Umbellularia californica is a large hardwood tree native to coastal forests of California and slightly extended into the state of Oregon.[1] It is endemic to the California Floristic Province. It is the sole species in the genus Umbellularia.

 

The tree was formerly known as Oreodaphne californica.[2] In Oregon, this tree is known as Oregon myrtle, while in California it is called California bay laurel, which may be shortened to California bay or California laurel. It has also been called pepperwood ,spicebush, cinnamon bush, peppernut tree, headache tree, mountain laurel, and Balm of Heaven.

 

The tree's pungent leaves have a similar flavor to bay leaves, though stronger, and it may be mistaken for Bay Laurel. The dry wood has a color range from blonde (like maple) to brown (like walnut). It is considered a world-class tonewood and is sought after by luthiers and woodworkers.

 

The tree is a host of the pathogen that causes sudden oak death.
