Baccharis

It is found throughout the Americas, distributed mainly in the warmer regions of Brazil, Argentina, Colombia, Chile and Mexico,[4] with B. halimifolia ranging northward along the Atlantic Coast to the southern tip of Nova Scotia in Canada.

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.

[7] Baccharis are used as food plants by the larvae of some Lepidoptera species, such as the swift moths Phymatopus californicus and P. hectoides.

The Coleophora case-bearers C. linosyridella and C. viscidiflorella are polyphagous species whose larvae have been recorded on the Bush Baccharis as well as other plants.

[8] Several species of Baccharis are of interest for cultivation, as the dense but flexible stem structure makes for a good windbreak.
