California Bay (Umbellularia californica) is an evergreen, hardwood tree native to the Western coastline of America, from Oregon to California. Its distribution can be as far inland as the Sierra Nevada mountains, appearing in redwood forests, woodlands and pine forests. These hardwood trees can grow up to 30m tall with a trunk width of approximately 80cm.

The leaves are particular fragrant, with a scent not too dissimilar from bay leaves. The leaves are long and narrow with smooth edges and a dark green hue, and the flowers are small and yellow. It also bears small green berry like fruits called ‘California Bay Nuts’, which turn purple when matured. Many people liken the fruits to small avocados, this is because the pit is also surrounded by a rich, oily flesh.

California bay has a number of other colloquial names that you may be familiar with. You may recognise it as: Oregon myrtle, pepperwood, California laurel, headache tree, mountain laurel, spicebush and also balm of heaven.

Cultivation and History of California Bay

California Bay has a long history of usage within the Native American culture. They collected the leaves and fruits to use in a variety of recipes and herbal remedies. Today they are no longer cultivated commercially for culinary usage. Therefore only foragers and wild food enthusiasts tend to harvest the leaves.

Many people may choose to grow their own California bay. Seed germination can be difficult but very rewarding. Collect the seed from a fruit and crack it open slightly with a nutcracker, taking care not to destroy the casing. Place the seed within a bag of potting soil and perlite and place into a refrigerator (30-42 degrees Fahrenheit), this mimics the conditions a seed would typically endure outside. You should see a seedling after approximately 85 days, remove the seedling and plant it in a small container. Keep the small plant indoors for about one year, until mature enough for outside planting.


Similar to Mediterranean bay, you cannot digest California bay leaves. So although it isn’t toxic, you should not consume the leaves whole. Inhaling or touching the leaves can occasionally cause irritation in some individuals. The substances umbellulone and safrole are believed to cause this.
