Two sorts of walnut

As well as the English walnut, we also have some near-native, Black walnut trees around the creek. I thought they were a type of sumac until this morning, trying to cut one of the fruits open and failing badly.

The English walnut is grafted, about a foot above the ground, probably to a black walnut rootstock. It may be impossible to crack the pure black walnut fruits!
