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 Asteraceae. 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.

Some species of Baccharis are toxic to animals; in particular, consumption of B. coridifolia may lead to necrosis in the gastrointestinal tract of cattle, horses, sheep, and rabbits.

The genus Baccharis is named after Bacchus (Dionysus), the Roman god of wine.

Baccharis is related to the genera Archibaccharis and Heterothalamus. All baccharis are dioecious except Baccharis monoica.

Baccharis halimifolia is a North American species of shrubs in the family Asteraceae. It is native to Nova Scotia, the eastern and southern United States (from Massachusetts south to Florida and west to Texas and Oklahoma), eastern Mexico (Nuevo León, San Luis Potosí, Tamaulipas, Veracruz, Quintana Roo), the Bahamas, and Cuba.

Widely used common names include eastern baccharis, groundsel bush, sea myrtle, and saltbush, with consumption weed, cotton-seed tree, groundsel tree, menguilié, and silverling also used more locally. In most of its range, where no other species of the genus occur, this plant is often simply called baccharis.

Baccharis halimifolia is a fall-flowering shrub growing to about 12 ft (4 m) high and comparably wide, or occasionally a small tree. Its simple, alternate, thick, egg-shaped to rhombic leaves mostly have coarse teeth, with the uppermost leaves entire. These fall-flowering Baccharis plants are dioecious, with male and female flowers on separate individuals. Their flowers are borne in numerous small, compact heads in large leafy terminal inflorescences, with the snowy-white, cotton-like female flower-heads showy and conspicuous at a distance.

The species is sometimes confused with the marsh-elder (Iva frutescens), with which it often co-occurs, but the Baccharis has its leaves alternate, while those of the Iva are opposite.
