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.

Pua Keni Keni Tree
The Pua Keni Keni, scientifically known as Fagraea berteroana, is a cherished plant in Hawaii, celebrated for its fragrant and beautiful flowers. Native to the tropical Pacific, this plant has found a special place in Hawaiian culture. The creamy white, tubular flowers of the Pua Keni Keni, which turn yellow over time, are a popular choice for making traditional leis, symbolizing hospitality and aloha spirit. In the past, these flowers were sold for ten cents each, which is how the plant got its Hawaiian name, meaning “ten cent flower”. The Pua Keni Keni is not only valued for its aesthetic appeal but also for its use in creating fragrant oils when soaked in coconut oil. This versatile plant thrives in a variety of soils and requires full sun exposure, making it well-suited to Hawaii’s climate. Its wood is also utilized for crafting tool handles and other small wooden items, showcasing the plant’s utility beyond its ornamental use. The Pua Keni Keni’s enchanting fragrance and striking flowers continue to make it a beloved feature in Hawaiian gardens and cultural practices.
Variegated Hala Tree
The variegated Hala, or Pandanus tectorius, is a distinctive plant indigenous to Hawaii, known for its cultural and ecological significance. This small tree can grow up to 30 feet in height and is recognized by its long, blade-like leaves that are arranged in a spiral pattern, creating a unique visual effect on the trunk as they fall. The variegated form of this species is particularly sought after for its aesthetic appeal, with leaves that display a mix of colors, adding to the plant’s ornamental value. Traditionally, the Hala tree has been an integral part of Hawaiian life, with its leaves (lau hala) being used in weaving a variety of items such as mats, hats, and baskets. The tree is also known for its prop roots (ule hala) that provide support and its gender-specific characteristics, with female trees producing large, segmented fruits and male trees producing fragrant flowers. Adaptable to a range of coastal environments, the Hala thrives in moist locations and can be propagated by seeds, which are traditionally soaked to speed germination. The Hala’s resilience and utility make it a cherished part of Hawaii’s natural heritage and a living symbol of the islands’ rich biodiversity.
Gardenia
Gardenia jasminoides, known as the common gardenia, thrives in the Hawaiian climate, offering a delightful fragrance that enhances gardens and homes throughout the islands. In Hawaii, the gardenia is not only appreciated for its aromatic presence but also for its cultural significance, often used in leis and traditional ceremonies. The plant prefers a sunny location at higher elevations or filtered sun closer to sea level, thriving in moist, rich, and acidic soil with a pH of 5.0 to 5.5. Pruning after blooming helps keep the gardenia compact and encourages new growth, ensuring that this fragrant flower continues to be a beloved feature in Hawaiian landscapes.
