|Umbellularia californica is a spreading evergreen tree which can reach 75 feet tall, 100 feet wide in the wild. Foliage is aromatic and leathery dark green, some find the aroma unpleasant, even causing headache, while others use the leaves as a substitute for Sweet Bay in cooking. Creamy yellow flowers appear in late spring, followed by an inedible purple olive-like fruit. It has a tendency to sucker and it is difficult to grow other plants underneath it, also sheds leaves and litter, so best not used by paved areas, however it is useful as a large hedge or screen. Can be subject to sooty mold from aphids or scale infestation. Native to California, Oregon.
