Camphor laurel
Lauraceae - Cinnamomum camphora

What does it look like?

Evergreen tree up to 30m high, with a dense and spreading canopy.  Leaves are glossy green, alternate, 5-10cm long and 2.5-5cm wide.  Small, strong-smelling white flowers appear during spring. Fruit is round and 8-10mm in diameter, green when immature ripening to black, containing a single seed 5mm in diameter.  Mature trees can produce up to 100, 000 fruit per year. 

Why is it a problem?

As it is shade-tolerant and readily clonises exposed or disturbed areas, this plant is likely to displace native species. Forms a monoculture where no other plants can grow, which suggests it is allelopathic (this is when an organism produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other organisms).

Control Methods

Physical control:

  • Cut tree down and cover stump with thick plastic for 6-12 months.

Herbicide control:

  • Paint bark with X-tree basal; 
    OR
  • Cut stump treat with Pichloram gel (e.g. Vigilant) or 25% triclopyr: 75% water.
    OR
  • Over spray with triclopyr (300g/l) (e.g. Grazon) at 17ml per 10L water.

CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
