Ligustrum lucidum - tree privet

Small to medium, hardy, fast-growing, evergreen, round-headed tree up to 10 m tall, sometimes a dense shrub. Leaves oval-shaped, glossy on the upper surface. Flowers white, very sweet-smelling.

  • Flowers White, about 6 mm in diameter, with four sharply bent back lobes at the end of the corolla tube, and yellow anthers. Flowers strongly-scented, in broadly pyramid-shaped panicles 25 x 20 cm. Flowers Nov-Mar.
  • Fruit Elliptical-oblong berry-like drupes, 6 x 5 mm, bluish or purplish-black, coated with powdery bloom.
  • Leaves Dark green, large, glossy on the upper surface, oval to elliptical, 5-13 cm long by 3-6 cm wide. Leaf stalks 1-2 cm long.
  • Stems Hairless shoots.

Habitat

Gardens, forest margins, coastal cliffs and waste places.

Distribution

NI only, common in North Auckland, Auckland and coastal Bay of Plenty. Originally from China.

Comments

Leaves and fruit poisonous. Widely believed to contribute to allergies and asthma, although since the plant is insect-pollinated, it does not produce any wind-blown pollen. Commonly used as an urban hedge plant in warmer parts of the country. Listed on the National Pest Plant Accord (see Introduction for details).

Derivation of botanical name

Ligustrum (Lat.) = privet; lucidum (Lat.) = shining, referring to the glossy leaves.
