Summary
Perrottetia sandwicensis, commonly known as Olomea or Hawaii Holly, is an evergreen perennial tree native to the Hawaiian Islands, where it thrives in the understory of wet forests and along stream banks. It exhibits a slow growth rate and can reach heights of 4-20 feet (1.2-6 meters), with a variable spread depending on environmental conditions. The Olomea has a bushy form with glossy, leathery leaves and small, greenish-white flowers that are not particularly showy, blooming in the spring. The flowers are followed by small, black drupes that are attractive to birds.
Olomea is valued for its lush foliage and suitability for naturalistic plantings in tropical gardens. It is also used in restoration projects within its native range due to its adaptability to wet conditions. In cultivation, it requires consistent moisture and does best in full sun to part shade. It prefers medium or slow-draining loam or clay soils, which mimic its natural habitat. While it is not widely used in urban landscaping, it can serve as an attractive feature in botanical gardens or as part of a native plant collection. Gardeners should be aware that it may require protection from strong winds and salt spray in coastal areas.CC BY-SA 4.0
