Countless species of plants and flowers are found throughout Hawaii. However, with the introduction of so many diverse indigenous varieties, it’s not always easy to find native plant life. Thankfully, you can visit the botanical garden in Waimea Valley in Haleiwa to see the various native shrubs and trees they conserve, including those listed here.

Native Flora to See at the Waimea Valley Botanical Garden

1. Koki‘o Ke‘oke‘o

Also known as Hibiscus waimeae, the Koki‘o ke‘oke‘o plant is considered both a shrub and tree, capable of growing up to 20 to 30 feet. While there are two subspecies of hibiscus native to Hawaii and both have light green leaves with velvety underlayers, this one is known for its larger, fragrant white flowers.

These unique flowers are the only ones in the genus Hibiscus that give off a scent. Since the fragrance is only present at dawn and dusk, schedule your trip for the morning or evening hours if you hope to experience it.

2. Hāpuʻu

Ferns have long been a part of Hawaiian culture. The hāpuʻu, scientifically known as Cibotium chamissoi, is a woody shrub that starts with a curled up shoot that will unfurl as it grows. It can be found in the wetter forests of Oahu and is often recommended for landscaping to combat invasive Australian fern species. 

3. Koai‘a

Although once prevalent over the lowlands of the main Hawaiian Islands, koai‘a trees are now rare and listed as an “at risk” species. Also known as Acacia koaia, it is the smaller cousin to the more widespread native koa species most plant and hardwood lovers are familiar with. While it’s seldom used in woodworking these days, koai‘a has an even harder wood and is praised for its beautiful gnarled grain. 

The Waimea Valley Botanical Garden is home to 52 themed gardens and over 5,000 types of tropical and subtropical plants. This includes varieties native to Oahu that have a part in Hawaiian culture. Tours are available every Thursday. On the first and third Sunday of each month at 12:30 pm, a botanical specialist guides the group.
