The Royal Family’s love of gardening and the outdoors will bring a big change to one of their favourite homes in 2026. For the first time, Sandringham House in Norfolk will host a special garden show organised by one of the most famous organisations in the country.
In July 2026, the RHS will add the royal residence to its growing list of ever popular garden shows. The event at Sandringham runs from July 22 and is sure to attract royal attention.
The King and Queen are regulars at the Chelsea Flower Show, held in May every year, and Charles III has a major role within the RHS that was cemented with a special gift last year.
King Charles has received a green gift that most gardeners can only dream of- the Royal Horticultural Society has presented The King with a new Royal Signature.
The RHS announced in 2024 that King Charles would be the new Royal Patron, following his late mother. A lifetime gardener, His Majesty was a more than appropriate fit for the role.
In July 2025, the RHS shared a new Royal Signature created for the King; a Royal Signature is a botanical painting created for a specific event or moment.
Botanical artist Gillian Barlow and calligrapher Timothy Noad MBE collaborated on the new painting celebrating The King’s new role.
The piece of art is based on Charles’ new gardens at Sandringham. It has a rich colour palette of gold, bright pink, coral, crimson, purple, and mauve. It also includes some of The King’s favourite plants, including Geranium sanguineum, Magnolia campbellii, Narcissus ‘Jetfire’, and crocus.
The painting is amongst a strong group of over 40 paintings, with the first Royal Signature created in 1816 for Queen Charlotte. It will be displayed to the public in 2026 at the first ever RHS Flower Show at the Sandringham Estate.
RHS General Director Clare Matterson shared, “We are incredibly honoured that His Majesty The King is our charity’s Patron. This painting marks over 200 years of Royal patronage and is testament to the Royal Family’s true love of gardening and its enduring relationship with the RHS.”
