Also known as: Bear's weed, Gum Plant, Holy Herb

Yerba santa is a member of the borage family native to the west coast of North America. Its common name means "Californian sacred herb." It is one of the first plants to resume growth after a wildfire because seeds in the ground will still germinate after a fire has passed through. Yerba santa is good to use in mass planting projects to revegetate overgrazed fields.
