Hibiscus kokio, also known as Kokiʻo ʻula or Kauaʻi hibiscus, is a species of flowering plant in the mallow family, Malvaceae, that is endemic to the Hawaiian Islands.

This plant is celebrated for its stunning, bright red flowers that make it a coveted addition to gardens and natural landscapes in Hawaii and other parts of the world.

Native specifically to the islands of Oahu and Kauai, Hibiscus kokio is considered rare due to its limited geographic range and the threats it faces from habitat loss, invasive species, and other environmental challenges.

The plant typically manifests as a small tree or shrub, reaching up to 10 feet in height, with glossy green leaves that have a slightly toothed margin.

Its most notable characteristic is the large, vibrant red flowers, each spanning up to 4 inches in diameter, showcasing the classic hibiscus shape with five petals and a prominent staminal column.

Hibiscus kokio’s flowering season extends throughout the year, with a peak in the warmer months, contributing not only to its ornamental value but also to the ecological balance of its native environments, underscoring the significance of preserving and propagating this species to maintain the biodiversity and cultural heritage of the Hawaiian Islands.
