Clay's Hibiscus

Clay's Hibiscus, Hibiscus clayi, is a rare flowering shrub in the family Malvaceae endemic to the island of Kauai in the Hawaiian archipelago. It is one of the native Hawaiian hibiscus species belonging to the kokio group, characterized by brilliantly colored flowers adapted to pollination by native Hawaiian honeycreepers, which probe the tubular flowers for nectar. Hibiscus clayi produces large, vivid red to orange-red flowers with five overlapping petals surrounding a prominent staminal column, typical of the hibiscus form. The shrub grows in dry to mesic forest habitats at low to moderate elevations on Kauai, where it is associated with native Hawaiian dryland forest communities. Like many Hawaiian plants, Clay's Hibiscus evolved in near-total isolation and is adapted to a unique ecological community that has been severely disrupted by the introduction of non-native species, habitat conversion, and the decline of native pollinators. The species is critically threatened by habitat loss, competition from invasive plants, and the extinction of native Hawaiian honeycreeper pollinators due to introduced avian malaria. Hibiscus clayi is listed as Endangered and is the subject of conservation efforts including propagation in botanical gardens and habitat restoration projects on Kauai.
