Umbellularia californica
B tier
Umbellularia californica is the botanical species of California bay / Oregon myrtle—a laurel-family tree native to California and Oregon with peppery-camphor leaves far more aggressive than Laurus nobilis. Botanical clarity prevents recipe disasters. If using, start with a fraction of a leaf and taste the pot. Nuts of the tree have separate traditional uses; this entry concerns the culinary leaf comparison to bay.
