Chelsea Flower Show
A five-day May horticultural festival held in London by the Royal Horticultural Society
The Chelsea Flower Show is an annual five-day garden exhibition held every May in London by the Royal Horticultural Society. Landscape designers, plant nurseries and visitors gather to view show gardens, rare blooms and floral artistry.
When is Chelsea Flower Show kept?
Chelsea Flower Show is kept every year in May for five days.
The Chelsea Flower Show is Britain's premier horticultural gathering, held across five days every May in London. Organised by the Royal Horticultural Society, the event brings together plant breeders, landscape architects and garden enthusiasts. It serves as a stage for innovative garden design, the unveiling of newly bred flowers, and a traditional social fixture marked by royal attendance.
Show gardens and botanical tents
At the centre of the show is the large Floral Marquee, filled with exhibits from professional nurseries, plant merchants and hobbyists. Surrounding this pavilion are outdoor show gardens created by prominent designers, alongside smaller plots known as Artisan and Urban Gardens. Displays range from full-scale architectural landscapes to arrangements of vegetables, ornamental trees, floristry and educational botanical exhibits. The layout allows visitors to walk through varied planting styles, examine rare specimens and observe emerging trends in garden design.
Origins and moves across London
The Royal Horticultural Society staged early flower shows in Chiswick beginning in 1833, before establishing the Great Spring Show at Kensington in 1862. To improve transport access and reach central London, the society shifted the event to Temple Gardens in 1888. A large one-off exhibition took place at the Chelsea Hospital site in 1912, leading the organisation to relocate the spring show there permanently the following year. Aside from pauses during both world wars and a brief delay during the 1926 General Strike, the show has run at the same venue ever since.
Royal attendance and public gatherings
Monarchs and members of the British royal family have maintained close ties with the exhibition for over a century. Royal previews became a custom in the early twentieth century, accompanied by traditional Chelsea tea parties launched during the 1920s. The show has also reflected national milestones, hosting special Empire floral displays for the coronation of George VI in 1937 and commemorative gardens for Queen Elizabeth II and King Charles III. In recent years, youth events such as school gardening picnics have added new elements to the gathering.
Medals and cultivar launches
Competition forms an essential part of the event. Judging panels assess entries across distinct sections, including the Flora division for gardens, Hogg for forestry, Knightian for edible crops, Lindley for scientific interest, and Grenfell for floral artwork. Outstanding exhibits receive gold, silver-gilt, silver or bronze grading, while premier designs compete for the Best Show Garden trophy. Growers frequently use the show to debut newly cultivated flower varieties, reviving interest in older species or introducing novel plants to the gardening world.
How Chelsea Flower Show is kept
The event opens with a royal preview before welcoming society members during the first two days, followed by public ticket holders for the remainder of the week. Visitors follow pathways across the site to inspect designer gardens, specialist trade stands and the main marquee of botanical displays. Juries assess every category to award bronze, silver, silver-gilt and gold honours, while nurseries debut new plant cultivars and attendees take afternoon tea.
When and where
The festival takes place annually across five days in late May. The first two days are reserved exclusively for members of the Royal Horticultural Society, after which general ticket holders may attend.
The event is staged across an eleven-acre riverside park at the Royal Hospital in Chelsea, located within the Royal Borough of Kensington and Chelsea in London.
What Chelsea Flower Show means
The gathering represents the height of the British gardening calendar, celebrating spring growth, landscape design and plant breeding. It unites recreational gardeners with professional botanists and nursery growers, serving as both a showcase for creative horticultural innovation and an enduring civic tradition connected with British public life.
