Scaevola gaudichaudii, commonly known as Ridgetop Naupaka, is an evergreen shrub endemic to the Hawaiian Islands, where it is found in dry, coastal areas and lowland shrublands. It can grow up to 6 feet tall and spread to 8 feet in diameter. The Ridgetop Naupaka has a dense, rounded form with succulent leaves that help it conserve water in its arid native habitat. It produces clusters of fan-shaped, yellow flowers throughout the year, which are mildly fragrant and attract pollinators. The flowers give way to small, purple drupes that are enjoyed by local bird species.

The Ridgetop Naupaka is valued for its ability to withstand harsh, dry, and windy conditions, making it an excellent choice for xeriscaping and coastal gardens where other plants might struggle. Its tolerance for salt spray also makes it suitable for seaside plantings. In cultivation, it requires minimal maintenance once established, needing only well-drained soil and full sun exposure. It is often used in restoration projects to stabilize soil and provide habitat for native fauna. While it is generally disease-resistant, it can be susceptible to root rot if overwatered or planted in poorly drained soils. It is not known to be invasive outside its native range.CC BY-SA 4.0
