Family: Moraceae

Artocarpus camansi, commonly known as breadnut or chataignier, is a tropical tree valued for its starchy seeds, which are edible after cooking. Native to New Guinea and surrounding regions, it has been introduced to Hawaii, where it is occasionally cultivated in home gardens for its nutritious seeds. The tree produces large, round fruits with a tough green skin and a soft interior packed with seeds that are rich in protein and carbohydrates, making them a traditional staple in some Pacific Island cultures. Breadnut trees are relatively low-maintenance and can provide shade, edible harvests, and an attractive tropical landscape feature.

Although not considered invasive in Hawaii, breadnut trees can spread naturally through seed dispersal by animals, and they may establish in favorable environments. Gardeners should be aware that while the tree is generally safe, its large size and extensive root system can impact nearby plantings or structures if not managed. Overall, Artocarpus camansi is a valuable and culturally significant plant that can be enjoyed responsibly in Hawaiian gardens.
