Olive ash is used to describe the heart wood when, more so in older trees, it turns an olive brown color. Only had it once and the bowls would fly off my shelves at the shows! I am not sure if that is olive ash or not. the grain just doesn't look right to me. Maybe because our western ash has different growth rings and the eastern stuff grows more slowly. I had some butternut once. It was green, and smelled like vinegar. The branch growth rings were scalloped, which I heard was typical for butternut. Made for a very nice spider web pattern in the bowls.
