ID Characteristics

General: Cherry Laurel is a dark green shrub, widely used as an ornamental hedge plant.

Flowers: Tiny, very fragrant white flowers that form in upright clusters.

Stem: Green stems near newer leaves, brown and woody branches further down the plant. Cherry Laurel is a broad, dense, spreading, evergreen shrub that can reach 3 – 5 m tall and 6 – 7 m wide.

Leaves: Dark and waxy evergreen leaves. Finely-toothed with an oblong shape, tapering sharply at the tip. Grow in an alternating pattern along the stem, sprouting from a short stalk. Leaves are 5 – 18 cm long.

Fruits: Black drupes with a large stone, which ripen in midsummer. They are bitter and essentially inedible for humans, but consumed by birds and other animals.

Similar Species
  • Invasive:

Spurge Laurel (Daphne laureola): From the same genus as the Cherry Laurel, this invasive plant grows rapidly, out-competes native vegetation, and poses a serious health risk to people and pets for its poisonous sap. It can be distinguished by its strongly fragrant yellow-green flowers and leaves in a whorl formation.

Habitat and Origin

Origin: Originally native to southwestern Asia and southeastern Europe, Cherry Laurel is now widely used as an ornamental hedge in North America.

Habitat: Cherry Laurel will grow in full sun or partial shade. It prefers moist, rich, and well-drained soils.

Current Distribution

Propagation & Vectors of Spread

Cherry Laurel reproduces by seeds; it can also reproduce vegetatively by creating new shoots from cut stems and roots.

Cherry Laurel primarily spreads through its seeds, which are dispersed by birds and animals that eat them. The horticulture trade is another prevalent vector of spread for Cherry Laurel, as the plant is often used ornamentally. Lastly, cultivation stimulates new growth, so gardeners may inadvertently be spreading the plant in their efforts to work the soil.

Ecological and Health Impacts

Ecological:

  • Reduces biodiversity
  • Outcompetes native forest species
  • Could potentially crossbreed (hybridization)

Health:

  • Berries are poisonous to humans

Economical:

  • Large thickets can become a nuisance for landowners and often require significant maintenance or removal
What Can I Do?

Cherry Laurel is found in the Lower Mainland (BC), but there are currently no reports of it in the Sea to Sky Region, so PREVENTION of further spread is key.

DO:

  • Regularly monitor properties for infestations.
  • Avoid planting Cherry Laurel
  • Choose alternative native plants for garden hedges, such as salal (Gaultheria shallon)
  • Ensure soil and gravel are uncontaminated before transport
  • Remove plant material from any equipment, vehicles, or clothing used in infested areas and wash equipment and vehicles at designated cleaning sites before leaving these areas.
  • Minimize soil disturbances (e.g. use grazing plans that prevent soil exposure from overgrazing), and use seed mixes with dense, early colonization (e.g. alfalfa or barley) to re-vegetate exposed soil and resist invasion.
  • Ensure plants (particularly flowering heads or root fragments) are bagged or covered to prevent spread during transport to designated disposal sites (e.g. landfill).

DO NOT:

  • Don’t unload, park, or store equipment or vehicles in infested areas; remove plant material from any equipment, vehicles, or clothing used in such areas, and wash equipment and vehicles before leaving infested areas.
  • Do not plant Cherry Laurel, no matter how well-contained the area might seem.
  • DO NOT COMPOST!

 

Control

Mechanical

  • Clip the plant before it flowers, or remove all the spent flowers before they can form fruit.
  • Smaller plants can be dug up, taking care to remove all roots.
  • Larger plants can be cut as close to the ground as possible (by hand or chainsaw), and then stumps can be dug out, or chemical control options used. Any cuttings should be bagged and disposed of properly, in a landfill.
  • Monitor any remaining stump for re-growth.

Chemical

  • After removing branches and exposing the stump, the remaining plant can immediately be sprayed with glyphosate or triclopyr.
  • Alternatively, the stump can be treated by frilling (chipping notches around the trunk and applying herbicide to the fresh cuts), or injecting herbicide directing into the trunk (using required injection tools).
  • These methods can be used on large stems that have not been cut down, although it may be easier to first cut off smaller side stems and foliage to access the main trunk.
  • We recommend that any herbicide application is carried out by a person holding a valid BC Pesticide Applicator Certificate. Before selecting and applying herbicides, you must review and follow herbicide labels and application rates; municipal, regional, provincial and federal laws and regulations; species-specific treatment recommendations, and site-specific goals and objectives.

Biological

  • Biological agents are currently not available in Canada for this species.
