Features and characters of the individual

This tree is one of the tallest in the Botanical Garden. And with good reason, this black walnut belongs to a species with straight and slender trunks. Its dark bark and distinctive fruits at the base of the tree mark its presence to visitors. Here in the lower and more wooded part of the park, it is likely to reach a height of 40 m one day. And it probably still has a good century ahead of it! The hardwood from this species is not frequently made into furniture or rifle butts, as it is in its American counterparts.
