Description: 

Sweet chestnut is a large deciduous tree, reaching up to 30m when fully grown.

Medicine:

Sweet chestnuts are a rich source of vitamins C and B and minerals including magnesium, potassium and iron. 

Known hazards:

None known.

Harvesting:

Ther’s a fantastic rick when picking the nuts out of the shells, if you stand on the encased sweet chestnuts with 2 feet and twist your feet, a bit like doing the twist, you can open up the case and easily remove the nuts without getting spiked by the spikey outside 🙂

Potential lookalikes:

Horse chestnut or conker tree (Aesculus hippocastanum) which has similar nuts, but those of the sweet chestnut are smaller and found in clusters. The leaves are completely different, with sweet chestnut having single, long, serrated leaves and horse chestnut having hand-shaped leaves with deeply divided lobes. 

Interesting facts:

The oldest known sweet chestnut tree grows on Mount Etna in Italy and is said to be around 190 feet in circumference, it is thought to be around 2000-4000 years old.
