The family is cosmopolitan (not found only in Antarctica), and its representatives inhabit a variety of habitats. Despite the great diversity, a relatively small number of representatives of the Asteraceae are of utilitarian importance, in addition to species grown as ornamental plants.

Edible representatives of the Asteraceae include the wild sunflower (topinambur), lettuce, chicory, and artichoke.
