In January 2019, it was confirmed that the Duchess would work together with the Royal Horticultural Society as one of the co-designers for a garden display at the 2019 Chelsea Flower Show. Catherine designed the "Back to Nature Garden" together with Andree Davies and Adam White. The garden, which featured "a tree house, waterfall, rustic den and a campfire" among other parts, was unveiled at the Chelsea Flower Show in May 2019 to emphasise "the benefits the natural world brings to mental and physical well-being". The garden was later expanded and moved to Hampton Court Palace as a part of the Hampton Court Palace Flower Show. In May 2019, as a part of their "Heads Together" initiative, the Duchess of Cambridge together with her husband and in-laws, launched Shout, a text messaging service for those who suffer from mental issues. In October 2019, the Duchess of Cambridge, together with other members of the royal family, voiced a PSA video for Public Health England "as part of its Every Mind Matters program". In late March 2020, the Duke and Duchess of Cambridge started supporting a new mental health initiative by the Public Health England amidst the COVID-19 pandemic in the United Kingdom.
