Pittosporum eugenioides aka Lemonwood

Pittosporum eugenioides is an evergreen tree or large shrub from New Zealand. It belongs to the Pittosporaceae family. Its common names include lemonwood, tarata, and New Zealand hedge laurel. It grows on both the North and South Islands. Its wild habitats include lowland forests and forests at higher elevations. Kew places it within the subtropical climate zone.

In gardens, it forms a large, bushy plant with upright growth. The RHS gives a height range of 13–26 feet [4–8 metres]. Its spread reaches about 8–13 feet [2.5–4 metres]. Plants take around 10–20 years to reach their full size. Slender, dark shoots carry glossy, oval leaves of light green. The leaves stay on the plant through winter. Small flowers form clusters in summer. Their pale yellow colour contrasts with the foliage. The flowers also have a scent.

Grow this species in full sun with shelter from cold, drying winds. A south-facing or west-facing site suits the RHS guidance. It accepts chalk, loam, and sandy soils with good drainage. Acid, neutral, and alkaline soil reactions all suit it. Moist soil suits its growth, but it also tolerates drought. The RHS rates its UK hardiness as H4. This covers minimum temperatures around 14–23°F [-10 to -5°C]. PFAF lists USDA zones 8–11. Remove growth damaged by frost in spring.

Its evergreen form suits hedges, screens, and structural planting. The RHS also suggests courtyards, coastal gardens, and informal borders. Gravel gardens and gardens with Mediterranean climates offer other settings. PFAF lists sunny woodland edges and sites with dappled shade. The RHS includes it among plants for low-maintenance schemes. Take semi-ripe cuttings from the current season's growth to raise new plants. Roots take about 8–12 weeks to form at 54–68°F [12–20°C].

Possible pests include aphids, cushion scale, and pittosporum sucker. Glasshouse red spider mites may also attack it. Powdery mildew and leaf spot can occur. Honey fungus is a less frequent problem. PFAF records bark resin as a chewing gum. It also lists uses in hair oil and pot-pourri. A reported medicinal use addresses bad breath. These uses do not establish that all parts are edible. The supplied evidence does not establish this species' toxicity.
