Garden marguerites, also known as marguerite daisies, are cultivars of plants in the subtribe Glebionidinae of the family Asteraceae, the great majority being hybrids created in cultivation. One of the genera belonging to the subtribe, Argyranthemum, was introduced into cultivation from the Canary Islands in the 18th century, and modern cultivars are mostly sold and grown under the genus name Argyranthemum or the species name Argyranthemum frutescens, although many are actually intergeneric hybrids. The first such hybrids involved species now placed in the genus Glebionis, but other crosses within the subtribe are known. Breeding has aimed at introducing flower heads in varied colours and shapes while retaining the shrubby habit of Argyranthemum. Garden marguerites are used as summer bedding or grown in containers. Most are only half-hardy. They can be trained into shapes such as pyramids or grown as standards.
