variegated arum lily photo

return to gallery

Many arums are strongly variegated (their leaves have a variety of colors). The function of variegation is unknown, but may help the plant deter insect herbivores that detect plants by their color. The insect's vision may only detect the light-colored parts of the leaf which then looks eaten up and not worth trying. (Try squinting when you look at the photo and imagine eaten up leaves.)
