Kew has trees that are ancient, fascinating or historic — and often all three at once. Here's some of our favourite trees, for visitors to enjoy below.
As one of Europe's largest native trees, the ash is steeped in mythology and superstition. It was believed that passing a sick child through a large split in the tree's trunk would cure it, and burning logs of ash were thought to drive evil spirits away.
Huge beech forests growing in the Chilterns led to a thriving furniture industry there. In 1887, a group of sporty furniture makers founded Wycombe Wanderers Football Club. To this day, the team's nickname is The Chairboys.
In medieval times it was bad luck to take sprigs of hawthorn blossom indoors as it foretold a death in the household. We now know that chemicals in the scent of the hawthorn are present in decaying corpses, perhaps the reason for this myth.
The original maze at Hampton Court was probably formed of hornbeam hedges before being replaced with yew and holly. Hornbeam does make a good hedge, as it is easy to maintain, with dense foliage, some of which is retained over winter, albeit dead.
Juniper berries are famously used to flavour gin. In fact, the word 'gin' comes from the French word for both the drink and the berry itself - genièvre.
One of Britain's most popular flowering trees, the common laburnum is also among the most poisonous. Just 15 - 20 of the pea-like seeds could be a lethal dose. Luckily the most popular hybrids rarely produce viable seed.
Kew botanist R. A. Salisbury brought this conifer to Kew as a six-inch seedling from the South of France in 1814.
Housed in a large wooden box at the southern end of the Palm House, the Eastern Cape giant cycad could be the oldest pot plant in the world.
This tree is one of Kew's five remaining 'Old Lions' - trees planted in 1762 as part of the original Gardens - and is now supported by metal bands.
Deer and squirrels eat Indian horse chestnut seeds, but they can be poisonous to humans. The small conkers contain a substance called aesculin, which destroys red blood cells.
