California Bay
Umbellularia californica
Medium · Some experienceAbout California Bay
California Bay Laurel is an aromatic California and Oregon native evergreen tree reaching 20-80 feet with dense dark green lance-shaped leaves that have the most intensely pungent spicy scent of any culinary herb—far stronger than Mediterranean bay. Native throughout California's coastal mountains and Central Valley foothills, it is used as a substitute for bay laurel in cooking but with extreme restraint. The volatile oils are so powerful that crushing a leaf near the face can cause headaches and temporary loss of smell.

History
Umbellularia californica is native to California and southwestern Oregon, growing in mixed-evergreen forests, oak woodland, redwood forests, and stream-canyon habitats from coastal northern Baja California north through the California coast and into southern Oregon as far north as Douglas County. It grows variably from a multi-trunked shrub on exposed coastal sites to a tall single-trunked tree 20-30 meters tall in sheltered forest habitat, with glossy elliptical leaves emitting an intensely pungent, camphor-like aromatic scent when crushed. The leaves have been used for centuries as a substitute for Mediterranean bay laurel (Laurus nobilis) in California and Oregon regional cuisine, though the California species' aroma is significantly stronger and more camphor-scented than Mediterranean bay — recipes typically use smaller quantities.
Inhaling the crushed leaves too deeply can cause a short-duration headache sometimes called "myrtlewood headache" or "umbellulone headache" (named for the volatile compound umbellulone responsible). The beautifully figured pale-yellow to olive-green wood is the exclusive raw material for the distinctive "myrtlewood" tourist-craft industry of the Oregon Coast — since the early 20th century, small family-run myrtlewood shops along the southern Oregon coast (particularly between Coos Bay and Gold Beach) have produced turned bowls, clocks, candlesticks, and souvenir items from harvested old-growth myrtlewood trees; the industry is a distinctive part of Oregon coast culture and identity.
Indigenous California peoples including the Pomo and Yuki used the leaves for various medicinal purposes. Hardy to approximately USDA zone 7-8.

Paired with power, its overwhelming aromatic scent commands respect and a certain restraint; one leaf is more than enough in a pot of soup.
