Native Hawaiian plants are easily visible from any trail within HVNP, with the most common including ‘ōhi’a, koa, uluhe fern, and hapu’u tree ferns. Hawaii Volcanoes National Park is an expansive park with many diverse ecosystems represented within the main crater, shoreline, and Kahuku areas of the park. The path walking is easy but uneven walking up the hillside. Over 200 species can be found within the garden, from plants culturally value to Native Hawaiians such as kalo, to rare plants such as hala pepe and kōki’o. Walking through the garden, you will pass through areas representing coastal, dry forests, agricultural, and wet forest zones. Interpretive signs posted throughout the garden will inform you of the ethnobotanical values of the plants. Ethnobotany is the study of the role of plants within a culture, including folklore, uses, and agricultural customs. Greenwell Ethnobotanical Gardens is a fifteen acre garden dedicated to to showcase plants that were in Hawaii before the arrival of Captain James Cook in 1778. Located in Captain Cook twelve miles south of Kailua Kona, Amy B.H.
