About

Olearia macrodonta (mountain holly or arorangi in New Zealand, or New Zealand holly elsewhere) is a small sub-alpine evergreen tree endemic to New Zealand, from the plant family Asteraceae. It is closely related to the narrow-leaved Olearia ilicifolia, with which it shares several characteristics including largely undulating and serrated grey-green leaves. These common characteristics mean the two species are often confused with one another. It is found in lowland to sub-alpine forests from the East Cape of the North Island of New Zealand southwards throughout the South Island and Stewart Island, at 450–1,200 metres (1,480–3,940 ft) in altitude. It grows to around 2.5-4 metres tall and 2.5-4 metres wide, carrying evergreen foliage. Grow it in full sun and most soil types. It tolerates soil of any pH, well-drained conditions and south-facing, north-facing, west-facing and east-facing aspects.
