Horse Chestnut

These are horse chestnut trees, currently dropping a lot of fruit. They look similar to chestnuts, but are toxic and can cause vomiting, diarrhea, and even respiratory distress if ingested, so never eat them. The fruit of the horse chestnut is also called 'marronnier' in other words. If the fruit's husk is smooth, it's a horse chestnut (Japanese marronnier), and if the husk has hairs, it's a European horse chestnut (European marronnier). They look like chestnuts, but never eat them~
