''Rhododendron schlippenbachii'', the royal azalea, is a species of ''Rhododendron'' native to the Korean Peninsula and adjacent regions of Manchuria (Liaoning, Nei Mongol), Japan, and the Russian Far East. It is the dominant understory shrub in many Korean hillside forests, growing at 400-1500 m altitude. It is a dense deciduous shrub growing to 4.5 m in height, but more commonly 1-2 m tall. The leaves are obovate, 4.5-7.5 cm long and 2.5-4.5 cm broad, with scattered glandular hairs. The flowers are white to pink, often with small red spots on the upper three petals; they are produced in late spring to early summer. The scientific name ''schlippenbachii'' is derived from Baron von Schlippenbach, a Russian officer who collected the species in 1854. ==Cultivation and symbolism== In Korea, it is called ''cheoljjuk'' (철쭉) and if the color of the petals is white, the flower is called ''huincheoljjuk'' (흰철쭉).〔http://www.seongju.go.kr/english/culture/plant3_24.jsp〕〔(【引用サイトリンク】script-title=ko:철쭉 )〕 The Royal Azalea is commonly chosen as a local symbol in South Korea, by cities and counties such as Gapyeong and Miryang. It is widely cultivated in other parts of the world; some cultivars bear white flowers. 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 schlippenbachii」の詳細全文を読む スポンサード リンク
