Species include:
- English laurel (Prunus laurocerasus) also known as cherry laurel
- Portuguese laurel (Prunus lusitanica) also known as Portuguese cherry laurel
English and Portuguese laurels are considered naturalized in Oregon, Washington, California, and British Columbia. These species are large evergreen shrubs or small trees and are used for landscaping, usually as a hedgerow. They are often planted as ornamentals because of their resemblance to cherry trees but can escape and infest natural areas.

Impact:
- Ornamental laurels can grow very large, crowding out native understory trees, shrubs, and groundcovers.
- Both species’ berries, leaves, and stems are toxic to eat.
Impact:
- Hand pulling small laurels is effective in damp soils, it is important to remove as much of the root as possible.
