Baccharis /ˈbækərɪs/ is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", however true groundsels are found in the genus Senecio.
Baccharis, with over 500 species, is the largest genus in the Compositae. It is found throughout the Americas, distributed mainly in the warmer regions of Brazil, Argentina, Colombia, Chile and Mexico, with B. halimifolia ranging northward along the Atlantic Coast to the southern tip of Nova Scotia in Canada.
If present, the leaves of Baccharis are borne along the stems in alternate fashion. Flowers are usually white or pinkish. There are no ray flowers, but many disk flowers which are either staminate or pistillate.
