Chempedak is a common tree in secondary forests and locally abundant in primary lowland rain forest in its area of natural occurrence. It is a long-lived sub-canopy tree. It grows up to 500(-1300) m altitude, often on wet hillsides. It is strictly tropical and always restricted to regions without a distinct dry season. The tree thrives on fertile well-drained soils, but prefers a fairly high water table (0.5-2 m); it can survive periodic flooding, even with acid swamp water (Sumatra: Palembang, Palopo).

The fleshy perianths which surround the seeds are eaten fresh or cooked. The flesh, typically yellow or orange, sometimes white to pinkish, is soft and mushy with a strong and very characteristic odour. The flavour is sweet, resembling durian and mango, and is considered by some to be superior to that of the jackfruit. In Malaysia 2-3 perianth-balls are pressed together, dipped in a mixture of rice-flour, sugar, milk and water, fried in oil for 10 minutes, and eaten as a delicacy. The seeds are eaten roasted or boiled (in salty water for 30 minutes) and have a nutty flavour. Young fruits are cooked in coconut milk and eaten as a curried vegetable or in soup. Young leaves are said to be used as a vegetable. The dark yellow to brown wood is strong and durable and used for building construction, furniture and boats. The bark can be used to make rope and the latex for the preparation of lime.
