The Big Flower Fight is a reality competition show where ten pairs of florists, sculptors, and garden designers compete to create larger-than-life flower installations. Each week, the contestants are given a different theme and must use their creativity and skills to bring their vision to life. The teams face challenges such as creating giant insects out of flowers, designing floral fashion, and constructing massive floral structures. The judges critique the creations and eliminate one team each week until only one pair is left standing. The winning team receives the title of "Best in Bloom" and a chance to showcase their work at the Royal Botanic Gardens, Kew.
