Beach naupaka
Scaevola taccada, family Goodeniaceae
A salt-tolerant shrub with fan-shaped white flowers on tropical beaches
Beach naupaka is a large coastal shrub found on sandy shores and coral beaches across the Indo-Pacific. Its thick, yellowish-green leaves and distinctive white, fan-shaped flowers bloom year-round. People use it for coastal protection, landscaping, and in traditional medicine, and it is among the first plants to colonise new sandbanks.
- Grows directly on tropical beaches, tolerating salt spray
- White, fan-shaped flowers bloom all year
- Fruit floats and spreads by ocean currents
- Used to prevent coastal erosion and as a windbreak
- Leaves were used as famine food in the Maldives
What does Beach naupaka look like?
Beach naupaka is a sprawling shrub that can reach 3 to 10 metres tall. Its leaves are thick, fleshy, and yellowish-green, crowded at the tips of the branches. The flowers are white, sometimes striped with violet, and grow in fan-like clusters, each with petals about 2 to 2.5 cm long. The fruit is round, fleshy, and turns from green to white when ripe. The plant often forms dense thickets along sandy or rocky beaches exposed to salt spray.
Where does Beach naupaka come from?
This shrub is native to the tropical coasts of the Indo-Pacific, including southern China, Southeast Asia, northern Australia, and many Pacific islands. It thrives in beach crests and coral sands, often as one of the first plants to colonise new sandbanks. Its seeds float and are spread by ocean currents, helping it reach distant shores. There has been confusion over its scientific name, but Scaevola taccada is now widely accepted.
When and how Beach naupaka blooms
Beach naupaka blooms throughout the year. It grows best in well-drained sandy soils close to the sea, tolerating salt spray but not frequent flooding by seawater. The plant can be grown from seeds, which float and travel long distances, or from cuttings. It is often found in loose communities with other coastal plants like coconut palms and beach morning glory.

How Beach naupaka is used
People plant beach naupaka to prevent coastal erosion and as a windbreak to protect other plants from salt spray. In some Pacific islands, it is used in landscaping. The shrub provides shade and shelter for nesting green turtles. Parts of the plant are used in traditional medicine in Polynesia and Asia, and its leaves were used as famine food in the Maldives. Chamorro spearfishermen used drops from the plant for eye irritation.
Kinds of Beach naupaka
Scaevola taccada is sometimes confused with Scaevola plumieri, a related species found on Atlantic coasts. The two differ in fruit colour and calyx shape: S. taccada has white fruit with persistent calyx lobes, while S. plumieri has black fruit and shorter calyx lobes. S. taccada is also known by the synonym Scaevola sericea.
