I've been seeing these green nut-looking objects fall from the tree in front of my house, so I cracked one open to find a walnut inside! It makes sense why I always see squirrels running around with these guys in their mouth! These walnuts are a species of deciduous tree in the walnut family, Juglandaceae, native to North America.
It is not the fruit of the walnut tree.
Non è il frutto della pianta del noce.
Juglans nigra, the eastern black walnut, a species of flowering tree in the walnut family, Juglandaceae, is native to eastern North America. It grows mostly in riparian zones, from southern Ontario, west to southeast South Dakota, south to Georgia, northern Florida and southwest to central Texas. Isolated wild trees in the upper Ottawa Valley may be an isolated native population or may have derived from planted trees.
