Kew Gardens

The Royal Botanic Gardens at Kew in Richmond, southwest London, cover 300 acres of landscaped grounds and glasshouses and hold the world's largest collection of living plants, comprising over 50,000 species from every continent. Designated a UNESCO World Heritage Site in 2003, Kew has operated as a scientific institution since the 18th century and continues active research into plant conservation, with living specimens and a 7-million-specimen herbarium supporting work on biodiversity and food security. Visitors arriving at the Victoria Gate on Kew Road enter a garden that functions at multiple scales: formal rose gardens and geometric flower beds give way to ancient specimen trees, a bamboo garden, the Woodland Garden in spring bluebell season, and a Treetop Walkway at 18 metres above the woodland floor. The Palm House, built between 1844 and 1848 by Decimus Burton and Richard Turner, is the most iconic structure in the gardens — a soaring curved glass-and-iron greenhouse maintaining tropical rainforest temperatures and housing palms, rubber trees, and rare cycads that predate the dinosaurs. The Temperate House, reopened after restoration in 2018, is the world's largest Victorian glasshouse at 4,880 square metres and holds the world's largest indoor plant: a Chilean wine palm planted in 1846 now standing nearly 17 metres tall inside the structure. The Princess of Wales Conservatory contains ten climate zones in a single building, from dry desert to humid mangrove. The Waterlily House displays the giant Victoria amazonica lily pads, which can support the weight of a child. Seasonal highlights include cherry blossom (late March to mid-April), bluebell woods (April to May), rhododendrons (May to June), and the summer fireworks season when the gardens open late on Friday evenings.
