She helped plant "Catherine's Rose" -- a new bloom named in her honor -- as part of a nationwide effort to support healing gardens across the U.K.
Kate Middleton returned to public duties with a meaningful visit to a hospital garden, where she spoke candidly about the challenges of her cancer journey, even after treatment ended.
The Princess of Wales, 43, traveled to Colchester Hospital in Essex on July 2 to spend time in a specially designed well-being garden that offers a restorative space for patients, NHS staff and visitors.
She said, "You put on a sort of brave face, stoicism through treatment, treatments done, then it's like, 'I can crack on, get back to normal,' but actually the phase afterwards is really, really difficult.'"
Princess Kate's outing came after she was said to be disappointed not to join Prince William at Royal Ascot on June 18. Those close to her emphasized that she is still working to find the right balance while easing back into official duties following her cancer treatment.
While she hadn't made a public appearance since, Kate and William quietly hosted a private meeting with Melinda French Gates at Windsor Castle on June 25 -- not far from their home at Adelaide Cottage, where they live with their three children, Prince George, 11, Princess Charlotte, 10, and Prince Louis, 7.
During her hospital visit, she helped plant several "Catherine's Rose" plants -- a newly launched bloom named in her honor by the Royal Horticultural Society -- alongside staff who volunteer in the garden.
The pink roses, with proceeds benefiting the Royal Marsden Cancer Charity, where Kate received care during her own cancer treatment, were donated as part of a wider effort to bring healing green spaces to those in need. Fifty of the plants were delivered to Colchester Hospital this week, and 500 will be distributed to wellbeing and community gardens across the U.K. this summer -- including Maggie's centers for cancer patients, East Anglia's Children's Hospices (a longtime cause of Kate's) and Horatio's Gardens, which support people living with spinal injuries.
Tuesday's appearance marks another step in Kate's gradual return to the spotlight, following her announcement in March 2024 that she had been diagnosed with cancer and was undergoing chemotherapy. Although she shared in January that she's now in remission, the princess continues to manage her schedule carefully.
At Colchester, Kate spent time with award-winning garden designer Adam Frost, who worked with NHS staff to shape the space to meet the needs of the hospital community. The hospital's well-being garden, which opened in July 2024, was created in partnership with the RHS, Colchester & Ipswich Hospitals Charity and NHS Charities Together -- the latter of which is a joint patronage of Kate and Prince William.
Kate has long championed the power of nature to support emotional, physical and spiritual well-being. And those close to her say that spending time outdoors was a vital part of her own healing journey.
"She would say, 'During my recovery, I spent a lot of time in the outdoors because that's where I felt at peace,'" said Dwayne Fields, a chief scout who joined Kate on a recent outing in the Lake District. "When people speak about themselves, it feels like they are giving you something ... That's her superpower. She's a wonderfully warm person and invites you into a conversation."
Kate also visited the hospital's Cancer Wellbeing Centre to meet with patients and staff and hear how gardens like the one at Colchester are playing a bigger role in healthcare settings. The RHS plans to include the garden in research for its upcoming Blueprint for Wellbeing Gardens, which will launch in spring 2026.
The princess, who has supported nature-forward initiatives from forest schools to therapeutic gardens, once described nature as "hugely beneficial to our physical and mental well-being." In 2019, she shared her enthusiasm for "forest bathing," a Japanese practice that promotes mindfulness through immersion in the natural world.
Reflecting on the poignant image of Kate photographed beneath a tree in Windsor in the summer of 2024, royal biographer Sally Bedell Smith told PEOPLE, "There she is in nature, which has fortified her, and looking upward in a sign of real hope and encouragement for everybody."
