Unlike other members of the genus Ailanthus , it is found in temperate climates rather than the tropics. The tree grows rapidly, and is capable of reaching heights of 15 metres 49 ft in 25 years.
While the species rarely lives more than 50 years, some specimens exceed years of age. The twigs are stout, smooth to lightly pubescent, and reddish or chestnut in color. They have lenticels and heart-shaped leaf scars i. The buds are finely pubescent, dome-shaped, and partially hidden behind the petiole , though they are completely visible in the dormant season at the sinuses of the leaf scars.
The ends of the branches become pendulous. All parts of the plant have a distinguishing strong odor that is often likened to peanuts, cashews,  or rotting cashews. The leaves are large, odd- or even- pinnately compound on the stem. They range in size from 30 to 90 centimetres 1 to 3 ft in length and contain 10—41 leaflets organised in pairs, with the largest leaves found on vigorous young sprouts. When they emerge in the spring, the leaves are bronze, then quickly turn from medium to dark green as they grow.
The leaflets are ovate-lanceolate with entire margins, somewhat asymmetric and occasionally not directly opposite to each other. Each leaflet is 5—18 cm 2—7 in long and 2. They have a long, tapering end, while the bases have two to four teeth, each containing one or more glands at the tip. The petioles are 5—12 millimetres 0. The flowers are small and appear in large panicles up to 50 cm 20 in in length at the end of new shoots. The individual flowers are yellowish green to reddish in color, each with five petals and sepals.
Male trees produce three to four times as many flowers as the females, making the male flowers more conspicuous. Furthermore, the male plants emit a foul-smelling odor while flowering to attract pollinating insects.
Female flowers contain 10 or rarely five through abortion sterile stamens stamenoids with heart-shaped anthers. The pistil is made up of five free carpels i. Their styles are united and slender with star-shaped stigmata. The samara is large and twisted at the tips, making it spin as it falls, assisting wind dispersal,   and aiding buoyancy for long-distance dispersal through hydrochory.
In China, the tree of heaven has a long and rich history. It was mentioned in the oldest extant Chinese dictionary and listed in many Chinese medical texts for its purported curative ability. The roots, leaves, and bark are used in traditional Chinese medicine , primarily as an astringent. The tree has been grown extensively both in China and abroad as a host plant for the ailanthus silkmoth , a moth involved in silk production. The tree was first brought from China to Europe in the s and to the United States inIt was one of the first trees brought west during a time when chinoiserie was dominating European arts and was initially hailed as a beautiful garden specimen.
However, enthusiasm soon waned after gardeners became familiar with its suckering habits and its foul odor. Despite this, it was used extensively as a street tree during much of the 19th century. Outside Europe and the United States, the plant has been spread to many other areas beyond its native range, and is considered internationally as a noxious weed.
This has led to the tree being called "tree of hell" among gardeners and conservationists. The first scientific descriptions of the tree of heaven were made shortly after it was introduced to Europe by French Jesuit Pierre Nicholas d'Incarville , who had sent seeds from Peking via Siberia to his botanist friend Bernard de Jussieu in the s. The seeds sent by d'Incarville were thought to be from the economically important and similar looking Chinese varnish tree Toxicodendron vernicifluum , which he had observed in the lower Yangtze region, rather than the tree of heaven.
D'Incarville attached a note indicating this, which caused much taxonomic confusion over the next few decades. Webb, the owner of an exotic plant garden in Busbridge , England. Confusion in naming began when the tree was described by all three men with three different names.
In Paris, Linnaeus gave the plant the name Rhus succedanea , while it was known commonly as grand vernis du Japon. In London, the specimens were named by Miller as Toxicodendron altissima , and in Busbridge, it was dubbed in the old classification system as Rhus Sinese foliis alatis.
Records exist from the s of disputes over the proper name between Philip Miller and John Ellis, curator of Webb's garden in Busbridge. Rather than the issue being resolved, more names soon appeared for the plant: Jakob Friedrich Ehrhart observed a specimen in Utrecht in and named it Rhus cacodendron. He published an article with an illustrated description and gave it the name Ailanthus glandulosa , placing it in the same genus as the tropical species then known as A.
The name is derived from the Ambonese word ailanto , meaning "heaven-tree" or "tree reaching for the sky". He decided to transfer Miller's older specific name into the genus of Desfontaines, resulting in the accepted name Ailanthus altissima. The plant is sometimes incorrectly cited with the specific epithet in the masculine glandulosus or altissimus , which is incorrect since botanical, like Classical Latin , treats most tree names as feminine.
The three varieties of A. Ailanthus altissima is native to northern and central China,  Taiwan  and northern Korea. The tree prefers moist and loamy soils but is adaptable to a very wide range of soil conditions and pH values. It is drought-hardy, but not tolerant of flooding. It also does not tolerate deep shade. The earliest introductions of A. The tree may be native to these areas, but the tree is generally agreed to be a very early introduction.
In , not long after Jussieu had sent seeds to England, some were forwarded to the United States by William Hamilton , a gardener in Philadelphia. In both Europe and America, it quickly became a favoured ornamental, especially as a street tree, and by , it was available in most nurseries. It has escaped cultivation in all areas where it was introduced, but most extensively in the United States. In North America, A. In the west, it is found from New Mexico west to California and north to Washington.
For example, a study in North Carolina found the tree of heaven was present on 1. For this reason, control measures on public lands  and private property  are advised where A. Tree of heaven is an opportunistic plant that thrives in full sun and disturbed areas.
It spreads aggressively both by seeds and vegetatively by root sprouts , re-sprouting rapidly after being cut. The same study characterised the tree as using a "gap-obligate" strategy to reach the forest canopy , meaning it grows rapidly during a very short period rather than growing slowly over a long period.
It can withstand cement dust and fumes from coal tar operations, as well as resist ozone exposure relatively well. Furthermore, high concentrations of mercury have been found built up in tissues of the plant. Ailanthus has been used to re-vegetate areas where acid mine drainage has occurred and it has been shown to tolerate pH levels as low as 4. It can withstand very low phosphorus levels and high salinity levels. The drought-tolerance of the tree is strong due to its ability to effectively store water in its root system.
The roots are also aggressive enough to cause damage to subterranean sewers and pipes. Ailanthus produces an allelopathic chemical called ailanthone , which inhibits the growth of other plants. The same study tested the extract as an herbicide on garden cress, redroot pigweed Amaranthus retroflexus , velvetleaf Abutilon theophrasti , yellow bristlegrass Setaria pumila , barnyard grass Echinochloa crusgalli , pea Pisum sativum cv.
Sugar Snap and maize Zea mays cv. Silver Queen. Populations without prior exposure to the chemicals are most susceptible to them. Seeds produced from exposed plants have also been shown to be more resistant than their unexposed counterparts. The tree of heaven is a very rapidly growing tree, possibly the fastest growing tree in North America. Shade considerably hampers growth rates.
Older trees, while growing much slower, still do so faster than other trees. Studies found that Californian trees grew faster than their East Coast counterparts, and American trees in general grew faster than Chinese ones.
In northern Europe the tree of heaven was not considered naturalised in cities until after the Second World War. This has been attributed to the tree's ability to colonize areas of rubble of destroyed buildings where most other plants would not grow. It has colonized natural areas in Hungary , for example, and is considered a threat to biodiversity at that country's Aggtelek National Park.
Several species of Lepidoptera use the leaves of Ailanthus as food, including the Indian moon moth Actias selene and the common grass yellow Eurema hecabe. In North America the tree is the host plant for the ailanthus webworm Atteva aurea , though this ermine moth is native to Central and South America and originally used other members of the mostly tropical Simaroubaceae as its hosts.
In North America, the leaves of ailanthus are sometimes attacked by Aculops ailanthii , a mite in the family Eriophyidae. Leaves infested by the mite begin to curl and become glossy, reducing their ability to function. Therefore, this species has been proposed as a possible biocontrol for ailanthus in the Americas.
Due to the tree of heaven's weedy habit, landowners and other organisations often resort to various methods of control to keep its populations in check. For example, the city of Basel in Switzerland has an eradication program for the tree. Means of eradication can be physical, thermal, managerial, biological or chemical. A combination of several of these can be most effective, though they must of course be compatible.
All have some positive and negative aspects, but the most effective regimen is generally a mixture of chemical and physical control. It involves the application of foliar or basal herbicides to kill existing trees, while either hand pulling or mowing seedlings to prevent new growth. In addition to its use as an ornamental plant, the tree of heaven is also used for its wood and as a host plant to feed silkworms of the moth Samia cynthia , which produces silk that is stronger and cheaper than mulberry silk, although with inferior gloss and texture.
This type of silk is known under various names: " pongee ", " eri silk " and " Shantung silk ", the last name being derived from Shandong in China where this silk is often produced. Its production is particularly well known in the Yantai region of that province.
The moth has also been introduced in the United States. The pale yellow, close-grained and satiny wood of ailanthus has been used in cabinet work. Zhejiang in eastern China is most famous for producing these steamers.
