Lantana is already here but we’re working to get rid of it.
Why it is a pest plant
|Production threat||Environmental threat||Public threat|
Lantana is a long-lived scrambling evergreen shrub, native to tropical America. It was originally brought to New Zealand as an ornamental shrub due to its attractive flower.
Lantana can totally smother and replace other species, forming dense thickets causing loss of habitat. It is ‘allelopathic’, which means it releases toxins into the surrounding soil suppressing other plants. It is also toxic to livestock.
Its woody taproot will produce suckers when broken. Lantana grows easily by layering when its branches touch the ground and put roots down. It will grow from vegetative fragments, so it is recommended that these are disposed of appropriately, preferably to a landfill. Lantana is a prolific producer of seeds which are then spread by birds.
Lantana is a low, multi-branched, scrambling perennial shrub with a strong root system. It grows 2-4m tall and has backwards-pointing prickles on its stems.
