Sweet chestnut trees live to an age of 500 to 600 years. In cultivation they may even grow as old as 1000 years or more. Their large genetic diversity and different cultivars are exploited for uses such as flour, boiling, roasting, drying, sweets or wood (Wikipedia).
Oh, this brings back memories. every fall we walk in the woods and I find the chestnuts. Take them home and eat them. I always love the raw fresh ones we picked.
