This plant can grow to at least 5 meters high and the four angled stem is covered with prickly, hooked spines that face in opposite directions. Its dense growths can also prevent the growth of other plants.
It is difficult to remove manually because of its thorns and readily grows back from plant remnants and the seed bank it leaves in the soil.
