MTA Nature Walk – Zone 3
Nature Walk – Zone 3
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 3 Plants
Variegated Hau Tree
The variegated Hau tree, scientifically known as Hibiscus tiliaceus, is a stunningly beautiful and culturally significant plant in Hawaii. With its striking multicolored leaves that display a vibrant mix of red, pink, white, and green, it’s a visual delight for any garden or landscape. This species, which is possibly indigenous to Hawaii, has been an integral part of the Polynesian culture. The Hau tree’s fibers were traditionally used to make cordage, essential in everyday life, while its light wood was crafted into canoe parts and fishnet floats. Medicinally, the sap and flower buds were used in remedies for various ailments. The flowers of the Hau tree are particularly notable; they bloom year-round, opening yellow in the morning and transitioning to red by day’s end. These trees are not only a testament to the rich biodiversity of Hawaii but also stand as a symbol of the deep connection between the natural world and cultural practices of the Hawaiian people.
Kou Tree
The Kou tree, scientifically known as Cordia subcordata, is an indigenous species to the Hawaiian Islands, flourishing in the coastal areas and sunny zones at low elevations from 150 to 1000 feet. This resilient tree is recognized for its drought, wind, and salt tolerance, making it a staple in Hawaiian landscapes. Traditionally, the Kou wood was highly valued for carving due to its ease of cutting and the beauty of its grain, often used to create calabashes, dishes, and other utensils. The leaves of the Kou tree hold cultural significance as well; they were utilized to make a warm brown to red dye for kapa (bark cloth) and to dye fishing lines by fishermen. The tree’s orange flowers are not only visually striking but also serve as a material for crafting beautiful lei. The Kou tree’s presence in Hawaii is deeply interwoven with the islands’ history and culture, once thought to be introduced by Polynesians, but now recognized as a native species that predates human arrival.
