Yes, in Poland, there are edible chestnuts known as sweet chestnuts (Castanea sativa). This species was introduced to Poland and other parts of Europe as a cultivated tree. The sweet chestnut tree is grown for its edible nuts, known as sweet chestnuts.
Trees bearing the fruits of the edible chestnut are often found in parks, gardens, and urban areas. Sweet chestnuts are consumed after proper preparation, such as boiling, baking, or roasting. Remember to distinguish the sweet chestnut tree from other chestnut species, such as the horse chestnut (Aesculus hippocastanum), whose seeds are toxic and not suitable for consumption.
