''Lonicera sempervirens'' (also coral honeysuckle or trumpet honeysuckle) is a species of honeysuckle native to the eastern United States.〔USDA Plants Profile: (''Lonicera sempervirens'' )〕 It is grown as an plant for wildlife, as it is used by ruby-throated hummingbirds in their natural range.〔 It is also grown as an ornamental for its attractive flowers, especially as a native alternative to the invasive Japanese honeysuckle.〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=3414 )〕 Several cultivars have been selected for variation in flower color, including 'Magnifica' (flowers red outside, yellow inside), 'Sulphurea' (yellow flowers), and 'Superba' (bright scarlet flowers).〔Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan ISBN 0-333-47494-5.〕 The plant is evergreen in zone 8 and warmer and deciduous in colder climates. It is a twining vine growing to 20 ft or more through shrubs and young trees. The leaves are produced in opposite pairs, oval, up to 5 cm long and 4 cm broad; the leaves immediately below the flowers are perfoliate, joined at the base in a complete ring round the shoot. The flowers are produced in clusters of several groups of three together, tubular, 5 cm long, with five small lobes opening at the tip to expose the stamens and stigma; they are bright red to pinkish-red, and pollinated by ruby-throated hummingbirds and insects.〔Missouriplants: (''Lonicera sempervirens'' )〕〔Operation Rubythroat "Top Ten" Native Hummingbird Plants: (''Lonicera sempervirens'' )〕 ==Gallery== File:Ruby-throated Hummingbird (Archilochus colubris) RWD4.jpg|Ruby-throated hummingbird feeding File:Lonicera sempervirens.jpg|Flower buds File:Lonicera-sempervirens-foliage.jpg|Leaves and appearance after blooms detach File:Lonicera_sempervirens_close_up_bloom.JPG|Close-up of blooms 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「Lonicera sempervirens」の詳細全文を読む スポンサード リンク
