''Amelanchier arborea'' (downy serviceberry〔 or common serviceberry), is native to eastern North America from the Gulf Coast north to Thunder Bay in Ontario and Lake St. John in Quebec, and west to Texas and Minnesota.〔 ''Amelanchier arborea'' is generally tall. Occasionally, it can grow up to tall and reach into the overstory. The trunk can be up to 15 cm diameter (rarely to diameter). The bark is smooth and gray.〔(【引用サイトリンク】url= http://www.missouriplants.com/Whitealt/Amelanchier_arborea_page.html )〕 The buds are slender with a pointed tip, and usually more than two scales visible. The leaves are ovate or elliptical, (rarely ) long and wide, with pointed tips and finely serrated margins. A characteristic useful for identification is that the young leaves emerge downy on the underside. The fall color is variable, from orange-yellow to pinkish or reddish.〔〔 It has perfect flowers that are diameter, with 5 petals, emerging during budbreak in early spring. The petals are white. Flowers are produced on pendulous racemes long with 4-10 flowers on each raceme. The flowers are pollinated by bees. The fruit is a reddish-purple pome, resembling a small apple in shape. They ripen in summer and are very popular with birds.〔〔〔Bioimages: (''Amelanchier arborea'' images )〕 It also commonly hybridizes with other species of ''Amelanchier'', the hybrid ''Amelanchier × grandiflora'' being one example,〔(【引用サイトリンク】Missouri Botanical Garden">url=http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=242791&isprofile=1& )〕 and identification can be very difficult as a result. ==Cultivation== This species tolerates varying light levels, but is at its best in full sun. It requires good drainage and air circulation and should be watered during drought. It is often confused with other species in the nursery trade. Propagation is by seed, divisions and grafting. The fruit is drier than some other serviceberries, and it is harvested locally for pies and jams; they were also used by Native Americans to make bread. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Amelanchier arborea」の詳細全文を読む スポンサード リンク
