    HVH: "'Hibiscus arnottianus' is one of the original species hibiscus. Native to Hawaii, it is the only ancestor of the modern hibiscus with a light fragrance, although it releases its fragrance quickly after the bloom opens. H. arnottianus blooms with mini 3-5" pure white single blooms.

    The bush is very slow growing and grows to medium height. Released from HVH in 2009."

    According to the University of Hawaii, Hibiscus arnottianus is a shrub or small tree that grows generally 15 to 20 feet in height although occasionally to 30 feet tall. Tall specimens can be up to 20 feet in diameter. Individual plants vary in appearance from open and airy to compact. The leaves are oval with a smooth upper surface and smooth or slightly toothed edges. Leaves are 4 to 6 inches long and often have red veins and stems.

    The single white flowers are pinwheel shaped, up to 4 inches across, borne at the ends of the branches. The staminal column is pink to red (except in subspecies 'immaculatus' which has a white column). The flowers may be slightly pink or may age to pale pink, and are slightly fragrant. In cultivation, Hibiscus arnottianus blooms almost continuously.

    Three subspecies are recognized.

    H. arnottianus blooms heavily, and the flowers sometimes have a faint, pleasant scent. This hibiscus is tougher and faster growing than the fancy large-flowered hybrids, but slower than some of the other species. Remarkably tolerant of temperatures down to freezing for short periods. Well-suited to growing in a container, but I would recommend 5 gallons+.
