'''''Quercus alba''''', the '''white oak''', is one of the preeminent [[hardwood]]s of eastern and central North America. It is a long-lived [[oak]], native to eastern and central [[North America]] and found from [[Minnesota]], [[Ontario]], [[Quebec]], and southern [[Maine]] south as far as northern [[Florida]] and eastern [[Texas]].<ref>{{BONAP|ref |genus=Quercus |species=alba}}</ref> Specimens have been documented to be over 450 years old.<ref>{{Cite web | url=http://www.ldeo.columbia.edu/~adk/oldlisteast/#spp |title = Eastern OLDLIST: A database of maximum tree ages for Eastern North America}}</ref>

Although called a white oak, it is very unusual to find an individual specimen with white bark; the usual colour is a light gray. The name comes from the colour of the finished wood. In the forest it can reach a magnificent height and in the open it develops into a massive broad-topped tree with large branches striking out at wide angles.<ref name=Keeler>{{cite book

== Description ==
''Quercus alba'' typically reaches heights of {{convert|80|to(-)|100|ft|order=flip|abbr=off}} at maturity, and its canopy can become quite massive as its lower branches are apt to extend far out laterally, parallel to the ground. Trees growing in a forest will become much taller than ones in an open area which develop to be short and massive. The [[Mingo Oak]] was the tallest known white oak at over two hundred feet with a trunk height of {{convert|145|ft|4=1|order=flip|abbr=on}} before it was felled in 1938.<ref>{{Cite web|last=Encyclopedia|first=West Virginia|title=September 23, 1938: Cutting of the Mingo Oak|url=https://www.wvpublic.org/post/september-23-1938-cutting-mingo-oak|access-date=2020-07-29|website=www.wvpublic.org|language=en|archive-date=2019-09-24|archive-url=https://web.archive.org/web/20190924030130/https://www.wvpublic.org/post/september-23-1938-cutting-mingo-oak|url-status=dead}}</ref> It is not unusual for the crown spread of a white oak tree to be as wide as it is tall, but specimens growing at high altitudes may only become small shrubs.    
The bark is a light ash-gray and peels somewhat from the top, bottom and/or sides.<ref name="FNA">{{eFloras|1|233501007|Quercus alba|family=Fagaceae|first=Kevin C.|last=Nixon}}</ref> According to Chris Bolgiano in ''The Appalachian Forest: A Search for Roots and Renewal'', the largest tree ever cut in [[West Virginia]] was a white oak that measured thirteen feet thick at its base.<ref>{{cite book |last1=Bolgiano |first1=Chris |title=The Appalachian Forest: a search for roots and renewal |date=1998 |publisher=Stackpole Books |location=Mechanicsburg, PA |isbn=0-8117-0126-3 |page=25}}</ref>
       
White oak may live 200 to 300 years, with some even older specimens known. The [[Wye Oak]] in [[Wye Mills, Maryland]] was estimated to be over 450 years old when it finally fell in a thunderstorm in 2002.<ref name=NAL>{{cite web |url=http://www.nal.usda.gov/speccoll/images1/wye.html |title=An American Champion: Maryland's Wye Oak |work=Special Collections |publisher=National Agricultural Library |date=June 12, 2002 |archive-url=https://web.archive.org/web/20020612131555/http://www.nal.usda.gov/speccoll/images1/wye.html |archive-date=June 12, 2002}}</ref>

Another noted white oak was the [[Basking Ridge White Oak Tree|Basking Ridge white oak]] in [[New Jersey]], estimated to have been over 600 years old when it died in 2016. The tree measured {{convert|25|ft|m|0|order=flip|abbr=on}} in circumference at the base and {{convert|16|ft|m|0|order=flip|abbr=on}} in circumference {{convert|4|ft|m|order=flip|abbr=on}} above the ground.

Sexual maturity begins at around 20 years, but the tree does not produce large crops of acorns until its 50th year and the amount varies from year to year. Acorns deteriorate quickly after ripening, the germination rate being only 10% for six-month-old seeds. As the [[acorn]]s are prime food for insects and other animals, all may be consumed in years of small crops, leaving none that would become new trees.<ref>{{FEIS |type=tree |last=Tirmenstein |first=D. A. |year=1991 |genus=Quercus |species=alba |access-date=2013-05-08}}</ref> The acorns are usually sessile, and grow to {{convert|1/2|to(-)|1|in|order=flip|abbr=on|round=5}} in length, falling in early October.

In spring, the young [[leaves]] are delicate, silvery pink, and covered with a soft blanket-like down. The petioles are short, and the clustered leaves close to the ends of the shoots are pale green and downy, resulting in the entire tree having a misty, frosty look. This condition continues for several days, passing through the opalescent changes of soft pink, silvery white, and finally, yellow green.<ref name=Keeler /><ref name=FNA />
The leaves grow to be {{convert|5|to(-)|8+1/2|in|cm|round=0.5|order=flip|abbr=off}} long and {{convert|2+3/4|to(-)|4+1/2|in|cm|round=0.5|order=flip}} wide and have a deep glossy green upper surface. They usually turn red or brown in autumn, but depending on climate, site, and individual tree genetics, some trees are nearly always red, or even purple in autumn. Some dead leaves may remain on the tree throughout winter until very early spring. The lobes can be shallow, extending less than halfway to the midrib, or deep and somewhat branching.

''Quercus alba'' is sometimes confused with the [[swamp white oak]], a closely related species, and the [[bur oak]]. The white oak hybridizes freely with the bur oak, the [[post oak]], and the [[chestnut oak]].<ref name=Keeler />

;Detailed description
* Bark: Light gray, varying to dark gray and to white; shallow, fissured and scaly. Branchlets start out as bright green, later turn reddish-green, and finally, light gray. A distinguishing feature of this tree is that a little over halfway up the trunk, the bark tends to form overlapping scales that are easily noticed and aid in identification.<ref name="FNA" />
* Wood: Light brown with paler sapwood; strong, tough, heavy, fine-grained and durable. Specific gravity, 0.7470; weight of one cubic foot, 46.35&nbsp;lbs; weight of one cubic meter 770&nbsp;kg.<ref name="FNA" /><ref>{{Cite web |url=https://nichetimbers.co.uk/stock/north-american/white-oak/ |title=White Oak • Niche Timbers |website=Niche Timbers}}</ref>
* Winter buds: Reddish brown, obtuse, {{convert|1/8|in|mm|0|order=flip|abbr=on}} long.<ref name="FNA" />
* Leaves: Alternate, {{convert|5-9|in|cm|order=flip|abbr=on|0}} long, {{convert|3-4|in|cm|round=0.5|abbr=on|order=flip}} wide. Obovate or oblong, seven to nine-lobed, usually seven-lobed with rounded lobes and rounded sinuses; lobes destitute of bristles; sinuses sometimes deep, sometimes shallow. On young trees the leaves are often repand. They come out of the bud conduplicate, are bright red above, pale below, and covered with white [[Trichome#Aerial surface hairs|tomentum]]. The reddish hue fades in a week or less, and they become silvery greenish, white, and shiny; when mature, they are thin, bright yellow-green, shiny or dull above, pale, glaucous or smooth below; the midrib is stout and yellow, primary veins are conspicuous.  In late autumn the leaves turn a deep red and drop, or on young trees, remain on the branches throughout winter. Petioles are short, stout, grooved, and flattened. Stipules are linear and caducous.<ref name=FNA />
* Flowers: Appear in May when leaves are one-third grown. Staminate flowers are borne in hairy aments {{convert|2+1/2 - 3|in|cm|round=0.5|order=flip|abbr=on}} long; the calyx is bright yellow, hairy, and six to eight-lobed with lobes shorter than the stamens; anthers are yellow.  Pistillate flowers are borne on short peduncles; involucral scales are hairy and reddish; calyx lobes are acute; stigmas are bright red.<ref name=FNA /> [[Extrafloral nectaries]] have been reported for this species.<ref>{{cite journal |date=2012-10-18 |first1=Marjorie G. |last1=Weber |first2=Kathleen H. |last2=Keeler |title=The phylogenetic distribution of extrafloral nectaries in plants |pages=1251–1261 |doi=10.1093/aob/mcs225 |journal=Annals of Botany |eissn=1095-8290 |volume=111 |issue=6|pmc=3662505 }}</ref>
* Acorns: Annual, sessile or stalked; nut ovoid or oblong, round at apex, light brown, shiny, {{convert|3/4 - 1|in|mm|round=5|order=flip|abbr=on}} long; cap is cup-shaped, encloses about one-fourth of the nut, tomentose on the outside, tuberculate at base, scales with short obtuse tips becoming smaller and thinner toward the rim.<ref name=Keeler /> White Oak acorns (referring to ''Q. alba'' and all its close relatives) have no epigeal dormancy and germination begins readily without any treatment. In most cases, the oak root sprouts in the fall, with the leaves and stem appearing the next spring. The acorns take only one growing season to develop unlike the red oak group, which require two years for maturation.<ref name=FNA />

== Distribution ==
[[File:White Oak in southwest Pennsylvania.jpg|thumb|White Oak in the Appalachian Foothills of SW Pennsylvania]]
''Quercus alba'' is fairly tolerant of a variety of habitats, and may be found on ridges, in valleys, and in between, in dry and moist habitats, and in moderately acid and alkaline soils. It is mainly a lowland tree, but reaches altitudes of 1,600&nbsp;m (5,249&nbsp;ft) in the [[Appalachian Mountains]]. It is often a component of the forest canopy in an [[oak-heath forest]].<ref>{{Cite web|url=http://www.dcr.virginia.gov/natural_heritage/ncTIIIe.shtml|archiveurl=https://web.archive.org/web/20110105224138/http://www.dcr.virginia.gov/natural_heritage/ncTIIIe.shtml|url-status=dead|title=''The Natural Communities of Virginia Classification of Ecological Community Groups'' (Version 2.3), Virginia Department of Conservation and Recreation, 2010|archivedate=January 5, 2011}}</ref><ref>Schafale, M.

Frequent fires in the Central Plains region of the United States prevented oak forests, including ''Q. alba'', from expanding into the Midwest. However, a decrease in the frequency of these natural fires after European settlement caused rapid expansion of oak forests into the Great Plains, negatively affecting the natural prairie vegetation.<ref>{{Cite journal|last=Abrams|first=Marc D.|date=May 1992|title=Fire and the Development of Oak Forests|journal=BioScience|language=en|volume=42|issue=5|pages=346–353|doi=10.2307/1311781|issn=0006-3568|jstor=1311781|s2cid=56082217}}</ref>

== Uses ==
=== Cultivation ===
''Quercus alba'' is cultivated as an [[ornamental tree]] somewhat infrequently due to its slow growth and ultimately huge size. It is not tolerant of urban pollution and road salt and due to its large taproot, is unsuited for a street tree or parking strips/islands.

=== Food ===
The acorns are much less bitter than the acorns of red oaks. They can be eaten by humans but, if bitter, may need to have the tannins leached.<ref>{{Cite book|last1=Elias|first1=Thomas S.|url=https://www.worldcat.org/oclc/244766414|title=Edible Wild Plants: A North American Field Guide to Over 200 Natural Foods|last2=Dykeman|first2=Peter A.|publisher=[[Sterling Publishing|Sterling]]|year=2009|isbn=978-1-4027-6715-9|location=New York|pages=228, 231|oclc=244766414|orig-year=1982}}</ref> They are also a valuable wildlife food, notably for turkeys, wood ducks, pheasants, grackles, jays, nuthatches, thrushes, woodpeckers, rabbits, squirrels, deer, and black bear.  The white oak is the only known food plant of the ''[[Bucculatrix luteella]]'' and ''Bucculatrix ochrisuffusa'' caterpillars.

The young shoots of many eastern oak species are readily eaten by deer.<ref name="Houston">Houston, David R. 1971. Noninfectious diseases of oaks.

=== Woodcraft ===
White oak has [[tylose]]s that give the wood a closed cellular structure, making it water- and rot-resistant. Because of this characteristic, white oak is used by [[cooper (profession)|coopers]] to make wine and whiskey barrels as the wood resists leaking. It has also been used in construction, shipbuilding, agricultural implements and in the interior finishing of houses.<ref name=Keeler /> White oak splints have been used historically by Native Americans for basketry.<ref>{{Cite journal |last=Banks |first=William |date=1953-03-01 |title=Ethnobotany of the Cherokee Indians |url=https://trace.tennessee.edu/utk_gradthes/1052 |journal=Masters Theses}}</ref>

=== Musical instruments ===
[[Deering Banjo Company]] have made several 5-string banjos using white oak - including members of the Vega series, the White Lotus, and the limited edition 40th anniversary model. White Oak has a mellower timbre than more traditionally used [[maple]], and yet still has enough power and projection to not require a metal tone ring.

The white oak from the movie ''[[The Shawshank Redemption]]'', known as the "[[Shawshank tree]]" and the "Tree of Hope", was estimated to be more than 200 years old when it fell. The tree is seen during the last ten minutes of the movie. As the movie gained fame, the tree became popular as well, and used to attract tens of thousands of movie fans and tourists every year. A portion of the tree came down on July 29, 2011, when the tree was split by lightning during a storm. The remaining half of the tree fell during heavy winds just short of five years later, on July 22, 2016.

The Bedford Oak is a 500-year-old white oak tree that sits in the town of [[Bedford (town), New York|Bedford]] in New York. It is the mascot of the town.
