Wild privet, also sometimes known as common privet or European privet ( Ligustrum vulgare )

A privet is a flowering plant in the genus Ligustrum. The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, [1] native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species, Ligustrum australianum, [2] extends as a native into Queensland. [3] Some species have become widely naturalized or invasive where introduced. Privet was originally the name for the European semi-evergreen shrub Ligustrum vulgare , and later also for the more reliably evergreen Ligustrum ovalifolium and its hybrid Ligustrum × ibolium used extensively for privacy hedging, though now the name is applied to all members of the genus. [4] The generic name was applied by Pliny the Elder (23–79 AD) to L. vulgare. [5] It is often suggested that the name privet is related to private, but the OED states that there is no evidence to support this. [6]

Description

Privet is a group of shrubs and small trees of southern and eastern Asia, from the Himalayas extending into Australia. They may be evergreen or deciduous, and are tolerant of different soil types. They often have conspicuous heads of white flowers [7] followed by black berries.

Uses and cultivation

In addition to being cultivated to create ornamental hedges and foliage, privet is also widely used in horticulture and flower arrangements. [8] The oval leaf privet Ligustrum ovalifolium is used for hedges, while its flexible twigs are sometimes used as cords for lashing. [8] The tree species, especially Chinese privet is frequently used as a street tree in Europe, while other species including Ligustrum japonicum and Ligustrum quihoui are among the others also sometimes used as ornamental plants in gardens. [9] Privet became very popular in Britain as a replacement for ornamental railings around properties, which had been lost to the 1941 Government compulsorily requisitioning of all post-1850 iron gates and railings for the war effort [10] the idea being that the donated metal would be melted down for use in the manufacture of armaments in WWII, although this ultimately did not happen. [11] The remaining stubs of sawn-off railings can still be seen on many garden walls in the UK, often partly obscured by privet bushes.

Chinese privet is used in traditional herbal medicine. [12] The decoction of privet leaves or bark helps to treat diarrhea, stomach ulcers, chronic bowel problems, chapped lips, sore mouths and throats, and a wash for skin problems. [12] Privet leaves and bark have bitter properties that make a useful tea for improving appetite and digestion in chemotherapy patients. [12] Kuding is a Chinese tea made from either a Ligustrum or Ilex species.

Some species produce a fruit, which is mildly toxic to humans. [8] [13] Symptoms from eating privet fruit include nausea, headache, abdominal pain, vomiting, diarrhea, weakness, low blood pressure, and low body temperature. [8] At least some privet species are known to be toxic to horses. [14]

Ecology

A plant may produce thousands of fruits, most of which are eaten by birds. Privet is used as a food plant by the larvae of some Lepidoptera species including the common emerald, common marbled carpet, copper underwing, engrailed, mottled beauty, scalloped hazel, small angle shades, v-pug, privet hawk moth and willow beauty.

Invasiveness

Privet is a successful invasive species because of its ability to outcompete and therefore displace native vegetation, due to its adaptability. Various species are now a problem in North America, Australia and New Zealand.

Selected species

The Integrated Taxonomic Information System lists eleven "accepted" species of Ligustrum. [15] Additional species are listed in other references. [16] [17] [18]

<span class="mw-page-title-main">Oleaceae</span> Family of flowering plants

Oleaceae, also known as the olive family or sometimes the lilac family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales. It presently comprises 28 genera, one of which is recently extinct. The extant genera include Cartrema, which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.

<span class="mw-page-title-main">Laurel forest</span> Type of subtropical forest

Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures. The forest is characterized by broadleaf tree species with evergreen, glossy and elongated leaves, known as "laurophyll" or "lauroid". Plants from the laurel family (Lauraceae) may or may not be present, depending on the location.

<i>Aucuba</i> Genus of flowering plants

Aucuba is a genus of three to ten species of flowering plants, now placed in the family Garryaceae, although formerly classified in the Aucubaceae or Cornaceae.

<i>Symplocos</i> Genus of flowering plants

Symplocos is a genus of flowering plants in the order Ericales. It contains about 300 species distributed in Asia and the Americas. Many species grow in humid tropical regions. This is sometimes considered to be the only genus in family Symplocaceae. Plants in this family are shrubs and trees with white or yellow flowers. The oldest fossils of the genus date to the lower Eocene of Europe and North America, with the genus being present in Europe as late as the Pliocene. Fossil seeds of †Symplocos granulosa are frequent in sediment rock layers of the Late Oligocene to the Late Miocene of Denmark, Germany, Austria and Poland. The fossil seeds are very similar to the seeds of the extan southern Chinese species Symplocos glandulifera and Symplocos sulcata. Fossil seeds of †Symplocos paucicostata are known from the Middle Pliocene sediment rock layers in Reuver, the Netherlands and from the Late Pliocene sediment rock layers in northern Italy. The fossil seeds are very similar to the seeds of the extant East Asian species Symplocos paniculata
