General Notes

hia is a culturally important, endemic Hawaiian tree that dominates native forests, and is the most abundant native tree, especially on the Big Island and Kaua'i. It occupies a variety of habitats and grows from a tall emergent rainforest tree to a short, prostrate shrub. It has leathery leaves that are often felty white on the undersides, and rough trunk covered in flaky, fissured bark. Their bright red flowers are laced with nectar and are an important food source for native Hawaiian birds. A fungal disease called rapid hia death has been found on Hawai'i, Kaua'i, Maui, and Oahu (https://cms.ctahr.hawaii.edu/rod/). The disease is comprised of two pathogens, Ceratocystis lukuohia and Ceratocystis huliohiaMetrosideros polymorpha has no HPWRA (Hawai'i Pacific Weed Risk Assessment) score, and the Plant Pono link is: https://plantpono.org/pono-plants/metrosideros-polymorpha/
