Castanea sativa Fr: Châtaignier
The châtaignier can also grow to 30 m, but has a taller trunk and lacks the thick, rounded shape of the horse chestnut. The 400-year-old châtaigniers in the photo was taken in March, in the Maures.
The sweet chestnut is grown for its fruit, which looks similar to the horse chestnut, but has a flattened side and has the advantage of being edible. In France, street vendors sell roasted chestnuts, called marrons. These marrons are actually the châtaignes from the châtaigner, not the nuts from the marronnier.
