blue spruce (Picea pungens Kaibab)

So what makes Blue Spruce blue? The bluish color is due to the presence of epicuticular waxes on the needles that reflect specific wavelengths of light. More wax, more blue. this wax is produced during the needle expansion phase in spring and into early summer, but may erode due to wind and exposure to other environmental factors with age.
