In 1751, Jussieu planted a few seeds in France and sent others on to Philip Miller, the superintendent at the Chelsea Physic Garden, and to Philip C. Webb, the owner of an exotic plant garden in Busbridge, England. Deciduous; On invasive species list; Height of over 70′ Very fast growing; Leaves are pinnately compound; Has a strong, unpleasant odor; Is most common in urban and disturbed areas Because the trees exhibit rapid growth for the first few years, the trunk has uneven texture between the inner and outer wood, which can cause the wood to twist or crack during drying. Zhejiang Province in eastern China is most famous for producing these steamers. D'Incarville had sent seeds from Peking via Siberia to his botanist friend Bernard de Jussieu in the 1740s. [1] In many countries, it is an invasive species due to its ability both to colonize disturbed areas quickly and to suppress competition with allelopathic chemicals. "[64] The leaves are large, odd- or even-pinnately compound on the stem. Flowers Species is dioecious (separate male and female plants) and flowering occurs in early summer when large clusters of small yellow flowers on 20 inch long stems develop above the foliage. Upon the barred and slitted wall the splotched shadow of the heaven-tree shuddered and pulsed monstrously in scarce any wind; rich and sad, the singing fell behind.[65]. Scientific Name; AIGL: Ailanthus glandulosa Desf. When they emerge in the spring, the leaves are bronze then quickly turn from medium to dark green as they grow. People living near the lower Yellow River know it by the name chunshu (simplified Chinese: 椿树; traditional Chinese: 椿樹; pinyin: chūnshù), meaning "spring tree". Within the oldest extant Chinese dictionary, the Erya, written in the 3rd century BC, the tree of heaven is mentioned second among a list of trees. The moth has also been introduced in the United States. They range in size from 30 to 90 cm (1 to 3 feet) in length and contain 10–41 leaflets organised in pairs, with the largest leaves found on vigorous young sprouts. currently features 3816 plants and 23,855 images. [45], Ailanthus produces an allelopathic chemical called ailanthone, which inhibits the growth of other plants. Within the oldest extant Chinese dictionary, the Erya, written in the 3rd century BC, the tree of heaven is mentioned second among a list of trees. One study showed that a crude extract of the root bark inhibited 50% of a sample of garden cress (Lepidium sativum) seeds from germinating. Furthermore, the male plants emit a foul-smelling odor while flowering to attract pollinating insects. Common Name: Tree of Heaven. The flowers are small, yello… It 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. [1] Prolonged cold and snow cover cause dieback, although the trees resprout from the roots. [24] In Montenegro[28] and Albania[29][30] A. altissima is widespread in both rural and urban areas and while in the first it was introduced as an ornamental plant, it very soon invaded native ecosystems with disastrous results and became an invasive species. Ailanthus altissima Common name(s): Tree-of-Heaven The Tree-of-Heaven is native to northern China where it has a rich history dating back hundreds of years. Each work favoured a different character, however, and there is still some debate in the Chinese botanical community as to which character should be used. The ends of the branches become pendulous. Ailanthus altissima Other common names: Chinese Sumac, Tree of Heaven Other scientific names: Ailanthus glandulosus, Ailanthus peregrina, Toxicodendron altissimum [6] The seeds borne on the female trees are 5 mm in diameter and each is encapsulated in a samara that is 2.5 cm (0.98 in) long and 1 cm (0.39 in) broad, appearing July though August, but can persist on the tree until the next spring. A combination of several of these can be most effective, though they must of course be compatible. Ailanthus glandulosus Desf. This small, very colorful moth resembles a true bug or beetle when not in flight, but in flight it resembles a wasp. Tree of heaven Tree-of-heaven, commonly referred to as Ailanthus altissima, is a rapidly growing deciduous tree native to a region extending from northern and central China, Taiwan and northern Korea to Australia. Ailanthus rhodoptera F. Muell. Higher numbers represent more temperate areas. This manifests itself occasionally when expressing best wishes to a friend's father and mother in a letter, where one can write "wishing your ailanthus and daylily are strong and happy", with ailanthus metaphorically referring to the father and daylily to the mother. The petioles are 5–12 mm (0.2-0.5 inch) long. Swingle Tree of Heaven. This fast growing tree can reach 80 feet in its relatively short life (50 years). Unlike other members of the genus Ailanthus, it is found in temperate climates rather than the tropics. Techniques have been developed for drying the wood so as to prevent this cracking, allowing it to be commercially harvested. It has now naturalized throughout much of the United States. In both Europe and America it quickly became a favoured ornamental, especially as a street tree, and by 1840 it was available in most nurseries. Each work favoured a different character, however, and there is still some debate in the Chinese botanical commun… Follow us on social media to keep up-to-date. [39] Growth of one to two metres (3.5-6.5 ft) per year for the first four years is considered normal. Leaves infested by the mite begin to curl and become glossy, reducing their ability to function. Scientific Name: Ailanthus altissima Common Name: Tree of heaven Growing Zone: USA: 5 to 8 Life Cycle / Plant Type: Tree Plant Details. takanai. Its production is particularly well known in the Yantai region of that province. Seeds produced from exposed plants have also been shown to be more resistant than their unexposed counterparts. they meet at the edges without overlapping), white and hairy towards the inside. For this reason, control measures on public lands[41] and private property[42] are advised where A. altissima has naturalized. [8], Confusion in naming began when the tree was described by all three men with three different names. Mature trees … Common Name: tree of heaven, Ailanthus, Chinese sumac, stinking sumac Family Name: Simaroubaceae - Quassia family Native Range: Eastern Asia NJ Status: Widespread and highly threatening to native plant communities. Ailanthus altissima Common name(s): Tree-of-Heaven The Tree-of-Heaven is native to northern China where it has a rich history dating back hundreds of years. (ailanthus) genus and Simaroubaceae (Quassia family). A large polygamous tree, upto 30 m high or more. It is drought-hardy, but not tolerant of flooding. The plant belongs to Ailanthus Desf. [23] It has naturalized across much of Europe, including Germany,[27] Austria, Switzerland, the Czech Republic, the Pannonian region (i.e. Silver Queen). [8] It is also considered a good source of firewood across much of its range as it is moderately hard and heavy, yet readily available. [7], The earliest introductions of A. altissima to countries outside of its native range were to the southern areas of Korea and to Japan. [20] It was once very popular in cultivation in both Europe and North America, but this popularity dropped, especially in the United States, due to the disagreeable odor of its blossoms and the weediness of its habit. The problem of odor was previously avoided by only selling pistillate plants since only males produce the smell, but a higher seed production also results. [1] The tree also resprouts vigorously when cut, making its eradication difficult and time-consuming. [22] In China it is native to every province except Gansu, Heilongjiang, Hainan, Jilin, Ningxia, Qinghai, Xinjiang, and Tibet. Later scholars associated this tree with ailanthus and applied the metaphor to children who, like stump sprouts of the tree, will not develop into a worthwhile human being if they don't follow rules or traditions.[62]. It has smooth stems with pale gray bark, and twigs which are light chestnut brown, especially in the dormant season. D'Incarville attached a note indicating this, which caused much taxonomic confusion over the next few decades. In the 2013 book Teardown: Memoir of a Vanishing City by journalist Gordon Young, the tree is referenced in a description of the Carriage Town neighborhood in Flint, Michigan. This has been attributed to the tree's ability to colonize areas of rubble of destroyed buildings where most other plants would not grow. Rather than the issue being resolved, more names soon appeared for the plant: Jakob Friedrich Ehrhart observed a specimen in Utrecht in 1782 and named it Rhus cacodendron.[8]. The name is in reference to the great heights of the tree (helped by a very robust grow rate). 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. Deciduous trees, up to 25 m tall; bark smooth and straightly grained; branches with pith, yellow or yellow-brown pubescent when young. Return to our Trees of Canada resource here: In addition to the tree of heaven's various uses, it has also been a part of Chinese culture for many centuries and has more recently attained a similar status in the west. Other Common Names: stinking quassia, copal-tree Weed class: C Year Listed: 2012 Native to: China and Taiwan Is this Weed Toxic? Life Cycle. Common Name: tree-of-Heaven, tree-that-grows-in-Brooklyn. [14] Primary wind dispersal and secondary water dispersal are usually positively correlated in A. altissima since most morphological characteristics of samaras affect both dispersal modes in the same way – except for the width of the samaras, which in contrast affects both types of dispersal in opposing ways, allowing differentiation in the dispersal strategies of this tree. [58] In Germany the tree is commonly planted in gardens. Common Name(s): Ailanthus; Chinese sumac; Copal Tree; Paradise-tree; Stinking shumac; Tree of Heaven; Tree-of-Heaven; Varnish tree A tincture of the root bark was thought useful by American herbalists in the 19th century. Swingle ( ITIS) Common Name: Tree-of-heaven, China-sumac, varnishtree. [37][38] It is classified as a noxious or invasive plant on National Forest System lands and in many states[39] because its prolific seed production, high germination rates and capacity to regrow from roots and root fragments enable A. altissima[40] to out-compete native species. [46] The inhibitors are strongest in the bark and roots, but are also present in the leaves, wood and seeds of the plant. [8], The pale yellow, close-grained and satiny wood of ailanthus has been used in cabinet work. [11] The rachis is light to reddish-green with a swollen base. introduced perennial tree, reproducing by seed and root suckers. The samara is large and twisted at the tips, making it spin as it falls, assisting wind dispersal,[7][9] and aiding buoyancy for long-distance dispersal through hydrochory. It was formerly known under the scientific name Atteva punctella (see Taxonomy section). It would be considered beautiful except that there are too many of it. The tree is associated with the black prisoner's despair in the face of his impending execution and the spirituals that he sings in chorus with other black people who keep a sort of vigil in the street below: ...they sang spirituals while white people slowed and stopped in the leafed darkness that was almost summer, to listen to those who were sure to die and him who was already dead singing about heaven and being tired; or perhaps in the interval between songs a rich, sourceless voice coming out of the high darkness where the ragged shadow of the heaven-tree which snooded the street lamp at the corner fretted and mourned: "Fo days mo! Native of China, introduced into North America in 1784 as an ornamental. The roots are also aggressive enough to cause damage to subterranean sewers and pipes. [35] Similarly, another study conducted in southwestern Virginia determined that the tree of heaven is thriving along approximately 30% of the state's interstate highway system length or mileage. It was mentioned again in a materia medica compiled during the Tang dynastyin 656 AD. The museum hired the Detroit Tree of Heaven Woodshop, an artists' collective, to use the wood to create benches, sculptures and other amenities in and around the building. [8] Along highways, it often forms dense thickets in which few other tree species are present, largely due to the toxins it produces to prevent competition. At that time as well as now, ailanthus was common in neglected urban areas. [66], Ailanthus is also sometimes counter-nicknamed "tree from hell" due to its prolific invasiveness and the difficulty in eradicating it. After stopping and taking photos of this unknown (to me) plant, I was able to identify it as Tree-of-Heaven (Ailanthus altissima). A fast growing deciduous tree from China can grow 20m or more. [39], In northern Europe the tree of heaven was not considered naturalised in cities until after the Second World War. The tree is commonly called tree of heaven—from the Ambonese word aylanto (rendered ailanthus in Latin). Also a Latin superlative meaning very high or tallest; altissima: from alta, high. The flowers are small and appear in large panicles up to 50 cm (20 in) in length at the end of new shoots. [8][12][13] They appear from mid-April in the south of its range to July in the north. “A medium to large tree to 25 m tall. There are three varieties of A. altissima: A. altissima is native to northern and central China,[1] Taiwan[23] and northern Korea. It has colonized natural areas in Hungary, for example, and is considered a threat to biodiversity at that country's Aggtelek National Park. Ailanthus altissima, commonly called tree of heaven, is native to China and was introduced into New York City in 1820 as a street tree and food source for silkworm caterpillars. It was mentioned in the oldest extant Chinese dictionary and listed in many Chinese medical texts for its purported curative ability. Ailanthus altissima (Mill.) [8] These are virtually found anywhere in the U.S., but especially in arid regions bordering the Great Plains, very wet regions in the southern Appalachians, cold areas of the lower Rocky Mountains and throughout much of the California Central Valley, forming dense thickets that displace native plants. It becomes rare in the north, occurring only infrequently in southern Scotland. 2-10 mm long; petiole ca. Latin name: Ailanthus altissima Common name: Tree of Heaven. The Linked Data Service provides access to commonly found standards and vocabularies promulgated by the Library of Congress. [16] Michael Dirr, a noted American horticulturalist and professor at the University of Georgia, reported meeting, in 1982, a grower who could not find any buyers. U.S. Forest Service Fire Effects Information System: National Invasive Species Information Center: species profile of, United States National Agricultural Library, National Park Service, Plant Conservation Alliance, Alien Plant Working Group: Tree of Heaven (, Cal-IPC/California Invasive Plant Council: plant profile of,, Short description is different from Wikidata, Articles containing Chinese-language text, Articles containing simplified Chinese-language text, Articles containing traditional Chinese-language text, Taxonbars with automatically added basionyms, Creative Commons Attribution-ShareAlike License, This page was last edited on 24 November 2020, at 23:54. [61], In addition to the tree of heaven's various uses, it has also been a part of Chinese culture for many centuries and has more recently attained a similar status in the west. Most leaflets have one to three coarse teeth near their base. It also does not tolerate deep shade. Although the live tree tends to have very flexible wood, the wood is quite hard once properly dried. It spreads aggressively both by seeds and vegetatively by root sprouts, re-sprouting rapidly after being cut. In Paris, Linnaeus gave the plant the name Rhus succedanea, while it was known commonly as grand vernis du Japon. [49], The tree of heaven is a very rapidly growing tree, possibly the fastest growing tree in North America. Populations without prior exposure to the chemicals are most susceptible to them. Festive Victorian-era homes in various stages of restoration battled for supremacy with boarded-up firetraps and overgrown lots landscaped with weeds, garbage, and “ghetto palms,” a particularly hardy invasive species known more formally as Ailanthus altissima, or the tree of heaven, perhaps because only God can kill the things. It grows in boarded up lots and out of neglected rubbish heaps. [51], Due to the tree of heaven's weedy habit, landowners and other organisations often resort to various methods of control in order to keep its populations in check. [27] The tree has furthermore become unpopular in cultivation in the west because it is short-lived and that the trunk soon becomes hollow, making trees more than two feet in diameter unstable in high winds.[53]. Hardiness zones are based largely on climate, particularly minimum temperatures. Some people call it the Tree of Heaven. [1][7] It is considered a shade-intolerant tree and cannot compete in low-light situations,[43] though it is sometimes found competing with hardwoods, but such competition rather indicates it was present at the time the stand was established. [8] The leaflets' upper sides are dark green in color with light green veins, while the undersides are a more whitish green. "[I]n a sense, the sculpture garden was designed around the tree", said a former aide to Noguchi, Bonnie Rychlak, who later became the museum curator. Ailanthus altissima tree of heaven Legal Status. 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. By 2008, the old tree was found to be dying and in danger of crashing into the building, which was about to undergo a major renovation. [23] The roots are poisonous to people. [7] Ailanthus is among the most pollution-tolerant of tree species, including sulfur dioxide, which it absorbs in its leaves. [7][23] In the east of its range it grows most extensively in disturbed areas of cities, where it was long ago present as a planted street tree. Its large, compound leaves are arranged alternately on the stem, and can be 30–60 cm long (occasionally up to 1 m long on vigorous young sprouts) and contain 11-33 leaflets, occasionally up to 41 leaflets. It is the only tree that grows out of cement. 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. Muell., orth. For more information on plant hardiness zones in Canada, visit Natural Resources Canada. [1] It is also unable to take dye. [1] The noxious odours have been associated with nausea and headaches, and with contact dermatitis reported in both humans and sheep, which developed weakness and paralysis. Trees of Canada →, Latin (scientific) name: Ailanthus altissima. [24], Several species of Lepidoptera utilise the leaves of ailanthus as food, including the Indian moon moth (Actias selene) and the common grass yellow (Eurema hecabe). [1] Ailanthus has become a part of western culture as well, with the tree serving as the central metaphor and subject matter of the best-selling American novel A Tree Grows in Brooklyn by Betty Smith. In China, the tree of heaven has a long and rich history. [23], 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 4.1 (approximately that of tomato juice). It can withstand cement dust and fumes from coal tar operations, as well as resist ozone exposure relatively well. 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. [44] It is a short lived tree in any location and rarely lives more than 50 years. On the west coast it is found from New Mexico west to California and north to Washington. Despite this, it was used extensively as a street tree during much of the 19th century. Tree of heaven is an opportunistic plant that thrives in full sun and disturbed areas. Native to China, non-native in U.S. glandulosa Desf.. A large, deciduous, often unisexual tree, frequently 50 to 70 ft, rarely loo ft high, with a trunk 2 to 3 ft in diameter, and a rounded head of branches. This fast growing tree can reach 80 feet in its relatively short life (50 years). Restrict human access? Ailanthus altissima. It has a smooth, grey bark with compound leaves which are alternate, odd-pinnate, with 11-25 lanceolate leaflets. All Images Enlarge Image. [7] In China it is often found in limestone-rich areas. [36] It sometimes enters undisturbed areas as well and competes with native plants. [6], A. altissima is a medium-sized tree that reaches heights between 17 and 27 metres (56 and 89 ft) with a diameter at breast height of about 1 m (40 inches). This derives from the literature of Zhuangzi, a Taoist philosopher, who referred to a tree that had developed from a sprout at the stump and was thus unsuitable for carpentry due to its irregular shape. For example, the city of Basel in Switzerland has an eradication program for the tree. [55] There are problems with using the wood as lumber, however. Ailanthus altissima, Ailanthus, Tree-of-heaven. Their styles are united and slender with star-shaped stigmas. [50] In its native range A. altissima is associated with at least 32 species of arthropods and 13 species of fungi. Click below on a thumbnail map or name for species profiles. The same study characterised the tree as using a "gap-obligate" strategy in order to reach the forest canopy, meaning it grows rapidly during a very short period rather than growing slowly over a long period. [7] On the other hand, a study in an old-growth hemlock-hardwood forest in New York found that Ailanthus was capable of competing successfully with native trees in canopy gaps where only 2 to 15% of full sun was available. Family Name: Simaroubaceae - Quassia Family. [56], Tree of heaven is a popular ornamental tree in China and valued for its tolerance of difficult growing conditions. The individual flowers are yellowish green to reddish in color, each with five petals and sepals. Common Name: Tree of Heaven: Scientific Name: Ailanthus altissima: Family: Simaroubaceae : Growth Form: Tree: Native Range: Central China: Invasive Range: The Tree of Heaven has invaded 42 of the 50 United States, including the majority of the East and West coasts. In the United Kingdom it is especially common in London squares, streets, and parks, though it is also frequently found in gardens of southern England and East Anglia. The twigs are stout, smooth to lightly pubescent, and reddish or chestnut in color. [68][69], Until March 26, 2008, a 60-foot (18 m)-tall member of the species was a prominent "centerpiece" of the sculpture garden at the Noguchi Museum in the Astoria section in the borough of Queens in New York City. However, enthusiasm soon waned after gardeners became familiar with its suckering habits and its foul smelling odor. Stems. [33] In South Africa it is listed as an invasive species which must be controlled, or removed and destroyed.[34]. He further writes (his emphasis): .mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}, For most landscaping conditions, it has no value as there are too many trees of superior quality; for impossible conditions this tree has a place; selection could be made for good habit, strong wood and better foliage which would make the tree more satisfactory; I once talked with an architect who tried to buy Ailanthus for use along polluted highways but could not find an adequate supply [...], In Europe, however, the tree is still used in the garden to some degree as its habit is generally not as invasive as it is in America. It can withstand very low phosphorus levels and high salinity levels. [23] It is frequently found in areas where few trees can survive. [26] Within China itself it has also been naturalized beyond its native range in areas such as Qinghai, Ningxia and Xinjiang. 30-50 cm long; petiolules ca. Each leaflet has one to three teeth on each side, close to the base. [4] Its suckering ability makes it possible for this tree to clone itself indefinitely. Studies found that Californian trees grew faster than their East Coast counterparts, and American trees in general grew faster than Chinese ones. While the species rarely lives more than 50 years, some specimens exceed 100 years of age. Interestingly, Tree-of-Heaven has another common name — Chinese sumac — which shows how similar these plants look, without closer inspection. Ailanthus, Chinese sumac, and stinking sumac. In North America, A. altissima is present from Massachusetts in the east, west to southern Ontario, southwest to Iowa, south to Texas, and east to the north of Florida. Native To: China ( Fryer 2010) Date of U.S. Introduction: It is also rare in Ireland. It is extremely fast-growing and it will grow almost anywhere. 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. [19] It has been introduced in many regions across the world. The tree grows rapidly and is capable of reaching heights of 15 m (50 feet) in 25 years. The name stems from the fact that A. altissima is one of the last trees to come out of dormancy, and as such its leaves coming out would indicate that winter was truly over. Scientific Name: Ailanthus altissima (Mill.) For many plants, the website displays maps showing physiographic provinces within the Carolinas and Georgia where the plant has been documented. It grows lushly...survives without sun, water, and seemingly earth. Scientific Name: Ailanthus altissima Common name: Tree of Heaven Page 1 of 2 QUESTION COMMENTS REFERENCE RANKING Social 1. For example, one study in Germany found the tree of heaven growing in 92% of densely populated areas of Berlin, 25% of its suburbs and only 3% of areas outside the city altogether. [15] The females can produce huge amounts of seeds, normally around 30,000 per kilogram (14,000/lb) of tree,[7] and fecundity can be estimated non-destructively through measurements of dbh.[14]. [7] In its native range it is found at high altitudes in Taiwan[22] as well as lower ones in mainland China. Ailanthus altissima Growing and Care Guide. [47] Another experiment showed a water extract of the chemical was either lethal or highly damaging to 11 North American hardwoods and 34 conifers, with the white ash (Fraxinus americana) being the only plant not adversely affected. Shade considerably hampers growth rates. J. Kelly. Ailanthus altissima /eɪˈlænθəs ælˈtɪsɪmə/,[3] commonly known as tree of heaven, ailanthus, varnish tree, or in Chinese as chouchun (Chinese: 臭椿; pinyin: chòuchūn; lit. : Certain sensitive individuals have found contact with plant parts to cause skin irritation and rashes. [7][9] The sepals are cup-shaped, lobed and united while the petals are valvate (i.e. No matter where its seed falls, it makes a tree which struggles to reach the sky. Scientific Name: Ailanthus altissima (Mill.) [8][16] The specific glandulosa, referring to the glands on the leaves, persisted until as late as 1957, but it was ultimately made invalid as a later homonym at the species level. A.K.A. [61] The plant may be mildly toxic. [5] It is considered a noxious weed and vigorous invasive species,[1] and one of the worst invasive plant species in Europe and North America.
