Lantana (Lantana camara) is a perennial herbaceous plant and shrub with showy flowers that change color as they mature. In Australia and several parts of the United States (AL, AZ, CA, FL, GA, HI, LA, MS, NC, OK, SC, TX, and UT), lantana is considered an invasive weed and rapidly forms dense thickets.

Lantana has compact, flat-topped flower heads and vary in coloration from yellow to orange to red or from white to pink to lavender. The flowers are tubular, 4-petaled and occur nearly all year long, and the central flowers and outer flowers in the clusters are different colors.

Lantana Toxic Components

All parts of L. camara contains pentacyclic triterpenoids which are damaging to the liver when ingested by horses. It can also cause photosensitization.

Signs of Lantana Poisoning

Early signs of lantana poisoning include depression, loss of appetite, constipation and frequent urination, followed jaundice. Photosensitivity is usually followed by death, typically occurring 1–4 weeks after the first signs of illness. Administering activated charcoal orally may help.


  • Depression
  • Loss Of Appetite
  • Constipation
  • Frequent Urination
  • Jaundice
  • Ocular Discharge
  • Photosensitivity


MANUAL CONTROL: Hand grubbing, hand cutting and hand pulling is effective for small infestations or scattered plants over large areas.

MECHANICAL CONTROL: Mechanical control is effective for control of mature lantana infestations which over a large area. Bulldozing or slashing plants followed by herbicide control of seedlings and replacing with pasture or other vegetation cover.

FIRE CONTROL: Fire is effective to reduce the height and density of lantana thickets, however it rarely kills the plants, as they recover quickly.

CHEMICAL CONTROL: Control with herbicides is the most practical and effective method however it is also the most costly. Pink lantana are better controlled with herbicides then other colored-plants.
