context_page_description: Baccharis halimifolia is a North American species of shrubs in the daisy family. It is native to Nova Scotia, the eastern and southern United States, eastern Mexico, 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.
context_section_description: In Australia, B. halimifolia is an invasive species along the coast of southern Queensland and New South Wales.  As biological control the rust fungus Puccinia evadens is used.
  The species has also become naturalized in Europe and in New Zealand.
  In the northeastern United States, the species has become common well inland of the shrub's natural range along various major highways where road salt is heavily used, sometimes forming conspicuous displays when flowering in the fall, as along I-95 in Howard County, Maryland.
