What is Hibiscus Arnottianus?
I’m Ferb Vu, and I’ve been captivated by the beauty of the Hibiscus Arnottianus for years. This Hawaiian native, also known as the Koki’o ke’oke’o, boasts a unique charm that sets it apart from other hibiscus varieties.
Fragrant & Elegant: Unlike most hibiscus, the Koki’o ke’oke’o possesses a subtle, delightful fragrance. Imagine waking up to a hint of sweetness in the morning air, courtesy of these blooming beauties.
Pinwheel Perfection: The star of the show is undoubtedly the flower. Pristine white petals unfurl into a pinwheel shape, reaching up to four inches in diameter. A vibrant splash of color comes from the central staminal column, which ranges from pink to red, creating a stunning contrast.
Evergreen Allure: Unlike many flowering shrubs, the Koki’o ke’oke’o maintains its lush foliage year-round. Its oval leaves, adorned with smooth or slightly toothed edges, often boast red veins and stems, adding another layer of visual interest.

Hibiscus Arnottianus vs. Hibiscus Rosa-Sinensis
While the Koki’o ke’oke’o and the common Hibiscus Rosa-Sinensis (Chinese Hibiscus) share the hibiscus name, they have distinct personalities.
Flower Power: The Chinese Hibiscus is renowned for its vibrant, large flowers in a kaleidoscope of colors. In contrast, the Koki’o ke’oke’o offers a more delicate charm with its pristine white blooms.
Fragrance Factor: The Chinese Hibiscus is generally not fragrant, while the Koki’o ke’oke’o entices with its subtle, sweet scent.
Climate Champions: Both varieties thrive in warm climates. However, the Koki’o ke’oke’o tolerates some light shade, while the Chinese Hibiscus prefers full sun.
Endangered Status: Sadly, the Koki’o ke’oke’o’s native habitat on Molokai, Hawaii, faces threats. Conservation efforts are underway to protect this special plant.
Choosing Your Champion: If you crave a fragrant, elegant bloomer, the Koki’o ke’oke’o is your champion. For a show of vibrant color, the Chinese Hibiscus reigns supreme.
How to care for Koki’o ke’oke’o?
Bringing the Koki’o ke’oke’o’s magic to your garden is easier than you might think. Here’s a quick guide:
Location, Location, Location: Full sun is ideal for optimal flowering and disease resistance. However, it can tolerate some light shade, as long as it receives more light than shade.
Watering Wisdom: Consistency is key. Water your Koki’o ke’oke’o frequently, especially during hot weather. Aim for moist, well-drained soil.
Feeding Frenzy: During spring and summer, provide a boost with organic fertilizer. Choose a powder formula for potted plants and a liquid option for in-ground specimens.
Potted Paradise: The Koki’o ke’oke’o adapts well to container life. Ensure your pot has drainage holes and choose a potting mix specifically formulated for flowering plants.
Propagation Pointers: This beauty can be propagated from fresh seeds. However, be aware that seedlings may not be identical to the parent plant due to hybridization. Hand pollination can help ensure true-to-type offspring.
