The King has reportedly had the love of gardening from a young age, with the 74-year-old previously telling Gardeners World that he and Princess Anne “grew vegetables and things” at Buckingham Palace as children.

Charles previously recalled his time at Royal Lodge with his grandmother, the Queen Mother, who he shared a close bond with.

The King said: “I remember being absolutely riveted as a child wandering about, looking at all the plants.”

The King also said that he “grew to love trees”, adding that the “smell and everything had a profound effect on me”.

Due to the family-of-four living in the US, the King hasn’t spent much time with his two youngest grandchildren.

Last year, a royal source claimed that Charles had an “emotional” first meeting with his granddaughter, Lilibet.

It was reported that the King got to meet his youngest grandchild during Meghan and Harry’s visit for the late Queen’s Platinum Jubilee.

The source added that it was also “very, very special” for the King to be reunited with three-year-old Archie.

They added the fact he got to finally meet his granddaughter, who turn one during the visit, was a “very, very wonderful thing”.

Earlier this month, the Duke and Duchess of Sussex confirmed that the two children will formally use their Prince and Princess royal titles.

Archie and Lilibet had not used them from birth, with them being added as ‘Master’ and ‘Miss’ on the official royal line of succession.

A spokesperson for the couple released a statement stating that ‘Princess Lilibet Diana’ had been christened in the US on March 3.

The following day, Meghan and Harry defended their decision to allow their children the use of their royal titles.

Following some backlash, particularly due to Harry’s continuous comments about his time as a royal, the couple claimed that it is their children’s “birthright” as grandchildren of the monarch.
