Kew Gardens, home to the world’s largest plant collection, has announced plans to remove select trees from its iconic Palm House glasshouse to enable a comprehensive renovation effort. The Victorian-era structure, which comprises 16,000 panes of glass and ornate ironwork, has deteriorated significantly, with rust and warping making it increasingly difficult to maintain the hot, humid climate required by the facility’s rare botanical specimens.
The renovation project, scheduled to commence in 2027 subject to fundraising success, will necessitate the relocation or removal of approximately 1,000 plants. Many specimens cannot be transported due to their size, particularly the giant palm trees that extend to the greenhouse’s roof. Kew’s staff have already begun relocating plants to a behind-the-scenes tropical nursery, where specimens can acclimate to new conditions before eventual reintroduction to the renovated space. The Palm House will remain accessible to visitors until full renovation work begins.
The project has created unexpected conservation opportunities for Kew’s scientists. During efforts to address the imminent felling of the Ravenea Moorei—a species native to the Comoros islands that was believed to exist only as a single male specimen at Kew—researchers conducted an expedition and discovered a wild population. This discovery enabled successful propagation of the species, with ten young plants now growing in the tropical nursery. Additionally, seeds from the spike-covered Aiphanes eggersii have been successfully sown for the first time.
Specialist conservators have been engaged to relocate delicate specimens, including the Eastern Cape giant cycad, which has occupied Kew since 1775 and remains the world’s oldest potted plant. Scientists are actively propagating numerous endangered species, including the Ramosmania rodriguesii, which exists as a single surviving tree in the wild. Young specimens cultivated at Kew have already been reintroduced to natural habitats.
Kew will launch a fundraising campaign this October to finance the “Save London’s Rainforest” initiative. Officials anticipate the renovation will span approximately 50 years, during which the propagated plants and young specimens will mature within the restored greenhouse.
