Hibiscus richardsonii is an annual to short-lived perennial herb that is nationally critically endangered in the wild. It grows up to 1 m tall.
It is indigenous to New Zealand’s North Island and is found in isolated pockets from Te Paki eastward to Hicks Bay, including Great Barrier and Mayor (Tuhua) Islands. It is also native to eastern Australia in New South Wales.
Its habitat is strictly coastal and grows in recently disturbed habitats, such as around slip scars, within petrel colonies, on talus slopes and under open coastal scrub and forest.
It produces develops solitary translucent pods which open during October – May to display a cream hibiscus flower. The flower later droops and the pod becomes a seed capsule. The seed is long-lived and plants often appear following major habitat disturbances caused by storm damage or fire.
It is very palatable to stock and is prone to be outcompeted by faster growing and taller weeds. As a species requiring open ground, it is especially vulnerable to this threat.
