'''American Sweetgum''' (''Liquidambar styraciflua''), also known as '''Redgum''', is a [[deciduous]] [[tree]] in the genus [[sweetgum|''Liquidambar'']] native to warm temperate areas of eastern [[North America]].
==Description==
[[Image:Liquidambar-styraciflua-fruit.jpg|left|thumb|Immature "monkey ball" showing the paired capsule spikes]]
It is a medium-sized to large tree, growing to 20-35 m (exceptionally 41 m) tall, with a trunk up to 2 m diameter. The [[leaf|leaves]] are palmately lobed, 7-19 cm (rarely to 25 cm) long and broad and with a 6-10 cm petiole, looking somewhat similar to those of some [[maple]]s. They have five sharply-pointed lobes, but are easily distinguished from maples in being arranged alternately, not in opposite pairs. They are a rich dark green and glossy, and in most cases turn brilliant orange, red and purple colors in the [[autumn]]. A small percentage of trees are [[evergreen]] or semi-evergreen, with negligible fall color. The roots are fibrous; juices are balsamic.
The starry five-pointed leaves of the Liquidambar suggest the [[Sugar Maple]], and its fruit balls as they hang upon their long stems resemble those of the [[Buttonwood]]. The distinguishing mark of the tree, however, is the peculiar appearance of its small branches and twigs. The bark attaches itself to these in plates edgewise instead of laterally, and a piece of the leafless branch with the aid of a little imagination readily takes on a reptilian form; indeed, the tree is sometimes called '''Alligator-wood'''.<ref name=Keeler>{{cite book

The male and female [[inflorescences]] are on different branches of the same tree. The [[fruit]], popularly nick-named a "monkey ball", "bir ball, "gum ball" or "sticker ball", is a hard, dry, globose, compound fruit 2.5-4 cm in diameter and composed of numerous (20-50) [[capsule (fruit)|capsules]]. Each capsule has a pair of terminal spikes, and contains one to two small [[seed]]s.
The autumnal coloring is not simply a flame, it is a conflagration; in reds and yellows it equals the maples, and in addition it has the dark purples and smoky browns of the ash.<ref name=Keeler />
* Bark: Light brown tinged with red, deeply fissured, ridges scaly. Branchlets pithy, many-angled, winged, at first covered with rusty hairs, finally becoming red brown, gray or dark brown.
* Wood: Bright reddish brown, sapwood nearly white; heavy, straight, satiny, close-grained, not strong; will take a beautiful polish; warps badly in drying. Has been used with good results in the interior finish of sleeping-cars and fine houses. The wood is usually cut in veneers and backed up with some other variety which shrinks and warps less. Sp. gr., 0.5910; weight of cu. ft., 36.83 lbs.
* Winter buds: Yellow brown, one-fourth of an inch long, acute. The inner scales enlarge with the growing shoot, becoming half an inch long, green tipped with red.
* Leaves: Alternate, three to five inches long, three to seven inches broad, lobed, so as to make a star-shaped leaf of five to seven divisions, thse divisions acutely pointed, with glandular serrate teeth. The base is truncate or slightly heart-shaped. They come out of th ebud plicate, downy, pale green, when full grown are bright green, smooth, shining above, paler beneath. In autumn they vary in color from yellow through crimson to purple. They contain tannin and when bruised give a resinous fragrance. Petioles long, slender, terete. Stipules lanceolate, acute, caducous.
* Flowers: March to May, when leaves are half grown; monoecious, greenish. Staminate flowers in terminal racemes two to three inches long, covered with rusty hairs; the pistillate in a solitary head on a slender peduncle borne in the axil of an upper leaf. Staminate flowers destitute of calyx and corolla, but surrouned by hairy bracts. Stamens indefinite; filaments short; anthers introrse. Pistillate flowers with a two-celled, two-beaked ovary, the carpels produced into a long, recurved, persistent style. The ovaries all more or less cohere and harden in fruit. Ovules many but few mature.
* Fruit: Multicapsular spherical head, an inch to an inch and a half in diameter, hangs on the branches during the winter. The woody capsules mostly filled with abortive seeds resembling sawdust.<ref name=Keeler />
==Distribution==
Sweetgum is one of the most common southern [[hardwoods]]. It occurs in the [[United States]] from southern [[New York]] west to southern [[Missouri]] and east [[Texas]] and south to central [[Florida]], and in [[Mexico]] from southern [[Nuevo León]] south to [[Chiapas]], as well as in [[Guatemala]]. In the United States it occurs at low to moderate altitudes, while in Mexico and Guatemala it grows at high altitudes in mountains where the climate is more temperate.
==Cultivation==
As well as in its native area, it has been introduced to many parts of the world, including [[Argentina]], [[Australia]], [[Brazil]], [[Chile]], [[Europe]], [[Hawaii]], [[New Zealand]], [[South Africa]], [[Uruguay]] and [[Zimbabwe]]. In the [[United States]], it is especially popular in [[California]], where it has escaped from cultivation. In [[Florida]], it is sold at least as far south as [[Lake Worth, Florida|Lake Worth]]. In [[Canada]], it is commonly cultivated in cities of western [[British Columbia]] such as [[Victoria, British Columbia|Victoria]] and [[Vancouver]]. It also grows well at [[Toronto]] and [[Niagara Falls, Ontario|Niagara Falls]]. Farther east, it grows as a root-hardy [[shrub]] in [[Ottawa]] and [[Montreal]]. It grows best in moist, acidic [[loam]] or [[clay]] [[soil]], and tolerates poor drainage. Salt tolerance is moderate. [[Chlorosis]] can develop on alkaline soil, especially where organic matter is low.
===Selected cultivars===
* 'Burgundy' – dark red to purple fall colors may persist through winter.
* 'Clydesform' - sold as Emerald Sentinel®; columnar or narrowly pyramidal; slow growth to 9 meters; yellow-orange fall colors.
* 'Festival' – columnar; pale green summer leaves; bright fall hues of yellow, pink and red; less hardy than most.
* 'Goduzam' (Gold Dust) – variegated; pink to red-purple in fall.
* 'Grazam' – pyramidal, with glossy leaves. Orange, red and purple fall colors.
* 'Gumball' – dwarf shrubby cultivar seldom more than 2 meters tall. Purple-red fall color.
* 'Moraine' – upright, rounded form, fast growth, red fall color, hardy to −30 °C.
* 'Palo Alto' – various shades of red in fall; best in California.
* 'Parasol' – develops rounded crown; mature height 10 meters; deep red fall color.
* 'Rotundiloba' – sterile cultivar with rounded lobes on leaves.
* 'Slender Silhouette' - very narrow columnar form.
* 'Worplesdon' – cutleaf cultivar with orange, red and purple fall colors.
==Uses==
American Sweetgum is a popular [[ornamental tree]], grown for its intense fall colors, but it also has some drawbacks:
* The wood is brittle and the tree drops branches easily in storms.
* The spiked "gumballs" can be unpleasant to walk on, and their profusion can smother a lawn unless removed.
* Branches may have ridges or "wings" that cause more surface area, increasing weight of snow and ice accumlation on the tree.
[[Image:Liquidambar-styraciflua-ripen-fruit.jpg|thumb|Mature "monkey ball" of after seed dispersal]]
The [[wood]] is very compact and fine-grained, the [[heartwood]] being reddish, and, when cut into planks, marked transversely with blackish belts; it is used for [[veneer]] and [[pulpwood]], but is poor for [[timber]] or [[fuel]]. Being readily dyed black, it is sometimes used instead of ebony for picture frames, and other similar uses, but it is too liable to decay for outdoor work.
The gum resin, also known as '''liquid amber''' or '''copalm balsam''', yielded by this tree has no special medicinal virtues, being inferior in therapeutic properties to many others of its class. It is a kind of native [[balsam]], or resin, like [[turpentine]]. It may be clear, reddish or yellow, with a pleasant smell like [[ambergris]]. As it grows older, it hardens into a solid form, which historically was shipped to other countries in barrels. It was reputed an excellent balsam for mollifying and consolidating, and good against [[sciatica]], weakness of the nerves, etc. Mixed with [[tobacco]], the gum was once used for smoking at the court of the Mexican emperors. It was long used in [[France]] as a perfume for gloves and other such items. It is mainly produced in Mexico, little being obtained from trees growing in higher latitudes of North America, or in England.
An American Sweetgum will be featured as part of the Memorial Grove at the [[World Trade Center Memorial]], with installation set for fall 2008 and spring 2009 [http://www.renewnyc.com/displaynews.aspx?newsid=78d2035b-01cc-436e-b1cd-885cfb8e8989].
==History==
The earliest record of the tree appears to be in a Spanish work by F. Hernandez, published in 1651, in which he describes it as a large tree producing a fragrant gum resembling liquid amber, whence the name. In Ray's ''Historia Plantarum'' (1686) it is called ''Styrax liquida''. It was introduced into Europe in 1681 by John Banister, the missionary collector sent out by Bishop Compton, who planted it in the palace gardens at [[Fulham]].
The tree's immediate ancestor inhabited in tertiary times Alaska, Greenland and the mid-continental plateau of North America, a similar form is also found in the miocene in Europe.<ref name=Keeler />
