In the garden, Levisticum is a tall plant with dark leaves and greenish-yellow flowers. Under a microscope, however, it can morph into a cellular rainbow. This image was made using polarized light to enhance contrast. Waves in polarized light share an orientation, and special filters can block out any unpolarized waves and make the fine details easier to see.
