Baccharis salicifolia is a blooming shrub native to the sage scrub community and desert southwest of the United States and northern Mexico, as well as parts of South America. Its usual common name is mule fat;[3]: 126 it is also called seepwillow or water-wally. This is a large bush with sticky foliage which bears plentiful small, fuzzy, pink, or red-tinged white flowers which are highly attractive to butterflies.[4] It is a host plant for the larval stage of the fatal metalmark butterfly, and the adult stage also nectars on the flowers.[5]

Another use is fire starting. Dried Baccharis salicifolia has a very low ignition temperature, very similar to the dried yucca stalk. It can be used for spindles and hand-drill shafts.
Galls
