Argyranthemum–commonly called Marguerite daisy–is a subtropical evergreen subshrub that is grown for its display of prolific daisy-like flowers. Argyranthemum is sometimes confused with and sold as chrysanthemums.
Argyranthemum bears loose corymbs of daisy-like single, sometimes anemone-centered or double flowerheads in white, rose-pink, yellow, or apricot. Plants grow from 18 to 36 inches (45-90cm) tall and wide and are nearly completely covered with blossoms when in bloom. The leaves are entire to finely dissected or lobed; they vary from green to glaucous.
Argyranthemum can be grown in beds and borders in frost-free regions. They grow best in moderately fertile, well-drained soil in full sun.
Argyranthemum is a genus of 23 species of spreading to erect evergreen subshrubs native from the Canary Islands to Madeira.
