish royal family’s private residence in Borgholm, where they spend the summer months.
Queen Camilla and Queen Silvia used watering cans to sprinkle the first drops onto the new tree once it was in the ground.

It was a rare double duty for Their Majesties. The outing came the day after King Carl XVI Gustaf celebrated his 79th birthday on April 30 with a traditional military celebration at the Royal Palace in Stockholm.
The ceremony came with a balcony appearance by his family, where baby Princess Ines made her balcony debut! King Carl XVI Gustaf and Queen Silvia, 80, became grandparents for the ninth time in February, when their son Prince Carl Philip and his wife Princess Sofia welcomed their fourth child and first daughter.

The couple named their little princess Ines Marie Lilian Silvia, with her middle names honoring both her maternal grandmother Marie and paternal grandmother the Queen.
Tree planting, ribbon cutting and plaque unveiling are staple duties of ceremonial royal roles, and both Sweden and the United Kingdom are governed by constitutional monarchies.

As King Charles looks ahead to the second anniversary of his historic coronation next week on May 6, King Carl XVI Gustaf will also mark a milestone later in the year — the 52nd anniversary of his accession on Sept. 15.
Carl Gustaf became King at age 27 in 1973 upon his grandfather’s death, as his father, Prince Gustaf Adolf, had died in a plane crash when Carl Gustaf was a baby. He is the longest-reigning monarch in Swedish history and is on track to surpass the reign of his cousin, Queen Margrethe of Denmark, who abdicated in January 2024 on the 52nd anniversary of her accession.
