Nam Nam tree (Cynometra cauliflora), also called Pokok Katak Puru in Malay, is a beautiful tropical tree from the legume family (Fabaceae). The tree originates from Myanmar to West and Central Malesia and is known for its unique fruiting pattern directly on the trunk and large branches.

Overview The nam nam tree is a medium to large tree that can reach 15-20 meters in height. The tree is valuable both as a fruit producer and for its decorative value. The fruits grow cauliflorous, directly from the trunk and older branches.

Appearance The tree has dark, fissured bark and elegant, compound leaves with many small leaflets. The leaves are dark green and glossy. The tree looks elegant year-round thanks to its foliage coloring.

Fruiting The fruits are brown, kidney-shaped, and approximately 2-3 cm long. They grow directly from the trunk and thick branches in large numbers. The fruits have sweet, hearty flesh that is edible and locally eaten in Southeast Asia. Each fruit contains 1-2 large seeds.

Climate Requirements The nam nam tree grows in warm, tropical climates with regular rainfall. The tree is not frost-tolerant and requires temperatures above 15 degrees Celsius. Ideally, the tree grows in zones with temperatures above 20 degrees.

Watering During the growing season, the tree needs regular watering. Offer deep watering rather than shallow sprinkling. Once established, the tree tolerates some drought, but regular watering significantly improves fruit production.

Cultivation and Propagation The tree is usually grown from seed. Seeds should be fresh and sown in nutrient-rich seed compost. Seedlings grow quickly and can begin fruiting within 3-4 years.
