The genus Argyranthemum includes 23 species of subshrubs native to the Canary Islands and Madeira that occur in a variety of habits. They resemble chrysanthemums and are often offered as such. The leaves are finely dissected or lobed; in some species, they are very bluish green. The daisylike flowers are borne in loose corymbs and can be single, anemone-centered, or double. Colors range from white to pink, yellow, and apricot. These plants bloom profusely from late spring to early autumn and are useful as bedding or in borders or containers.
