Legal Status 
Target Species

A dense spreading or erect shrub or tree up to 6m high. The leaves are smooth and up to 100mm long and form sharp-pointed needles 30-50mm long and are dark-green to grey-green in colour.There are 46–84 flowers, cream in colour and fragrant, forming elongated, axillary clusters up to 20mm long and flower from June to September. Seeds consist of woody capsules approximately 25mm long and 20mm wide.

Where does this species come from? 
H. drupacea is endemic to coastal regions of south-western Australia and some islands in the adjacent Recherché Archipelago. The natural vegetation where H. drupacea occurs is evergreen forest and xerophilous woodland with a Mediterranean-type climate.
Why is it a problem? 
H. drupacea is a serious invader of the floristically rich and unique mountain fynbos in the Western Cape Province, South Africa. Dense stands of woody alien plants can alter the composition of natural plant and animal communities. They also lead to increased fire intensities that may kill plant species that regenerate vegetatively and seeds on or in the soil. The most obvious impact of dense stands of H. drupacea on the native vegetation is the reduction in species richness and the altered appearance of the landscap
Means of reproduction? 
Spread by seed. Some species sucker from the roots.
