Lantana, common lantana (Lantana camara) is a declared pest in Western Australia (WA). This article describes the nature of the plant with links to requirements land owners/occupiers must adhere to and pest control methods.

Form: shrub — perennial

Status: present in WA

Native to Mexico, Central America, the Caribbean and tropical South America, lantana has naturalised around Kununurra and at scattered sites from Geraldton to Albany, but is most common around Perth along parts of the Swan and Canning Rivers. Lantana is a Weed of National Significance.

Appearance

Lantana is a perennial shrub, usually one to two metres high, but it can reach four metres. 

Stems: Long, often highly branched, square in cross section and hairy when young. The weedy forms usually have small sharp prickles along the angles.

Leaves: The oval leaves can be up to 100 millimetres long and are carried in opposite pairs up the stem. They are rough, due to being covered with small stiff bristles, and give off a strong smell if crushed.

Flowers: The small flowers occur in compact heads with 20-40 flowers in each head.  They can be yellow, pink, orange, red, or combinations of these colours.

Seeds: After flowering, lantana produces many small black berries, each five to seven millimetres in diameter and containing one seed.

It is toxic to livestock.
