Organisms that eat dandelions include pollinators, such as bees and butterflies, rabbits, deer and even humans. Dandelions, like many plants and flowers, have different parts that provide sustenance to different creatures. The fruit and nectar of dandelions attracts pollinators, while herbivores like rodents and deer consume the leaves.
Dandelions also produce seeds, which are popular food sources for many birds. Turkeys, goldfinches and bobwhites all eat dandelion seeds. Humans generally consume the leaves, following a tradition established by Europeans. Dandelion leaves are generally most palatable in the spring and early fall, before the leaves have fully matured. Some people eat dandelion flowers too, although the flowers have a slightly bitter taste.
