'''''Pyrus communis''''', known as the '''European pear''' or '''common pear''',<ref>{{cite web|url=http://apps.kew.org/trees/?page_id=123|title=Heritage Rare & Iconic Trees - Visit Kew Gardens|work=kew.org}}</ref> is a species of [[pear]] [[native plant|native]] to central and eastern Europe and southwest Asia.

Common European pear.
  
It is one of the most important fruits of temperate regions, being the species from which most [[orchard]] pear [[cultivar]]s grown in [[Europe]], [[North America]], and [[Australia]] have been developed. Two other species of pears, the Nashi pear (''[[Pyrus pyrifolia]]'') and the hybrid Chinese white or ya pear (''[[Pyrus × bretschneideri]]'', {{zh|c=白梨|p=báilí}}) are more widely grown in [[East Asia]].

==Origin==
 
The cultivated European pear (''P. communis'' subsp. ''communis'') is thought to be descended from two subspecies of wild pears, categorized as [[Pyrus pyraster|''P. communis'' subsp.'' pyraster'']] ([[syn.]] ''P. pyraster'') and ''P. communis'' subsp. ''caucasica'' (syn. ''P. caucasica''), which are [[interfertile]] with domesticated pears. Archeological evidence shows these pears "were collected from the wild long before their introduction into cultivation", according to Zohary and Hopf.<ref>{{cite book |first1=Daniel |last1=Zohary |first2= Maria |last2=Hopf |first3= Ehud |last3=Weiss|title=Domestication of Plants in the Old World: The Origin and Spread of Domesticated Plants in Southwest Asia, Europe, and the Mediterranean Basin |edition= Fourth |publisher=Oxford: University Press |year=2012 |page=176}}</ref> Although they point to finds of pears in sites in [[Neolithic]] and [[Bronze Age]] European sites, "reliable information on pear cultivation first appears in the works of the [[ancient Greece|Greek]] and the [[ancient Rome|Roman]] writers."<ref>{{cite book |first1=Daniel |last1=Zohary |first2= Maria |last2=Hopf |first3= Ehud |last3=Weiss|title=Domestication of Plants in the Old World: The Origin and Spread of Domesticated Plants in Southwest Asia, Europe, and the Mediterranean Basin |edition= Fourth |publisher=Oxford: University Press |year=2012 |page=177}}</ref> [[Theophrastus]], [[Cato the Elder]], and [[Pliny the Elder]] all present information about the cultivation and [[grafting]] of pears.
 
 
 
==Cultivation==
 
[[File:2015 Kwiatostan gruszy pospolitej.jpg|left|thumb|Pear tree in flower]]
 
European pear trees are not quite as hardy as [[apple]]s, but nearly so. However, they do require some winter chilling to produce fruit. A [[List of Lepidoptera that feed on pear trees|number]] of [[Lepidoptera]] [[caterpillars]] feed on pear tree leaves.
 
 
 
For best and most consistent quality, European pears are picked when the fruit matures, but before they are ripe. Fruit allowed to ripen on the tree often drops before it can be picked, and in any event will be hard to pick without bruising. Pears store (and ship) well in their mature but unripe state if kept cold, and can be ripened later, a process called [[bletting]]. Some varieties, such as [[D'Anjou|Beurre d'Anjou]], ripen only with exposure to cold.
 
 
 
Fermented pear juice is called [[perry]]. In Britain, the [[Perry (disambiguation)|place name "Perry"]] can indicate the historical presence of pear trees.
 
 
 
Relatively few cultivars of European or Asian pears are widely grown worldwide. Only about 20-25 European and 10-20 Asian cultivars represent virtually all the pears of commerce. Almost all European cultivars were chance seedlings or selections originating in western Europe, mostly France. The Asian cultivars all originated in Japan and China.  'Bartlett' (Williams) is the most common pear cultivar in the world, representing about 75% of US pear production.{{Citation needed|date=January 2010}}
