Where Yerba Santa Grows
This plant naturally grows in California and Oregon in the United States. You can find it in different kinds of places. It likes areas with chaparral, which are dry shrublands. It also grows in coast redwood forests.
What Yerba Santa Looks Like
Eriodictyon californicum is an evergreen shrub. This means it stays green all year round. It has a strong, pleasant smell. The plant usually grows about 3 to 4 feet (about 1 meter) tall. It spreads using woody rhizomes, which are like underground stems. This helps it grow in groups.
Its leaves are dark green and feel leathery. They are long and narrow, up to 15 centimeters (about 6 inches) in length. The leaves and small branches are covered with a shiny, sticky resin. Sometimes, you might see black fungi growing on this resin.
Yerba santa is similar to another plant called E. crassofolium. That plant grows more in Southern California.
Yerba Santa and Animals
This shrub can be a food source for some wildlife and farm animals. However, most animals do not like to eat it. This is because the plant tastes bitter. Even so, many insects, including butterflies, do feed on it.
The plant's flowers grow in a cluster. They are bell-shaped and can be white or purplish. Each flower is about one to two centimeters long.
How Yerba Santa Got Its Name
When this plant was first discovered, scientists placed it in a different group of plants. This group was called Wigandia. So, its first scientific name was Wigandia californica. Later, it was moved to the Eriodictyon group.
Traditional Uses of Yerba Santa

This shrub is very useful for helping damaged land recover. For example, it can be planted in areas where animals have eaten too much grass. It is also very good at surviving wildfires. After a fire, it can sprout new growth from its rhizomes. The plant's leaves also have a waxy, flammable resin.
