Privet was originally the name for the European semi-evergreen shrub Ligustrum vulgare, and later also for the more reliably evergreen Ligustrum ovalifolium (Japanese privet), used extensively for privacy hedging (hence "privet", private). The term is now used for all members of the genus Ligustrum, which includes about 40-50 species of evergreen, semi-evergreen or deciduous shrubs and small trees, native to Europe, north Africa, Asia and Australasia, with the centre of diversity in China, the Himalaya, Japan and Taiwan. They are placed in the olive family Oleaceae.
The flowers are small and fragrant and borne in panicles. They have four curled-back petals and two high stamens with yellow or red anthers, between which is the low pistil; the petals and stamens fall off after the flower is fertilized, leaving the pistil in the calyx tube. Flowering starts after 330 growing degree days. The fruits, borne in clusters, are small purple to black drupes, poisonous for humans but readily eaten by many birds. In favorable growing conditions, individual shrubs may produce thousands of fruits. Privet is used as a food plant by the larvae of some Lepidoptera species including Common Emerald, Common Marbled Carpet, Copper Underwing, The Engrailed, Mottled Beauty, Scalloped Hazel, Small Angle Shades, The V-pug and Willow Beauty.

[edit] Problems
Privet is one of several plants which are poisonous to horses. In the some parts of the world where they are not native, some privet species have become invasive weeds, spreading into wilderness areas and displacing native species. This is particularly a problem in North America, where no species of the genus occurs naturally.[4] Privet is a huge problem in New Zealand. It is banned from sale or cultivation in New Zealand due to the effects of its pollen on asthma sufferers. Privet pollen is known to cause asthma and eczema in sufferers. Privet can be removed by contacting the local government to report its presence.[citation needed]
