California Bay Laurel
(Oregon Myrtle)

Umbellularia californica

A pungently aromatic evergreen tree or large shrub commonly found in somewhat moist shaded canyons and valleys below 5000'. It is scattered throughout the Transverse and Peninsular Ranges and blooms from December to May. California indians used the leaves as a flea repellant, and also to make a tea to treat headaches and stomach distress.  The wood is hard and polishes well, making it useful for turned objects.  It is also used as a flavor in cooking. The fruit is a round to ovoid drupe which is green at first and ages to dark purple with a light-brown smooth stone.
