Palm House and Rose Garden

The elegant exterior and steamy interior of Kew's Palm House have long made it iconic of Kew.
The Palm House at Kew

History and design

Experts consider Kew’s Palm House to be the most important surviving Victorian iron and glass structure in the world. It was designed by Decimus Burton and engineered by Richard Tanner to accommodate the exotic palms being collected and introduced to Europe in early Victorian times. This pioneering project was the first time engineers used wrought iron to span such large widths without supporting columns. This technique was borrowed from the shipbuilding industry and from a distance the glasshouse resembles an upturned hull. The result is a vast, light, lofty space that can easily accommodate the crowns of large palms, while boasting 16,000 panes of glass.

Heating was an important element of the glasshouse’s design, as tropical palms need a warm, moist environment to thrive. Originally, basement boilers sent heat into the glasshouse via water pipes running beneath iron gratings in the floor. A tunnel ran between the Palm House and the Italianate Campanile smoke stack that stands beside Victoria Gate. This 150-metres long (490ft) passage served the dual purpose of carrying away sooty fumes to be released from the chimney and enabling coal to be brought to the boilers by underground railway.Today, the glasshouse is heated using gas, and the tunnel houses the Palm House Keeper’s office. Originally, palms, cycads and climbers were planted in large teak tubs or clay pots that sat atop benches above the iron gratings. However, in 1860, two large central beds were dug and the tallest palms planted in them. Subsequently, most of the glasshouse’s plants were dug into beds to form a miniature indoor tropical rainforest.

Today, the tallest palms that need the most room are located beneath the central dome. These include the peach palm (Bactris gasipaes), babassu (Attalea speciosa), queen palm (Syagrus romanzoffiana) and the coconut palm (Cocos nucifera).

Conservation and restoration

The Palm House was first restored between 1955 and 1957 when its glazing bars were cleaned and the entire house re-glazed. At that time, the boilers were converted to oil and moved close to the Italianate Campanile. Between 1984 and 1988, a more comprehensive overhaul was undertaken. The Palm House was emptied for the first time in its history, with most plants moved to other glasshouses. Those that were too large were cut down and used to make specimens for the Herbarium and Museum. Under direction of the Property Services Agency, this Grade I listed building was completely dismantled, restored and rebuilt. Ten miles of replica glazing bars made of stainless steel were put in place to hold new panes of toughened safety glass. The restoration took as long to finish as the glasshouse took to build. 


Inside the Palm House

Things to look out for

Highlights in the South Wing, which contains plants from Africa and the Indian Ocean islands, include the African oil palm (Elaeis guineensis) — the most important oil-producing plantation palm in the Tropics — and the rare triangle palm (Dypsis decaryi) from Madagascar.

The main central section houses plants from the Americas, including many economically-important species. You’ll find cocoa, rubber, banana and papaya plants growing here alongside the Mexican yam (Dioscorea composita), which was used to develop the contraceptive pill.

The North Wing showcases plants from Asia, Australasia and the Pacific, the region that contains the world’s greatest diversity of palms. Here you’ll find climbing palms called rattans, from which cane furniture is made. Also, there are several Asian fruit trees including mango, starfruit, breadfruit and jackfruit.

Marine Aquarium

Housed, in the basement of the Palm House, the Marine Aquarium recreates four major marine habitats, emphasising the importance of marine plants.


Rose Garden

Roses in the Rose Garden

The Rose Garden stands in a historically important part of Kew where, in 1845, landscape designer William Andrews Nesfield laid out his Palm House parterres. 

To celebrate its 250th anniversary, Kew replanted the historic Rose Garden that sits behind the Palm House, inspired by the original designs of William Nesfield.

The sunken areas on the western side of the Palm House, along with the semi-circular holly hedge, are remnants of Nesfield's intricate design of beds and walkways. He originally planted the area with evergreens, including yews, euonymus and golden holly. The area was converted to a rose garden and planted with 6,000 roses in 113 beds in 1923. 

Did you know:

  • During WWII, when Britain was unable to obtain citrus fruits, Kew helped identify species, varieties and hybrids of native British roses that contained vitamin C. The hips richest in vitamin C were those produced by roses in northern England and Scotland. Between 1941 and 1945, volunteers harvested nearly 2,000 tonnes of hips. These gave rise to some 10 million bottles of National Rose-hip Syrup. 
  • In 2009, a new specially-bred rose was named Rosa ‘Kew Gardens’ in celebration of the Gardens' 250th anniversary. The Queen was presented with one of the roses, a thornless white-flowered English musk hybrid, when she visited the Gardens in May to celebrate the anniversary.
