Ralphs Karo

Pittosporum ralphii is a hardy, evergreen native shrub or small tree ideal for hedging, screening, and native planting projects across New Zealand. Known for its narrow, grey-green leaves and upright form, it typically grows to 4–6 metres tall and 3–4 metres wide. The foliage has a subtle silver tone, which softens the appearance of dense planting and adds contrast to green-dominated gardens. In spring, small dark red to purple flowers appear, offering seasonal interest and attracting native insects.
