Environment

A tropical plant. It usually grows on the edges of rainforests. It suits humid locations. It also grows in shaded places in warm climates. In tropical Queensland it grows from sea level to 900 m altitude. In Africa it grows between 550-1,300 m above sea level.
More
A weed of light, open woodland and shaded waste places. Moist or dry thickets and forest, sometimes a weed in cafetales or other cultivated places, chiefly at low elevations but ascending to about 1,800 metres in Guatemala.
In or near rainforest or rainforest margins. Cocos (Keeling) Islands: A common weed in coconut plantations and disturbed sites in coralline sand.
