The brainchild of BBC Southern Counties Radio, this garden has been created as a fun representation of a rainbow, designed to appeal especially to families. After the show, the key elements of the garden are being transferred to the grounds of Rainbow Trust Children’s Charity respite home in Leatherhead, Surrey.

Drawing on the bright colours of Rainbow Trust’s logo, the garden features a cheerful arc of colour, showcasing a range of traditional and newer bedding plants. Using the rainbow as a symbol of hope, the planting is designed to stimulate the senses and to be particularly attractive to children. The eye-catching colour-themed design includes herbaceous plants and shrubs. The progression of colours develops from red to deep violet, and the transition from day to night is marked with individual white flowers that appear like stars in the dark sky. A green path meanders through the rainbow, representing our journey through life. When upturned, the rainbow becomes a vibrant smile, with the sun shining brightly at one end.
