Although it is a genus name of the Caprifoliaceae (APG classification: Caprifoliaceae), in horticulture, the Japanese honeysuckle (Abelia grandiflora) is usually called Abelia. The Japanese honeysuckle (A. × grandiflora Rehd.) is a deciduous shrub distributed in central and southern China, with many flowers gathering at the ends of the branches and blooming, with the stamens protruding from the corolla. It is a horticultural hybrid made from A. chinensis R.Br. and A. uniflora R.Br., an evergreen shrub distributed in Fujian Province in southern China, and was created before 1880 and introduced to Japan around 1919 (Taisho 8). It is a semi-evergreen shrub of the Caprifoliaceae family that grows in clumps 1 to 2 meters tall. The leaves are opposite, ovate, 2.5 to 4 centimeters long, bluntly pointed at the tips, and have blunt sawtooth edges. The upper surface is glossy, the underside pale, and the midvein is hairy. It bears cone-shaped inflorescences at the ends of its twigs, with pale pink-white flowers that bloom continuously from July to November. The flowers are bell-shaped, about 2.5 cm long, and open into five lobes at the end, with 2 to 5 reddish-brown sepals. It has four stamens that are shorter than the corolla, and one pistil, but no fruit. The Japanese laurel grows well in sunny, moist, fertile soil in the Kanto region and south, but is not particularly picky about the soil. It is almost pest-free, grows quickly, tolerates pruning, is resistant to urban pollution, and has a long flowering season, so it is widely cultivated in parks and gardens. It is easy to propagate by cuttings, and can also be divided. [Yoshio Kobayashi December 14, 2021] kindsThere are about 20 species of Abelia distributed in East Asia and Mexico. In Japan, there are four species and their variants: Abelia japonica, Large Abelia japonica (Metsubaneutzi), Small Abelia japonica, and Taiwan Abelia japonica. Abelia japonica is a deciduous shrub that grows in the mountains of Honshu, Shikoku, and Kyushu south of the Kanto region, and blooms yellow-white flowers in May. Large Abelia japonica is very similar to Abelia japonica, but one of its five sepals is smaller, while Small Abelia japonica has two to three sepals.

スイカズラ科(APG分類:スイカズラ科)の1属名であるが、園芸上はハナゾノツクバネウツギ(ハナツクバネ)を通常アベリアとよんでいる。ハナゾノツクバネウツギA. × grandiflora Rehd.は、中国中南部に分布する落葉低木で花が枝先に多数集まって開き、雄しべが花冠より飛び出す。シナツクバネウツギA. chinensis R.Br.と、中国南部の福建省に分布する常緑低木のA. uniflora R.Br.とからできた園芸雑種で、1880年以前につくられ、日本には1919年(大正8)ごろに渡来。スイカズラ科の半常緑低木で高さ1~2メートルの株立ちになる。葉は対生し、卵形で長さ2.5~4センチメートル、先は鈍くとがり、縁に鈍い鋸歯(きょし)がある。表面は光沢があり、裏面は淡色で中脈には毛がある。小枝の先に円錐(えんすい)形の花序をつけ、7月から11月ごろまで淡桃白色の花が咲き続ける。花は釣鐘(つりがね)状で長さ約2.5センチメートル、先は5裂して開き、萼片(がくへん)は2~5枚あり紅褐色を帯びる。雄しべは4本で花冠より短く、雌しべは1本あるが果実はできない。 ハナツクバネは、関東地方以南の日当りのよい適湿の肥沃(ひよく)地でよく育つが、とくに土地は選ばない。病虫害はほとんどなく、成長が速く剪定(せんてい)に耐え、都市の公害にも強く、花期が長いので、公園や庭園に広く栽培されている。繁殖は挿木が容易で、株分けもできる。 [小林義雄 2021年12月14日] 種類アベリア(ツクバネウツギ)属は東アジアとメキシコに約20種が分布している。日本にはツクバネウツギ、オオツクバネウツギ(メツクバネウツギ)、コツクバネウツギ、タイワンツクバネウツギの4種とその変品種が分布。ツクバネウツギは関東地方以南の本州、四国、九州の山地に生える落葉低木で、5月に黄白色の花を開く。オオツクバネウツギはツクバネウツギとよく似ているが、5枚ある萼片のうち1枚が小さく、コツクバネウツギは萼片が2~3枚である。 [小林義雄 2021年12月14日] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
