Native to the Atlantic and Gulf Coastal Plain, Baccharis halimifolia is recognized by its broad, distinctly rhombic, coarsely serrate basal leaves, pyramidal, leafy arrays, and cypselae with large fluffy pappi. The plants are often to 600 cm; the basal leaves might be missed by collectors. Forms with relatively narrow leaves are especially common in Arkansas, Louisiana, and east Texas. These may be the result of hybridization and introgression with B. neglecta, in areas where they are known to hybridize (D. J. Zanowiak 1991), or with B. angustifolia. Hybrids between B. halimifolia and B. angustifolia are known from Florida as well. Baccharis halimifolia has been introduced to Australia and France. In Australia it infests large areas along the coast of southern Queensland and New South Wales. Its success as an invasive weed is attributed to production of a large number of seeds that are widely dispersed by the wind, shade tolerant germination and seedlings, tolerance to wet soils and salinity, and ability to resprout after a fire (W. E. Westman et al. 1975). The leaves of B. halimifolia contain a cardiotoxic glycoside known to cause the death of sheep if they eat about one percent of their body weight in leaves.
