Habit 

Usually flowers and fruits as a shrub about 2-5 m tall, but can reach 6 m

Impact and control methods

It has been listed as a noxious weed in South Africa and Hawaii.(prohibited plants that must be controlled. They serve no economic purpose and possess characteristics that are harmful to humans, animals or the environment)
