Kew Gardens is a famous botanic garden located in southwest London. It is home to the world's largest and most diverse collections of plants and fungi.

Kew Gardens started in 1840 from an exotic garden at Kew Park. It has over 27,000 types of living plants. Its huge herbarium (a collection of dried plants) holds more than 8.5 million preserved plant and fungus samples. The library has over 750,000 books, and there are more than 175,000 plant drawings. Kew Gardens is one of London's most popular places to visit. It is also a World Heritage Site, recognized for its special global importance.

The Royal Botanic Gardens, Kew, manages Kew Gardens and another garden called Wakehurst in Sussex. This organization is a major international research and education center for plants. It employs over 1,100 people.

The Kew site officially began in 1759. It covers 132 hectares (about 326 acres) of gardens and glasshouses. It also has many historic buildings.

History of Kew Gardens

The area where Kew Gardens is located has a long history. Royal families lived nearby since 1299. In the 16th century, courtiers built large houses in Kew. The land that became the gardens was once a large field.

The exotic garden at Kew Park was first created by Henry Capell. Later, Princess Augusta of Saxe-Gotha, the mother of King George III, expanded it. The gardens officially began when the royal estates of Richmond and Kew merged in 1772. William Chambers built several garden structures, including the tall Great Pagoda in 1761, which you can still see today.

King George III helped improve the gardens with the help of William Aiton and Sir Joseph Banks. In 1840, Kew Gardens became a national botanical garden. This happened largely because of the efforts of the Royal Horticultural Society. Under its director, William Hooker, the gardens grew to their current size of 121 hectares (about 300 acres).

The Palm House was built between 1844 and 1848. It was one of the first large buildings to use wrought iron. It is considered a very important Victorian glass and iron structure. The Temperate House, which is even bigger than the Palm House, was built later in the 19th century. It is the largest Victorian glasshouse still standing.

In 1913, the Tea House was burned down by suffragettes. In 1987, a big storm damaged many trees in the gardens.

From 1959 to 2007, Kew Gardens had Britain's tallest flagpole. It was made from a single Douglas fir tree from Canada. It was removed because of weather damage.

In July 2003, UNESCO declared Kew Gardens a World Heritage Site. This means it is a place of special cultural or natural importance to the world.

A big renovation of the Temperate House was finished in May 2018. Five trees from when the botanical gardens started in 1762 are still alive today. They are known as the 'Five Lions'.

Amazing Features at Kew Gardens

Treetop Walkway

A canopy walkway opened in 2008. It lets visitors walk 18 meters (about 59 feet) above the ground among the trees. The walkway is 200 meters (about 656 feet) long. You can go up and down using stairs or a lift. The walkway is made of metal and sways a little in the wind. It was designed to look like trees as it rusts.

It connects the art galleries to other houses and gardens.

The Hive

The Hive opened in 2016. It is a special experience that shows you the amazing life of bees. It is 17 meters (56 feet) tall and looks like a giant honeycomb. The Hive is made of thousands of aluminum pieces. It was so popular that it became a permanent part of Kew Gardens.

The Kew Explorer is a road train that takes visitors on a tour around the gardens. It uses clean fuel to reduce pollution. The driver provides interesting information, and there are several stops where you can get off and explore.

Giant Compost Heap

Kew Gardens has one of the largest compost heaps in Europe. It is made from garden waste and manure. This compost is used to help the plants in the gardens grow. There is a special viewing platform where visitors can see the compost heap.

Guided Walks

Volunteers lead daily tours of the gardens. They share interesting facts and stories about the plants and history of Kew.

Plant Houses at Kew

Alpine House

The Davies Alpine House opened in 2006. It is designed to keep alpine plants cool. These are plants that grow high up in mountains or near the poles. The roof is 10 meters (33 feet) high to allow natural airflow. It has automatic blinds to prevent overheating and a system that blows cool air over the plants. The glass is special and lets in a lot of sunlight. To save energy, the air is cooled by pipes buried underground.

Kew has over 7,000 alpine plants. Only about 200 are displayed at a time, and they are rotated regularly.

Great Pagoda

The Pagoda

In the southeast part of Kew Gardens is the Great Pagoda. It was built in 1762 by Sir William Chambers and looks like a Chinese Ta. It has ten octagonal (eight-sided) stories. From the bottom to the top, it is 50 meters (164 feet) tall.

Each story has a roof that sticks out, like Chinese buildings. Originally, these roofs had large dragons on them. People used to say the dragons were made of gold and sold by King George IV to pay his debts. But actually, they were wooden and painted gold, and they rotted away over time. The Pagoda was closed for many years but reopened in 2006. It was fully restored in 2018, and 80 new dragons were made for it.

The palace was restored and reopened to the public in 2006. In front of the palace is a sundial given to Kew Gardens in 1959.
