The most brilliant autumn folio colors are establish among the Japanese maples ( land ) , but , alas , the blossom are insignificant and the fruits , if they are formed , are but smaller replicas of the wing fruit of the common hedge maple . Even so , there is much smasher in the leaves before they deform coloring material for they are often much - lobed , dissever into as many as eleven narrow segment , giving thesmall treeor shrub a delicate , airy appearance .
