Can you eat conkers? And other conker facts
It’s the time of year when we all go bonkers for conkers! Get the lowdown on these super seeds.
What is a conker?
Conkers are the glossy brown seeds of the horse chestnut tree. They grow in green spiky cases and fall to the ground in autumn - the shells often split open to reveal the shiny conker inside. Look out for them in parks, streets and woods.
Can you eat conkers?
No. It's not a good idea to eat conkers because they contain a chemical called aesculin, which is poisonous. You’d have to eat an awful lot of conkers before it killed you, but you’d probably be sick.
Conkers are poisonous to most animals too, so don’t let your dog play fetch with them. Some animals, such as deer and wild boar, can eat them. But not horses, even though the tree is named after them
The best way to eat conkers is to make our yummy chocolate conkers recipe. Don’t worry – it doesn’t involve any real conkers!
Do conkers keep spiders away?
Maybe, maybe not. Sometimes people put conkers around their homes to scare off spiders, but scientists haven’t been able to prove it works. Try it yourself, what happens?
They might not keep spiders away, but there is a chemical in conkers that wards off moths. So you could also try putting some in your wardrobe to stop your woollies getting munched.
Sweet chestnuts and conkers – what’s the difference?
Sweet chestnut and horse chestnut trees aren't actually related, but their seeds are similar. Both come in greens shells, but conker cases have short, stumpy spikes all over. Inside, the conkers are round and glossy.
Sweet chestnut cases have lots of very fine spikes – so they look like little green hedgehogs! Open up the sweet chestnut and you’ll find two or three nuts inside. And unlike conkers, chestnuts are really tasty when roasted.
What can you do with conkers?
Loads of things! You can play conkers, get creative with our conker crafts, or make these kooky conker models. They're also great for helping younger children with maths -use them to make counting, sorting and weighing fun.
