Yerba Santa is an evergreen shrub that grows 3 to 8 feet tall. It has many straight, protruding branches. The long, lanceolate leaves are dark green and grow on a short stem. The mature leaves often feel sticky and may even appear sooty or black. This is the result of a common fungal attack that forms on mature Yerba Santa bushes. The pink and purple flowers bloom in spring. The gray fruit surrounds a small seed capsule containing small hard black seeds. The leaves have a pungent and unpleasant smell and a bitter taste.

🛑 Yerba Santa can interfere with the body's ability to absorb iron and other important minerals, which is why it is not recommended for women who are breastfeeding or pregnant.

This type of shrub is used to revegetate damaged or disturbed areas, such as overgrazed pastures. It is highly adapted to fire, sprouting from rhizomes after a wildfire and developing a waxy film of flammable resins on its leaves
