Tree of the Month: Horse Chestnut
You'll often see me growing in your parks. I am often standing on my own, majestically reaching a height of 100 feet and I could live to be 200 years or more. That's pretty impressive even though I say it myself.
You can't miss me in the summer because I have hundreds of large white or pink pyramid shaped flower heads. In fact, people say they look like candles, so I suppose you could say that I'm a giant living candelabra.
I am not a native to Britain but most people think I am. For hundreds of years it was thought that the Romans introduced me to your country. Well, let's put that 'old chestnut' to rest. There's no evidence that is true but they did introduce my cousin, the sweet chestnut, to your shores. Recently discovered written records state that my ancestors were brought to Britain from Turkey in the C16th. They were planted in parks so I suppose, in a way, they were early migrants to your country.
During late summer you will notice large green spiky ball-like objects hanging from our branches. They protect the conker seeds hidden inside from being eaten by squirrels and other animals. I always think they look like the spiked metal balls attached to chains used as weapons by knights in Norman times.
Children call my large roundish seeds of shiny reddish-brown, conkers and they know me as the conker tree. However, do you know why the grown ups gave me my true name of horse chestnut? Well, there are two reasons. Firstly, they used to crush up my seeds and mix them in to horses' food if it had a cough, so it was a type of medicine. However, don't try this at home if you have a cough. My seeds contain a toxin, which is not strong enough to harm a horse but it could make you very sick.
The second reason is that if you break off one of my leaf stalks from its branch you will see a horseshoe shape scar left on the branch. It will even have what look like nail holes.
