''Lonicera maackii'' (Overgrowing Choke-plant or Amur honeysuckle) is a species of honeysuckle in the family Caprifoliaceae, native to temperate Asia in northern and western China (south to Yunnan), Mongolia, Japan (central and northern Honshū, rare), Korea, and southeastern Russia (Primorsky Krai).〔Germplasm Resources Information Network: (''Lonicera maackii'' )〕 This overpopulated plant in North America is causing the destruction of many native species. It may be listed as an endangered species in Japan, but has been the bane of many botanists and biologists in North America due to its invasive nature.〔Ministry of the Environment (Japan): (Red List of Threatened Plants of Japan (excel spreadsheet) )〕〔Red Data Book (Japan): (''Lonicera maackii'' ) (in Japanese, with map; (google translation ))〕 It has escaped from cultivation and become naturalized in New Zealand and the eastern United States; in the forests of the latter, it has become an important invasive species.〔 It is a deciduous large shrub growing to 6 m tall with stems up to 10 centimeters diameter. The leaves are oppositely arranged, 5–9 cm long and 2–4 cm broad, with an entire margin, and with at least some rough hairs on them. The flowers are produced in pairs, commonly with several pairs grouped together in clusters; they are 2 cm long, two-lipped, white later turning yellow or light orange in color; flowering is from mid spring to early summer. The fruit is a bright red to black semi-translucent berry 2–6 mm diameter containing numerous small seeds; they ripen in autumn, and are eaten by birds, which disperse the seeds in their droppings. It is fast growing and favours shady habitats such as the forest understory, neglected urban areas, and fence rows. It can form extremely dense thickets.〔Huxley, A., ed. (1992).

Macmillan ISBN 0-333-47494-5.〕〔Missouriplants: (''Lonicera maackii'' )〕〔Invasive.org: (''Lonicera'' species (pdf file) )〕 == Cultivation and uses == It is grown as an ornamental plant for its attractive flowers, and also as a hedge. A number of cultivars have been selected for garden use, including 'Erubescens' with pink flowers, and 'Rem Red' with erect habit.〔 The flowers are sometimes used by children, who remove the blossom by hand, and pull off the bottom to suck out the sweet nectar in the center. The red berries are mildly poisonous to humans and should not be eaten. 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 maackii」の詳細全文を読む スポンサード リンク
