They are named sweet azalea after their sweet-scented aroma. The flowers range in color from white to pink with red stamens. Their leaves can also become deep red to purple in the fall. This plant, indigenous to the United States, is generally found growing near moist areas or streams.〔(【引用サイトリンク】first=Susan )〕 The plant prefers growth in acidic soil with a pH of 6.8 or less. It grows best in sandy soils above 3000 feet. Their flowers are also known to contain poisonous substances and must not be consumed by wild animals or humans. The effects of consuming this plant include depression, vomiting, diarrhea, difficulty in breathing, and most dangerously coma. 〔(【引用サイトリンク】url=http://www.wildflower.org/plants/result.php?id_plant=RHAR3 )〕 ==History== The official credit for the discovery of ''R. arborescens'' goes to Frederick Traugott Pursh and John Bartram. They were first observed in John Bartram's garden in Philadelphia as well as Blue Mountain, Pennsylvania. 〔(【引用サイトリンク】first=Susan )〕 It has also been mentioned that the plant was initially noticed by François André Michaux in 1795 in the state of North Carolina. However, after further investigation, no more species were found in his conservatory. Therefore, the recognition for the discovery of the plant was given to Frederick Traugott Pursh and John Bartram. 〔(【引用サイトリンク】first=Susan )〕 ''Rhododendron arborescens'' were first named ''Azalea arborescens'' by Pursh in 1814. However, John Torrey renamed it ''Rhododendron arborescens'' in 1824 because he believed that they should not be taxonomically separated from the rhododendrons. 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「Rhododendron arborescens」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
