What is the important subsistence crop throughout Oceania?

The most important and widespread subsistence crop in Oceania is the taro plant (Colocasia esculenta). It is a tropical perennial herbaceous plant that is widely grown in the Pacific islands for its large starchy edible corms. Taro corms are a staple food in many Pacific Island communities and provide a significant part of the local diet. The corms can be boiled, baked, steamed, or fried, and used to make a variety of dishes such as soups, stews, and puddings. Taro also has cultural and symbolic importance in many Pacific Island societies, and is often associated with fertility and abundance.
