Taro, or kalo, held immense cultural and nutritional significance in ancient Hawai’i. Hawaiians cultivated numerous taro varieties in complex agricultural systems. They used taro to make poi, a staple food rich in nutrients.

Coconut palms provided sustenance and materials for daily life. Hawaiians consumed coconut water and meat, while using the husks and leaves for various purposes.

Breadfruit, known as ‘ulu, was another important food source. Its starchy fruit could be cooked in multiple ways or preserved for later use.

Sweet potatoes, called ‘uala, thrived in drier areas where taro cultivation was challenging. These versatile tubers supplemented the Hawaiian diet and helped expand settlements to less fertile regions.

Introduction of Non-Native Species

Polynesian voyagers brought essential food plants to Hawai’i, now known as “canoe plants.” These included:

• Banana (mai’a)
• Sugar cane (ko)
• Yams (uhi)
• Mountain apple (‘ohi’a ‘ai)

These introduced species adapted well to Hawaiian ecosystems and became integral to the native diet and culture.

European and Asian arrivals later introduced additional plant species. Some, like pineapple and macadamia nuts, became synonymous with Hawaiian agriculture. Others, such as guava and strawberry guava, spread rapidly and impacted native ecosystems.
