Nature Walk – Zone 6
Hawaii’s native flora is as unique as it is diverse, with approximately 1,400 vascular plant taxa native to the islands, and nearly 90% of these are found nowhere else in the world. The rich tapestry of plants includes the native Akia plant, the Pohinahina, used medicinally by native Hawaiians, and the Kupukupu fern used in traditional Hula, are just a few examples of the islands’ botanical treasures. Conservation efforts are crucial to protect these species from threats such as habitat loss, invasive species, and climate change. Initiatives include surveying historic ranges, augmenting wild populations, and establishing new ones in safe harbors. The MTA Nature Walk was developed to highlight these plant species and other important fauna of Hawaiian culture and landscapes.
Zone 6 Plants
Plumeria
The Plumeria, with its vibrant blossoms and sweet fragrance, is a beloved symbol in Hawaii, despite not being native to the islands. Introduced in 1860 by Dr. William Hillebrand, a German physician and botanist, the Plumeria thrived in Hawaii’s warm climate and volcanic soil. Known locally as ‘Melia’, it is deeply ingrained in the cultural fabric of Hawaii, often used in leis and representing positivity and hospitality. The Plumeria’s adaptability is remarkable, growing from sea level up to 2,000 feet elevation and even thriving in colder climates when brought indoors during winter. With thousands of varieties now cultivated, the Plumeria continues to be a cherished part of Hawaii’s identity, celebrated for its ability to evoke the aloha spirit.
Mao Hau Hele
The Mao Hau hele, known scientifically as Hibiscus brackenridgei, is Hawaii’s state flower and a symbol of the islands’ unique flora. This vibrant yellow flower is endemic to Hawaii, meaning it is native and found nowhere else in the world. It thrives in the dry, full sun exposure of Hawaii’s landscapes, particularly at elevations ranging from 400 to 2,400 feet. The plant can grow up to about 10 feet tall and is recognized for its significant cultural importance to Hawaiians, who historically used it to produce a blue-gray dye for kapa cloth. Despite its beauty, the Mao Hau hele is classified as endangered, with its existence threatened by habitat loss and other environmental pressures. Efforts to conserve and protect this precious species are crucial to maintaining Hawaii’s natural heritage and biodiversity.
