What does lantana look like?

• Lantana is a tough, evergreen shrub growing to 4 metres in height. The stems are squarish and hairy, rough to the touch and have short recurved prickles. The leaves are opposite, oval, hairy underneath and toothed along the margin. Both stems and leaves give off an offensive smell when crushed. The tube-like flowers occur in brilliant clusters that vary in colour between plants and during the life of a single plant. The fruit is a succulent purple berry carried in clusters of 1 to 20 fruits.
• Seeds germinate at any time of year. Flowering commences in early summer of the second growth season and continues until March or April. New canes are produced from the crown and lateral roots in early spring.
• Spread is by seed and root suckering. Established thickets increase in size by suckering and seedling growth on the edges of thickets. Long distance spread of seeds results when birds eat the fruits and void the seed away from the parent plant. Lantana is also spread as part of the ornamental plant trade.

Impacts of lantana

• Lantana is a serious environmental weed, and can invade native vegetation, shade out native species and increase fire risk. Lantana is also a serious weed of pasture, certain crops and forestry plantations. Lantana is toxic to stock.
