Noni grows in shady forests as well as on open rocky or sandy shores. It reaches maturity in about 18 months and then yields between 4–8 kilograms (8.8–18 lb) of fruit every month throughout the year. It is tolerant of saline soils, drought conditions, and secondary soils. It is therefore found in a wide variety of habitats: volcanic terrains, lava-strewn coasts, and clearings or limestone outcrops. It can grow up to 9 metres (30 ft) tall, and has large, simple, dark green, shiny and deeply veined leaves.
