Betula pubescens (syn.
 "Betula alba"), commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree.
 It is closely related to, and often confused with, the silver birch ("B. pendula"), but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch ("B. nana").
Silver Birch House is the first play by the British-Turkish playwright Leyla Nazli.
 The play concerns the life of a peasant family in the Anatolian mountains during the 1960s and 1970s, a turbulent period in modern Turkish history.
 "Silver Birch House" was first staged in May 2007 at the Arcola Theatre in Dalston, London, as part of the Orient Express Season.
 It was directed by the Arcola's founder, Mehmet Ergen, and starred Peter Polycarpou in the role of the family patriarch Haydar.
 The play received largely positive reviews from London's theatre press.
Euceraphis betulae, the birch aphid or silver birch aphid, is a species of aphid in the order Hemiptera.

Birch sap or birch water is the sap directly tapped from birch trees, "Betula alba" (white birch), "Betula pendula" (silver birch), "Betula lenta", "Betula papyrifera", and "Betula fontinalis".
Betula pendula, commonly known as silver birch, warty birch or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe it is only found at higher altitudes.

 It has been introduced into North America, where it is known as the European white birch, and is considered invasive in some states in the United States and in parts of Canada.
 The tree can also be found in more temperate regions of Australia.
