Kate Middleton and Prince William are supporting a new gardening therapy project at a rehab center.

They are partnering with Annabelle Padwick and her Life at No.27 initiative to fund and build the gardens.

The royal couple is interested in people's stories and experiences and wants to make a difference in their lives.

Mental health and gardening/horticulture are important causes for the couple and this project combines the two.

The project will offer another therapy option for clients at the South Wales center and the community.

The royal couple's involvement has rallied other organizations to help with the project.

The couple's visit showed interest and support, making the residents and their families feel valued.

Prince William and Kate also competed in a spin bike contest and took selfies with well-wishers during their visit.

Prince William was also unveiled as the new patron of the Wales Air Ambulance charity.
