The Caley Brothers was founded by sisters Lorraine and Jodie after discovering a passion for mushroom cultivation. After selling their mushroom-growing kits at farmers markets they were soon discovered by TV personality Arit Anderson and invited to contribute to her RHS Show Garden. They were also part of the Gold-winning 'Planet Studio' display at RHS Chelsea 2022. In 2023, they returned with their debut solo display of edible mushrooms, a first for RHS Chelsea, winning Gold and the New Design Award. They also host workshops, speak on podcasts and give talks at major gardening events, such as RHS Hampton Court and Gardeners' World Live.

The Royal Botanic Gardens, Kew, has cultivated plants for more than 250 years. Today, Kew’s horticulturists grow over 19,000 species of plants in the gardens – the most diverse collection in the world.
