Hi Steve & All, Oct 17, 2007 Milky leaf sap is a quick way to distinguish Norway Maple from look-alikes. During the growing season, a Norway Maple leaf petiole base will 'bleed' copious milky sap if the leaf is bent back so that the petiole breaks away from the stem at the abscission layer. I just checked our leaves and about 1/3 of them will still bleed faintly; as white dots (that can be brushed away) where the vascular bundles are.
