''Radermachera sinica'', also called china doll, serpent tree or emerald tree, is an evergreen tree in the family Bignoniaceae, native to the subtropical mountain regions of southern China and Taiwan. It can reach heights of up to 30 m tall and a trunk diameter of 1 m. The leaves are bipinnate, 20 to 70 cm long and 15 to 25 cm broad, divided into numerous small glossy green leaflets 2 to 4 cm long. The flowers are white, trumpet-like, about 7 cm long, and resembling a large ''Bignonia'' flower in shape. Recent dwarf variations have been released, often referred to as the Asian Bell Tree. Foliage is highly attractive glossy, dark green & lacy. Consistently grows to maximum 3m and so makes a very popular indoor or patio plant, requiring a position with indirect sun light. Can be grown outdoors in tropical to subtropical regions. It should be planted in rich, well drained soil in full sun to part shade and protect from drying winds and frost. The specific name ''sinica'' means "from China". ==Cultivation== ''Radermachera sinica'' is often sold as a small houseplant, grown for its attractive glossy leaves; it does not normally flower indoors. It requires plenty of light and moisture in order to thrive. As with most houseplants, wilted leaves indicate either lack of water or overwatering. This plant can be grown outdoors in favourable climates like subtropical and Mediterranean climates. 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「Radermachera sinica」の詳細全文を読む スポンサード リンク
