Aesculus hippocastanum is a species of flowering plant in the soapberry and lychee family Sapindaceae.
It is a large deciduous, synoecious tree, commonly known as horse-chestnut or conker tree.
It is widely cultivated in streets and parks throughout the temperate world,
Horse chestnuts have been particularly successful in places like the United Kingdom and New Zealand.
They are commonly found in parks, streets and avenues.
The common name “horse-chestnut” is reported as having originated from the belief that the tree was a kind of chestnut.
This is together with the observation that eating the fruit cured horses of chest complaints despite this plant being poisonous to horses. (source)
So can hamsters eat horse chestnuts?
No they can’t unfortunately. They are not good for them to eat and will make them sick if they eat them, as a result.
