Kate Middleton has returned to the RHS Chelsea Flower Show tonight after making an appearance at the Back to Nature garden she helped create for the show this morning. And this time, the Queen is with her.

Senior members of the royal family joined Queen Elizabeth II at the flower show tonight. Everyone dressed up, but the Queen was of course in the brightest outfit of all: a mint coat and floral dress. Kate wore a floral navy and black Erdem dress alongside the monarch. The Duchess of Cambridge's hair was a little Game of Thrones-esque: Kate wore a braided half-up do, similar to Daenerys' on the show. (Kate and William are self-confessed Game of Thrones fans.)

At the show, both Prince William and Kate introduced the Queen to the Back to Nature garden that Kate helped make:

Kate and the Queen have a close relationship in private. Us Weekly reported in April that Queen Elizabeth II has been helping prepare Kate for her future role as queen consort when Prince William takes the throne (likely decades down the line, after his father Prince Charles rules). “She’s really taken Kate under her wing,” a source told Us then. “The two of them will often spend hours discussing royal life and the future of the monarchy.”

The Duchess of Cambridge dressed much more casually for her morning visit to the London show. She was in a Mih Jeans white eyelet blouse with Massimo Dutti tan culottes and Superga white sneakers.

Kate was also at the garden on Sunday, where she was photographed with Prince William and their children Prince George, Princess Charlotte, and Prince Louis, who came to visit. In the Instagram caption Kensington Palace shared alongside the photos, the Palace highlighted how the garden speaks more largely to the Duchess of Cambridge's children's mental health advocacy work.

"The #RHSChelsea Back to Nature Garden, designed by The Duchess and award-winning landscape architects Andrée Davies and Adam White of Davies White Landscape Architects, is a woodland setting for families and communities to come together and connect with nature," Kensington Palace wrote on its Instagram. "Her Royal Highness is a strong advocate for the proven benefits the outdoors has on physical and mental health, and the positive impact that nature and the environment can have on childhood development in particular."

"Over the past months, Prince George, Princess Charlotte and Prince Louis have helped The Duchess gather moss, leaves and twigs to help decorate @The_RHS Back to Nature Garden. Hazel sticks collected by the family were also used to make the garden’s den. The Duchess told Monty Don in an interview for the BBC: 'I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young children. I really hope that this woodland that we have created really inspires families, kids and communities to get outside, enjoy nature and the outdoors, and spend quality time together.'"
