Kew Gardens
Kew Gardens holds more than 2.4 billion seeds from 189 countries, most of them never discussed in any travel guide
The Millennium Seed Bank at Kew’s Wakehurst outstation in West Sussex is the largest wild plant seed bank in the world, containing roughly 16 percent of all wild plant species on Earth. It exists because Kew’s scientists calculate that a significant portion of those species face extinction within decades, and frozen seeds may eventually be all that survives. This fact sits alongside the more comfortable story that Kew tells about itself as a paradise of glasshouses and afternoon tea, and both are true simultaneously. The gardens opened in 1759 under Augusta, Dowager Princess of Wales, became scientifically famous under Joseph Banks from 1772, and received UNESCO World Heritage status in 2003. They cover 121 hectares in southwest London, hold 28,680 taxa of living plants, and attract over 2 million visitors a year.
The part of Kew’s history that most tourist literature skips is its colonial role. Under director Joseph Hooker in the 19th century, Kew operated as a global clearing house for economically valuable plants. Colonial gardens were required to ship specimens back to Kew, where scientists would acclimatize them before redistributing them to other colonies as profitable crops. The most documented example is rubber. In 1876 the explorer Henry Wickham smuggled 70,000 rubber tree seeds out of the Brazilian Amazon, presenting them at customs as botanical curiosities for the Queen. Hooker paid him £700 and germinated the seeds at Kew before shipping seedlings to Ceylon (Sri Lanka) and Malaya. Within decades, British-controlled plantations had broken the Brazilian monopoly on rubber entirely. The Palm House that visitors now admire contains direct descendants of plants obtained by similarly aggressive means.
Getting there
Kew Gardens station on the District Line (Richmond branch) is a 500-metre walk to Victoria Gate, the nearest entrance. From central London, the journey on the District Line takes around 30 to 40 minutes depending on your starting point; South Kensington is about 20 minutes, Victoria around 30 minutes. The station is in Zone 3, so a standard Oyster or contactless fare applies.
Ticket prices in 2026
Peak season (1 February to 31 October): £20 online on weekdays, £22 on weekends and bank holidays. Off-peak season (1 November to 31 January): £12 on weekdays, £14 on weekends and bank holidays. Children under 4 enter free. From 25 June to 1 September 2026, the UK government’s Great British Summer Savings scheme is reducing prices temporarily. The London Pass includes Kew Gardens admission and is worth calculating against if you are also visiting several other London attractions in a short window.
Book online in advance. The main gates can queue for 20 minutes on busy spring weekends when cherry blossom and tulip seasons coincide.
What to see
The Palm House is the obvious first stop, a Victorian iron-and-glass structure from 1848 containing palms and tropical plants including direct rubber-tree descendants. The Temperate House is the world’s largest surviving Victorian glasshouse and reopened after a five-year restoration in 2018. It repays a slower visit than most people give it.
The Treetop Walkway at 18 metres above the forest floor offers views across the canopy that most visitors do not associate with London. It is quiet early in the day and crowded by mid-afternoon. Kew Palace, tucked in the northwestern section of the gardens, is the smallest royal palace in Britain and a genuinely atmospheric building that most visitors walk past quickly. It served as a retreat for George III during his periods of mental illness and still contains some of the original furnishings.
The Hive, a large sculptural installation in the gardens that represents the interior structure of a beehive, uses LED lights and audio that respond to real data collected from a Kew beehive. It is one of the few outdoor installations of its type that holds up on repeated visits.
A new learning centre is under construction from spring 2025 and is scheduled to open in the second half of 2026.
Where to eat inside the gardens
The Orangery is the largest on-site cafe, open throughout the day with lunch options and afternoon tea. It is the obvious choice for the volume it can handle. The White Peaks Cafe near the Temperate House is smaller and less crowded on busy days. If you want to eat without paying restaurant prices, the gardens allow picnics and most visitors who stay for a full day bring food.
Where to stay nearby
Kew itself is a quiet residential neighbourhood with limited hotel stock. Richmond, a five-minute District Line ride away, has a much wider range. The Richmond Hill Hotel has direct views over the Thames and Richmond Park and runs at £150 to £250 per night depending on season. For budget accommodation, Twickenham and Kew Bridge both have options within a 20-minute walk. Most visitors treat Kew Gardens as a day trip from central London, which works well if you arrive by 10am and leave after 4pm.
Practical timing
Kew opens at 10am daily, with last entry one hour before closing. Spring (March to May) is when the gardens are most visited and most spectacular, particularly the Cherry Walk, the bluebells in Queen Charlotte’s Cottage grounds, and the tulip display. Summer brings the Chihuly glass sculptures (when scheduled) and outdoor events including concerts. Autumn turns the Arboretum to considerable effect, with some specimens over 200 years old changing color in sequence over several weeks. Early November through January is the least-visited and least-expensive period.
The Great Pagoda, a 10-storey 18th-century Chinese-style tower that was closed for 40 years, is currently open after a recent restoration. Check availability before visiting as it closes on days of extreme heat due to temperature safety concerns.
