Koaoha (Acacia koaia) is a rare and culturally significant Hawaiian native tree prized for its exceptionally hard, dense wood and golden puffball flowers. Plant in full sun to partial shade in well-drained soils and water regularly until established, after which it becomes more self-sufficient. As an endangered species, this tree is best suited for conservation plantings, native restoration gardens, or collectors dedicated to Hawaiian flora.
